80mm Braked Top Plate Castor – Blue Non-Marking Rubber, Total Lock, 150kg

For trolleys and equipment that must move quietly, leave no marks on clean floors and then stay firmly in place, this compact 80mm braked 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, a 105 x 85mm top plate and a foot-operated total lock brake that holds both the wheel and the swivel head. Each castor is rated to 150kg and stands just 108mm tall. It suits hospital and laboratory trolleys, catering equipment, 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.

Total lock brake – wheel and swivel held together

A standard wheel brake stops the wheel rolling but still lets the castor spin round. This castor's foot brake locks the wheel and the swivel head at the same time, so equipment stays exactly where you park it.

• Blue non-marking elastic rubber tyre, quiet running
• Total lock foot brake locks wheel and swivel together
• Roller bearing, 150kg per castor, 450kg for a set of four
• 105 x 85mm top plate, M8 fixings
• Compact 108mm total height, 118mm swivel radius

Where it's used

Hospital, care home and laboratory trolleys, catering and food-preparation equipment, retail display and stock trolleys, clean-room and pharmaceutical 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. For brakes, most equipment has total lock castors on two corners and plain swivel castors on the other two; the matching unbraked 80mm blue non-marking swivel castor 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 150kg, choose a larger wheel. Allow 118mm 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. Fit the castor so the brake pedal faces outwards where your foot can reach it. Check the fixings after the first few weeks, keep the wheel and brake clear of threads and debris, and wipe clean with a damp cloth. Keep the rubber tyre away from oils and solvents. Bring equipment to rest before applying the brake.

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 does "total lock" mean?
The foot brake locks both the wheel and the swivel head, so the castor can neither roll nor spin round.

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 150kg. A set of four is rated to 450kg, because the load is calculated on three castors to allow for uneven floors.
