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 and equipment that must move quietly and leave no marks on clean floors, this 100mm swivel castor is a dependable medium-duty choice. It has a blue non-marking elastic 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 160kg and stands 128mm tall. It suits hospital and laboratory trolleys, catering equipment, flight cases, retail and warehouse trolleys, and anywhere floors must be kept clean and unmarked.
Why it works
Blue non-marking elastic rubber tyre
The blue elastic rubber tyre is designed not to leave marks on floors, so it is widely used on hospital, laboratory, retail and food-area floors. The tread (hardness A64) absorbs bumps, grips well and runs quietly, and it copes with temperatures from -20°C to +80°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 80/77 x 60mm centres and suits M8 bolts.
- Blue non-marking elastic rubber tyre, quiet running
- Free-swivelling, no brake
- Roller bearing, 160kg per castor, 480kg for a set of four
- 105 x 85mm top plate, M8 fixings
- 128mm total height, 90mm swivel radius
Where it's used
Hospital, care home and laboratory trolleys, catering and food-preparation equipment, flight cases and staging, retail display and stock trolleys, clean-room carts and light warehouse trolleys. Suited to vinyl, tiles, sealed concrete, resin and other hard indoor floors where marking is not acceptable.
Choosing the right option
Choose blue non-marking rubber, as here, where floors must stay clean and quiet running matters; grey rubber is a lighter-duty alternative, and polyurethane suits heavier loads. 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. The matching 100mm blue non-marking castor with a total lock brake has the same 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 160kg, 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 rubber tyre away from oils and solvents, which can soften rubber.
Frequently asked questions
Will the blue wheel mark my floor?
No. The blue elastic rubber tyre is a non-marking compound, chosen for hospital, laboratory and retail floors where marks are not acceptable.
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 160kg. A set of four is rated to 480kg, because the load is calculated on three castors to allow for uneven floors.
Is there a braked version?
Yes. The same 100mm castor is available with a total lock brake that locks both the wheel and the swivel head, with the same plate and height.
