Load check
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.

Details & FAQs
For trolleys, furniture and equipment that need to roll quietly and treat the floor gently, this 100mm swivel castor is a practical, economical everyday choice. It has a grey non-marking rubber tyre on a black polypropylene centre running on a roller bearing, a zinc-plated pressed steel housing and a 105 x 85mm top plate that bolts straight to the underside of your equipment. Each castor is rated to 80kg and stands 128mm tall. It suits office and school furniture, shop and stockroom trolleys, catering and cleaning trolleys, workbenches and light display units.
Why it works
Grey rubber tyre – quiet and floor-friendly
The grey rubber tyre is a non-marking compound, so it will not leave the dark scuffs that black rubber can, and it absorbs small bumps and runs quietly on hard floors. The tread (hardness A80) rolls easily under load. It copes with temperatures from -20°C to +80°C. Grey rubber is a lighter-duty wheel than the blue elastic rubber range, and is the economical choice where loads are moderate.
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.
Free swivel, top plate fixing
The swivel head turns a full 360 degrees so the castor follows the direction you push. The 105 x 85mm plate has four 8mm holes on 80 x 60mm centres and suits M8 bolts.

Where it's used
Office pedestals and storage units, school and library trolleys, shop display units and stockroom trolleys, catering and cleaning trolleys, workbenches and light equipment stands. Suited to vinyl, tiles, laminate, sealed wood, sealed concrete and other hard indoor floors.
Choosing the right option
Choose grey rubber, as here, for quiet running and floor protection at moderate loads; the blue elastic rubber range carries more weight at the same wheel size, and polyurethane suits heavier industrial use. Check you have a flat area at least 105 x 85mm under each corner for the plate. This castor has no brake: most equipment has braked castors on two corners and plain swivel castors like this one on the other two. If you add braked castors, choose ones with the same 128mm total height so the set sits level. 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 or the blue elastic rubber range. Allow 90mm 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. Check the fixings after the first few weeks, keep the wheel clear of threads and debris, and wipe clean with a damp cloth. Keep the rubber tyre away from oils and solvents, which can soften rubber.
Frequently asked questions
Will the grey wheel mark my floor?
Grey rubber is a non-marking compound, so it will not leave the dark scuffs black rubber can. Keep the tyre clean to avoid carrying grit.
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.
Can I mix this with braked castors?
Yes. Choose braked castors with the same 128mm total height and a matching plate so the equipment sits level.
