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 must roll quietly and steer easily without marking the floor, this 100mm swivel castor is a hard-wearing, economical choice. It has a grey thermoplastic rubber (TPR) tyre bonded to a grey polypropylene centre, running on a roller bearing, with 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 100kg and stands 128mm tall. It suits shop and stockroom trolleys, catering and cleaning trolleys, office and school furniture, workbenches and mobile display units.
Why it works
Bonded TPR tyre – non-marking and hard-wearing
Thermoplastic rubber is a grey, non-marking tyre material, so it will not leave the dark scuffs that black rubber can. Because the tyre is bonded to the wheel centre rather than stretched on, it cannot shear off or creep round the hub under load, and it takes higher loads than a standard grey rubber tyre of the same size. The tread (hardness 88 Shore A) is firmer than soft rubber, so it rolls easily while still running quietly on hard floors. It copes with temperatures from -20°C to +60°C.
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.

- 105 x 85mm top plate, M8 fixings
- 128mm total height, 90mm swivel radius
Where it's used
Shop display units and stockroom trolleys, catering and cleaning trolleys, office pedestals and storage units, school and library trolleys, workbenches and light equipment stands. Suited to vinyl, tiles, laminate, sealed wood, sealed concrete and other hard indoor floors where marking is not acceptable.
Choosing the right option
Choose TPR, as here, for a non-marking wheel that is tougher and carries more than standard grey rubber; choose the blue elastic rubber range for the softest, quietest ride, and polyurethane for 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 total lock castors on two corners and plain swivel castors like this one on the other two; the 100mm TPR total lock castor has the same 128mm height and plate, so a mixed 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 100kg, choose a larger wheel. 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 tyre away from oils and solvents, and out of temperatures above 60°C.
Frequently asked questions
Will the grey wheel mark my floor?
No. Thermoplastic 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 is the difference between TPR and ordinary rubber?
The TPR tyre is bonded to the wheel centre, so it cannot shear off, and it is firmer and more hard-wearing than a standard grey rubber tyre while still running quietly.
Is there a braked version?
Yes. The same 100mm TPR castor is available with a total lock brake that locks both the wheel and the swivel head.
What size bolts do I need?
The plate holes are 8mm, so use M8 bolts and nuts. Fixings are not supplied.
