This is all about how you want to fix your castor to your unit, and how much weight each castor is expected to carry.

Measure your top plate dimensions, in order to match any replacement castors. Alternatively measure your bolt dimesions or your threaded stem size. Also measure your fixing bolt size (D1) as we can supply fixing bolts and nuts. In order to measure thread size, simply measure the diameter of the thread, 8mm diameter equates to an M8 thread.

Top Plate Castors are fixed to your unit by 4 fixing bolts per castor, supplied sepeartely. Bolt Hole castors can attach either by using a threaded bolt or a tubular adaptor. Threaded Stem Castors are supplied with a stem that can screw into your equpment.
Top Tip! Attaching castors into round and square tube can be achieved by using bolt hole castors and castor tube adaptors.



We have a variety of sizes both in the round and square tubular expanding adaptor fittings and these can be found on our Accessories page. In order to choose the correct adaptor for your hollow tube, please follow the following steps

Swivel
Swivel with Brake
Top Tip! The following configurations are the most popular
Having an understanding of the weight you want the castors to support and move is a vital consideration! Use the following calculation
Max Load each castor needs to carry = (unit weight + max extra load) ÷3

Top tip! Dividing your total load by 3 allows for a margin of safety, and this will give you the maximum each castor can carry in a safe working environment, allowing for uneven floor surfaces.
Swivel Radius - The distance from the centre of the castor head fitting to the outside of the wheel. This measurement enables you to ensure you have enough clearance for the complete castor to rotate, without being fouled. It is important to take this into consideration when deciding where to attach the castor. Please note braked castors have slightly larger swivel radiuses, as a result of the foot brake mechanisms.
Floor Surfaces - All our stated load ratings for our castor ranges are based upon the assumption that the floor surface is reasonably level. Any obstructions, ridges, cracks or dirt will affect the load rating and efficiency of the castors. Careful consideration of Wheel Type in your castors is important and discussed in more detail below.
Health & Safety - All our castors are designed for low speed applications, and power towing castors are available upon special request. It is important to select the right castor for the job, to protect against manual handling injuries.
Bearings - Choosing castors and wheels with bearings, makes them easier to move, however in certain outdoor and offshore environments standard bearings may cease. Call us for information on stainless steel bearings.
Temperature - We offer a specialist range of Temperature Resistant castors that can withstand high temperatures in ovens, kilns and foundries. These castors can also withstand low temperatures such as in freezers and outdoor environments.
Choosing the right wheels applies to your castor selection and also if you just want to purchase any of our wheels. Choosing the right wheel for the job can make such a difference. To simplify your wheel selection we have highlighted a number of factors for you to consider
1. Wheel Diameter – the larger the wheel the easier it is to move and the more weight it can carry. Measure the diameter of the wheel from outside edge to outside edge.

2. Hub Bore – is the diameter of the hole at the centre of the wheel is an important measurement. To double check you can measure the diameter of your axle and the measurements should be the same. This does vary in different wheels and the hub bore can be reduced to suit your application with the addition of bearings, or collars and tubes. Please have a look at our accessories page for more information on reducing the hub bore diameter.
3. Wheel Load Capacity – all of our wheels have been tested and are able to carry the specified load capacities. Look for the symbol. Weight bearing abilities can be affected by floor surfaces and amount of use overtime. Overloading wheels will cause them to fail!
4. Tread Width – is the width of the wheel that touches the floor surface. Different types of wheel have differing tread widths. Wide tread wheels are ideal for outdoor environments.
5. Hub Length – this is the width of the hub bore , and can be measured as the width of the centre of the wheel. Getting the right hub length is important, because if you purchase a wheel with the hub bore being too small the wheel will wobble on the axle. If the hub length is too big it won’t fit onto your axle. All our wheels that fit our castors are designed to suit and delivered ready assembled to you, so you don’t have to worry!

