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.

Typical Applications
This swivel castor is well suited to a broad range of industrial and commercial settings. Common applications include warehouse trolleys and picking carts, manufacturing and assembly line equipment, workshop benches and tool cabinets, retail display units and stockroom shelving, logistics and distribution platforms, and hospitality service trolleys. The cast iron wheel construction makes it particularly effective on smooth concrete, resin, and hard floor surfaces where durability and load-bearing performance are priorities.
Frequently Asked Questions
What is the maximum load this castor can support?
Each castor is rated to a maximum load capacity of 140kg. When fitting a set of four castors, the combined maximum load is 420kg — though this assumes even load distribution across all four units. For applications with uneven weight distribution or dynamic loads, we recommend applying a safety margin and selecting a castor with a higher individual rating.
Is this castor suitable for use on concrete or hard floor surfaces?
Yes. The grey cast iron wheel is specifically suited to smooth, hard floor surfaces such as concrete, resin-coated floors, and compacted surfaces commonly found in warehouses, workshops, and manufacturing facilities. It is not recommended for use on soft, delicate, or polished flooring where surface protection is required.
How do I fit this castor to my equipment?
This castor uses a 4-hole top plate fixing method, making it straightforward to bolt directly onto the base of trolleys, benches, or equipment frames. The plate measures 100mm x 85mm with hole centres of 60mm and 80mm, and a hole diameter of 10mm. Standard M8 or M10 bolts are typically used. Always ensure the mounting surface is flat, structurally sound, and capable of supporting the intended load.
What is the overall height of the castor once fitted?
The total castor height from the base of the wheel to the top of the mounting plate is 127mm. This measurement is important when calculating the overall height of your equipment after fitting, particularly for trolleys or platforms with height restrictions or ergonomic requirements.
Sourced from trusted manufacturers and held in stock for prompt despatch, this pressed steel swivel castor is backed by the product knowledge and supply reliability that industrial and commercial buyers depend on.
