Description
50mm Pressed Steel Fixed Castor — Black Polypropylene Wheel, 4-Bolt Top Plate, 65 kg Load Capacity
A compact, robust fixed castor engineered for reliable straight-line mobility across furniture, display units, and light industrial equipment. Constructed with a pressed steel top plate and a durable polypropylene wheel, this castor delivers consistent, low-maintenance performance in commercial and domestic settings alike.
Product Overview
This 50 mm fixed castor is purpose-built for applications where controlled, directional movement is required. Unlike swivel castors, the fixed configuration keeps the wheel aligned in a single plane, making it the preferred choice for the rear positions of trolleys, carts, and furniture frames where straight tracking is essential.
The pressed steel top plate provides a rigid, secure mounting surface, while the 4-bolt hole pattern ensures a firm, vibration-resistant connection to the host structure. The black polypropylene wheel offers a practical balance of hardness and resilience, performing reliably on smooth concrete, tile, vinyl, and laminate flooring without marking or excessive noise. With a rated load capacity of 65 kg per castor and a combined capacity of 195 kg across a set of four, this unit is well suited to a broad range of light-to-medium duty tasks.
Commonly specified for office furniture, retail display stands, hospitality trolleys, workshop benches, and storage units, this fixed castor is a dependable, cost-effective mobility solution for everyday professional use.
