Frequently Asked Questions
What is the difference between the 80mm and 100mm options, and how do I choose?
The primary differences are wheel diameter, total fitted height, and load capacity. The 80mm castor has a total height of 106mm and supports up to 120kg per castor (360kg for a set of four), making it well suited to lighter trolleys, benches, and commercial furniture. The 100mm castor stands 127mm tall and carries up to 140kg per castor (420kg for a set of four), making it the better choice for heavier warehouse trolleys, industrial carts, and equipment platforms. If floor clearance or load capacity is a priority, choose the 100mm option. Both share identical top plate dimensions and hole centres, so they are interchangeable from a fitting perspective.
How does the directional brake work on these castors?
The directional brake is a foot-operated mechanism that, when engaged, locks the wheel to prevent it from rolling. This keeps the castor — and the equipment it is fitted to — stationary on the floor. Unlike a total-lock brake that also immobilises the swivel head, a directional brake allows the swivel to remain free while stopping forward and backward wheel movement. This is particularly useful on trolleys and carts where you want to hold a position without fully fixing the unit in place. To release, simply press or lift the brake lever with your foot.
Are these castors suitable for use on hard floors such as concrete, tiles, or resin?
Yes. Cast iron wheels with an 85 Shore A tread hardness are designed for use on hard, smooth, and semi-smooth floor surfaces including concrete, stone, ceramic tile, and sealed resin floors. They perform well in warehouses, workshops, factories, and commercial kitchens where firm flooring is standard. Cast iron wheels are not recommended for use on soft or delicate floor coverings such as carpet, vinyl, or polished hardwood, as the hard tread may cause surface marking or indentation under load.
What fixings do I need to fit these castors, and are they compatible with my existing equipment?
Both the 80mm and 100mm castors use a standardised 4-hole top plate measuring 100mm x 85mm, with hole centres of 80mm (long axis) and 60mm (short axis), and a hole diameter of 10mm. You will need four M10 bolts, washers, and nuts (not supplied) to secure each castor to your equipment. Before ordering, measure the existing hole pattern on your trolley, cart, or frame to confirm compatibility with these dimensions. The shared plate size across both variants means you can mix or upgrade between the 80mm and 100mm options without modifying your mounting surface.
