75mm Twin Wheel Swivel Top Plate Castor – Grey Rubber, 60x60mm Plate, 90kg

For cabinets, trolleys and equipment with a flat base that need to roll quietly and treat the floor gently, this 75mm twin wheel top plate castor is a dependable choice. It has two grey rubber wheels on black centres, a zinc-plated pressed steel housing and a 60 x 60mm top plate that screws or bolts straight to the underside of your equipment. Each castor is rated to 90kg and stands 100mm tall. It suits mobile storage cabinets, stock and tool trolleys, shop display units, workbenches and office, school or healthcare furniture.

Why it works

Grey rubber tyres – quiet and floor-friendly

Each wheel has a grey rubber tyre on a rigid polypropylene centre. Rubber absorbs small bumps and grips the floor, so the castor runs more quietly and is kinder to vinyl, tiles, laminate and sealed wood than a hard plastic wheel. Grey rubber is less likely to leave dark scuff marks than black rubber.

Two wheels instead of one

The two 24mm-wide wheels turn independently as the castor swivels, so it changes direction easily with less scrubbing than a single wide wheel. The overall width across both wheels is 52mm and the swivel radius is 74mm.

Top plate fixing

The square 60 x 60mm plate has four slotted 6mm holes on 48mm and 37mm centres, so it lines up with more than one bolt pattern and suits M6 bolts, or screws into solid timber or board.

• Twin 75mm grey rubber wheels, quiet running
• 60 x 60mm top plate, M6 fixings
• 90kg per castor, 270kg for a set of four
• 100mm total height, 74mm swivel radius
• Zinc-plated pressed steel housing

Where it's used

Mobile storage cabinets and pedestals, stock and tool trolleys, workbenches, shop display units and fixtures, and office, school and healthcare furniture with a flat base. Best on smooth indoor floors such as vinyl, tiles, laminate, sealed wood and sealed concrete.

Choosing the right option

Check the fixing first: you need a flat area at least 60 x 60mm under each corner. If your equipment has tube legs with threaded inserts instead, the 75mm twin wheel bolt hole castor with the same wheels is easier to fit. Next, the wheel: grey rubber, as here, is the choice when quiet running and floor protection matter, while polypropylene wheels roll most easily on hard floors at a lower price. For the load, add up the weight of the item and everything in it and divide by three rather than four, because on an uneven floor one castor is often lifted; if the answer is over 90kg, choose a larger castor. This castor has no brake: the matching 75mm twin wheel top plate castor with grey rubber wheels and a total lock brake has the same plate and height, so two of each gives a level set that can be locked in place.

Installation, use and care

Hold the plate flat against the base and fix it through all four slotted holes with M6 bolts and nuts, or suitable screws into solid timber. Fixings are not included. Check they are tight after the first few weeks, keep the wheels clear of threads and debris, and wipe clean with a damp cloth. Keep rubber tyres away from oils and solvents, which can soften rubber.

Frequently asked questions

What size bolts or screws do I need?
The plate holes are 6mm, so use M6 bolts, or screws of a similar size into solid timber. Fixings are not supplied.

What is the load capacity?
Each castor is rated to 90kg. A set of four is rated to 270kg, because the load is calculated on three castors to allow for uneven floors.

Will the wheels mark my floor?
Grey rubber tyres are less likely to leave dark marks than black rubber and run quietly on hard floors. Keep them clean to avoid transferring grit.

Is there a braked version?
Yes. The matching 75mm twin wheel top plate castor with grey rubber wheels is also available with a total lock brake, with the same 60 x 60mm plate and 100mm height.
