Zinc Plated Swivel Castors with Grey Thermoplastic Rubber Wheel
A free-rolling, top-plate swivel castor fitted with a grey thermoplastic rubber tread bonded to a polypropylene wheel centre, mounted on a zinc-plated pressed steel housing. Available in four wheel diameters — 60 mm, 80 mm, 100 mm, and 125 mm — with individual load ratings from 40 kg to 100 kg per castor. Engineered for retail trolleys, display units, warehouse carts, office furniture, and light-to-medium industrial equipment where smooth, quiet, floor-friendly movement is essential. The zinc-plated steel body resists everyday corrosion, while the 88 Shore A rubber tread delivers reliable grip and non-marking performance across vinyl, tile, laminate, polished concrete, and similar hard floor surfaces.

* Load ratings are per individual castor. Divide total equipment weight (including contents) by the number of castors fitted — typically four — to determine the required load rating per castor. Always apply an appropriate safety margin.
60 mm Wheel — 40 kg Load Capacity
The 60 mm swivel castor is the most compact option in this range, purpose-built for smaller retail trolleys, display stands, and lightweight mobile units where a low overall height and a tight turning circle are priorities. With a load rating of 40 kg per castor — 120 kg across a standard set of four — it provides dependable support for everyday retail and light commercial use. The 57 mm swivel radius enables responsive, nimble turns in confined aisles and display areas, while the 22 mm tread width keeps rolling resistance low on smooth hard floors. At just 87 mm total height, this is the ideal choice when ground clearance is limited or a low-profile castor is required.

80 mm Wheel — 50 kg Load Capacity
The 80 mm swivel castor steps up in both wheel diameter and load rating, carrying 50 kg per castor — 150 kg across a standard set of four. The larger wheel rolls more easily over minor floor imperfections, expansion joints, and surface transitions, making it a practical choice for retail trolleys, office furniture, and equipment that moves frequently across hard floor surfaces. A 70 mm swivel radius maintains good manoeuvrability while the 22 mm tread width keeps the rolling profile slim and efficient. At 107 mm total height, this castor suits mid-height frames and standard retail trolley bases.

100 mm Wheel — 80 kg Load Capacity
The 100 mm swivel castor is the mid-to-heavy option in this range, rated at 80 kg per castor — 240 kg across a standard set of four. The larger wheel diameter improves rollability over uneven surfaces, floor joints, and low thresholds, and noticeably reduces the push effort required to move loaded equipment. A 92 mm swivel radius suits larger trolleys and carts where a wider turning arc is acceptable. The upgraded 95 mm x 70 mm top plate with 8 mm fixing holes provides a more secure, stable mounting for heavier-duty frames and roll cages. The wider 30 mm tread distributes load more evenly and improves straight-line tracking under heavier weights.
Key Features

- Total Castor Height: 134 mm
- Load Capacity: 80 kg per castor (240 kg across a set of four)
- Swivel Radius: 92 mm
- Tread Width: 30 mm — wider contact for improved load distribution and stability
- Tread Hardness: 88 Shore A
- Wheel Material: Grey thermoplastic rubber on polypropylene centre
- Wheel Colour: Grey
- Bearing Type: Plain bearing
- Top Plate Dimensions: 95 mm (L) x 70 mm (W) — zinc-plated steel

125 mm Wheel — 100 kg Load Capacity
The 125 mm swivel castor is the largest and highest-rated option in this range, carrying 100 kg per castor — 300 kg across a standard set of four. The 125 mm wheel diameter rolls smoothly over floor joints, door thresholds, and minor surface irregularities, significantly reducing push effort on heavily loaded equipment. A 104 mm swivel radius suits large trolleys, roll cages, and industrial carts where a wider turning arc is expected. The 95 mm x 70 mm top plate with 8 mm fixing holes ensures a secure, stable mount on robust steel frames. The 30 mm tread width provides a broad contact patch that distributes heavy loads evenly and supports straight-line tracking under maximum load.

Frequently Asked Questions
Which size castor do I need for my trolley or equipment?
Select your size based on two factors: the load each castor must carry, and the floor clearance or overall height your equipment requires. For loads up to 40 kg per castor, the 60 mm wheel is the correct choice. For 41–50 kg, choose the 80 mm. For 51–80 kg, the 100 mm is appropriate. For loads up to 100 kg per castor — or where a taller overall height and greater rollability are needed — select the 125 mm. Always calculate the load per castor by dividing the total equipment weight, including contents, by the number of castors fitted. For a standard four-castor configuration, divide the total weight by four and apply a safety margin to account for uneven load distribution.
Will these castors mark or damage hard floors?
No. The grey thermoplastic rubber tread is a non-marking compound, making these castors suitable for use on vinyl, laminate, ceramic tile, polished concrete, and similar hard floor surfaces. The 88 Shore A hardness rating means the tread is firm enough to roll efficiently under load while remaining soft enough to avoid scuffing, scratching, or leaving residue on the floor surface. They are not recommended for use on soft flooring such as carpet, as the plain bearing and tread compound are optimised for hard, smooth surfaces.
How do I fit these castors to my equipment?
These castors are fitted via a 4-hole top plate using standard bolts or machine screws. The 60 mm and 80 mm variants use a 65 mm x 50 mm plate with 6 mm diameter fixing holes on 50 mm (length) x 36 mm (width) centres. The 100 mm and 125 mm variants use a larger 95 mm x 70 mm plate with 8 mm diameter fixing holes on 70 mm / 76 mm (length) x 50 mm / 44.4 mm (width) centres. Before ordering, measure your existing plate fixing pattern or frame mounting holes carefully and compare against the specifications above to confirm compatibility. Use appropriate bolts, washers, and locking nuts to ensure a secure, rattle-free installation.
Are these castors suitable for outdoor or damp environments?
These castors are designed primarily for indoor use on hard, dry floor surfaces. The zinc-plated steel body provides a degree of corrosion resistance suitable for typical indoor environments, including areas with occasional light moisture exposure such as loading bays, covered storage areas, or commercial kitchens. Prolonged or repeated exposure to standing water, rain, or highly humid conditions is not recommended, as this may affect the longevity of the plain bearing and the plate finish over time. For environments with regular moisture exposure, a stainless steel or nylon castor would be a more appropriate choice.
