160mm Swivel Top Plate Castor – Blue Non-Marking Rubber, Roller Bearing, 300kg

For trolleys and equipment that must move quietly and leave no marks on clean floors, this 160mm 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 140 x 110mm top plate that bolts straight to the underside of your equipment. Each castor is rated to 300kg and stands 200mm 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 A70) 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 140 x 110mm plate has four 10mm holes on 105 x 75/80mm centres and suits M10 bolts.

• Blue non-marking elastic rubber tyre, quiet running
• Free-swivelling, no brake
• Roller bearing, 300kg per castor, 900kg for a set of four
• 140 x 110mm top plate, M10 fixings
• 200mm total height, 136mm 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 warehouse and distribution 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 140 x 110mm 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 160mm 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 300kg, choose a larger wheel or a heavy-duty castor. Allow 136mm 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 M10 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 10mm, so use M10 bolts and nuts. Fixings are not supplied.

What is the load capacity?
Each castor is rated to 300kg. A set of four is rated to 900kg, because the load is calculated on three castors to allow for uneven floors.

Is there a braked version?
Yes. The same 160mm castor is available with a total lock brake that locks both the wheel and the swivel head, with the same plate and height.
