Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
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
Top Plate Swivel Castor
This 100mm swivel castor pairs a solid grey cast iron wheel with a zinc plated pressed steel swivel housing, giving a hard wearing, heat tolerant castor that carries up to 140kg per castor on trolleys, carts and workshop equipment.
The wheel runs on a ball journal bearing for an easy start and smooth turning, and the 100 x 85mm top plate with four bolt holes fixes flat under any frame or base. Cast iron will not flatten, split or melt, which makes it a dependable choice on rough concrete, around swarf and near hot work.
Why Choose This Castor
- ✓ Solid cast iron wheel that resists cuts, chips and flat spots
- ✓ 140kg load capacity per castor
- ✓ Ball journal bearing for smooth, low effort swivel and roll
- ✓ Zinc plated pressed steel housing for corrosion resistance
- ✓ Handles warm floors and hot work areas where plastic wheels fail
- ✓ Standard 100 x 85mm top plate for simple bolt on fitting
Load capacity is per castor. For a set of four, allow for uneven floors by planning on three castors carrying the load.
Where It Works Best
Fabrication and welding shops, foundries, machine shops, bakeries and ovens areas, engineering workshops and warehouses with rough concrete floors. Ideal for parts trolleys, welding carts, tool trolleys and equipment stands that need a hard wheel that shrugs off heat, oil and debris.
Frequently Asked Questions
How much weight can this castor carry?
Each castor is rated at 140kg. A set of four is best used for loads up to around 420kg, allowing for uneven floors.
Will a cast iron wheel mark or damage my floor?
Cast iron is a hard wheel, so it suits concrete and steel floors best. For tiled, vinyl or wooden floors a rubber or polyurethane wheel is the better choice.
Can it be used in hot areas?
Yes. The cast iron wheel copes with warm floors and hot work areas far better than plastic or rubber wheels.
What size bolts do I need?
The top plate has four 8mm holes on 60 / 80mm centres, so M8 bolts with nuts and washers are the right fit.
Is there a matching fixed castor?
Many customers pair two swivel castors with two fixed castors of the same wheel size and height for straight line tracking and easy steering.
How tall is the castor once fitted?
The overall height from floor to top plate is 127mm.
