100mm Braked Top Plate Castor – Black Rubber Wheel, Total Lock, 80kg

For workshop trolleys, machinery stands and equipment that need a tough, quiet-running wheel and a brake that holds them firmly in place, this 100mm braked castor is a practical, economical choice. It has a black rubber tyre on a black polypropylene centre running on a roller bearing, a zinc-plated pressed steel housing, a 105 x 85mm top plate and a foot-operated total lock brake that holds both the wheel and the swivel head. Each castor is rated to 80kg and stands 128mm tall. It suits workshop and tool trolleys, machine and equipment stands, warehouse and stockroom trolleys, and workbenches.

Why it works

Black rubber tyre – quiet, grippy and hard-wearing

The black rubber tyre absorbs small bumps, grips well and runs far more quietly than a hard nylon or steel wheel. It copes with temperatures from -20°C to +80°C. Black rubber can leave dark marks on pale or polished floors, so for hospitals, shops and clean areas choose the grey or blue non-marking versions instead.

Roller bearing for easier rolling

The wheel runs on a roller bearing rather than a plain bore, so it takes less effort to start and keep moving under load, and it wears more evenly over time.

Total lock brake – wheel and swivel held together

A standard wheel brake stops the wheel rolling but still lets the castor spin round. This castor's foot brake locks the wheel and the swivel head at the same time, so equipment stays exactly where you park it.

• Black rubber tyre, quiet and hard-wearing
• Total lock foot brake locks wheel and swivel together
• Roller bearing, 80kg per castor, 240kg for a set of four
• 105 x 85mm top plate, M8 fixings
• 128mm total height, 118mm swivel radius

Where it's used

Workshop and tool trolleys, machine and equipment stands, warehouse, stockroom and garage trolleys, and workbenches. Best on concrete, sealed concrete, resin and other hard floors where occasional tyre marks are not a concern.

Choosing the right option

Choose black rubber, as here, for quiet, grippy running on workshop and warehouse floors; choose grey or blue non-marking rubber where floor appearance matters, and polyurethane for heavier industrial loads. Check you have a flat area at least 105 x 85mm under each corner for the plate. For brakes, most equipment has total lock castors on two corners and plain swivel castors on the other two. For the load, add up the weight of the item and everything on it and divide by three rather than four, because on an uneven floor one castor is often lifted; if the answer is over 80kg, choose a larger wheel. Allow 118mm of swivel clearance around each castor.

Installation, use and care

Hold the plate flat against the base and fix it through all four holes with M8 bolts and nuts. Fixings are not included. Fit the castor so the brake pedal faces outwards where your foot can reach it. Check the fixings after the first few weeks, keep the wheel and brake clear of threads and debris, and wipe clean with a damp cloth. Keep the rubber tyre away from oils and solvents. Bring equipment to rest before applying the brake.

Frequently asked questions

Will the black wheel mark my floor?
Black rubber can leave dark marks on pale or polished floors, especially when turning under load. For those floors, choose the grey or blue non-marking versions.

What does "total lock" mean?
The foot brake locks both the wheel and the swivel head, so the castor can neither roll nor spin round.

What size bolts do I need?
The plate holes are 8mm, so use M8 bolts and nuts. Fixings are not supplied.

What is the load capacity?
Each castor is rated to 80kg. A set of four is rated to 240kg, because the load is calculated on three castors to allow for uneven floors.