6. Wheel Type – Wheels can be simply categorised into 2 types, soft tread wheels and hard tread wheels. The general principle is hard tread wheels on softer floor surfaces, and soft tread wheels on harder floor surfaces. This principle reduces the rolling tractive resistance and makes the wheels easier to move.
7. Hard Tread Wheels – such as Nylon Wheels, Polypropylene Wheels, Phenolic High Temperature Wheels and Cast Iron Wheels are easiest to manoeuvre, as they have a lower rolling resistance against the floor surface. They are durable, strong and long lasting, depending upon their application. They can at times be considered to be noisy and can damage some floor surfaces. But these hard tread wheels remain our best sellers for every day applications.
8. Soft Tread Wheels – such as Solid Rubber Wheels, Pneumatic Rubber Wheels, High Temperature Rubber Wheels and Polyurethane Wheels. Soft Tread Wheels are generally kinder to the floor surfaces, make less noise and some are even non marking rubber wheels. Polyurethane wheels tend to sit in-between the two types of wheels, as they have a hard nylon, cast iron or aluminium centre with a softer polyurethane tyre bonded on. This makes the polyurethane wheels some of the most versatile wheels in the range.
9. High Temperature Wheels – we offer a range of hard tread phenolic resin temperature resistant wheels along with a soft tread high temperature rubber wheels.
10. Bearings – there are a number of bearings to choose from depending upon your wheel type, load ratings and application.
Plain Bearings – Wheels with no bearings
Roller Bearings – A bearing collar containing needle roller bearings, often the most common and well used bearings. Most suitable for medium duty applications, making the wheel easier to move.
Ball Journal Bearings & Tapered Roller Bearings – precision bearings, for heavier load applications
Stainless Steel Bearings – are also available for outdoor environments and food manufacturing plants.

There are 2 key measurements you need to check?
Handwheels, Thumb Screws, T Grips and clamping handles are chosen by weather they have a male or female thread.

Male Thread

Female Thread
Our Handwheels, Thumb Screws, T Grips and clamping handles come with a range of thread diameters from M5 up to M16.
In order to choose the correct handgrip, it is important to measure the external diameter of the tube or handlebar the grip is going onto. We offer handgrips from 12.5mm ( ½”) up to 32mm (1.1/4”). As a check you could measure the internal diameter of the handgrip and the two measurements should be the same. We offer economy up to heavy duty handgrips, and one of the most popular styles in the natural rubber handgrip version.

Handle Grip
What weight do you need your Kenda tyres to carry, and at what top speed?
The Kenda range uses a code system to help you to identify which tyres are right for your needs. Each tyre has a number that tells you what weight it can support, and a letter that tells you the maximum speed that the tyre can move at when carrying that weight.
Below are two tables that show the maximum loads and maximum speeds of the Kenda tyre range. You will find these codes in the product descriptions. Use the below tables to determine the load/speed rating of that particular tyre.
For example, 30C would be a tyre that can carry 106kg at a maximum speed of 60kmph/37mph.

Commercial Spring loaded Steps provide a safe and efficient solution for accessing elevated areas in industrial settings.
Commercial Spring loaded Steps are mobile steps equipped with a spring mechanism that automatically retracts the steps when not in use, ensuring they remain stationary during use. This design enhances safety by preventing unwanted movement and allows for easy relocation when the steps are needed elsewhere. Typically constructed from robust materials such as steel, these steps are designed to withstand frequent use in demanding environments.
These steps are commonly used in warehouses, factories, and other industrial environments where workers need to access high shelves or machinery. Their mobility makes them ideal for dynamic workspaces where fixed steps may not be practical.
When selecting Commercial Spring loaded Steps, consider the height and number of steps required for your specific application, as well as the weight capacity needed to safely support users and any equipment they might carry.
When selecting the height of Commercial Spring loaded Steps, consider the maximum elevation you need to reach and ensure the steps provide comfortable access to that height. It's important to measure the distance between the floor and the desired working height to choose steps that allow users to work safely without overreaching. Additionally, check that the steps comply with any relevant safety regulations for your industry.
While primarily designed for indoor use, some Commercial Spring loaded Steps may be suitable for outdoor environments, provided they are made from weather-resistant materials. It's essential to verify the manufacturer's specifications regarding outdoor use and ensure that the steps are used on stable, level surfaces to maintain safety.
Regular maintenance of Commercial Spring loaded Steps involves inspecting the spring mechanism for any signs of wear or damage, ensuring that all components are securely fastened, and checking the non-slip treads for wear. Cleaning the steps to remove dirt and debris will help maintain their functionality and safety. If any parts appear damaged or worn, they should be repaired or replaced promptly to prevent accidents.
