100mm Pressed Steel Swivel Castor with Directional Brake
What This Product Is
This 100mm pressed steel swivel castor combines precision engineering with practical functionality, featuring a directional brake mechanism and a black rubber on polypropylene wheel. Designed with a ball journal bearing system, it delivers smooth 360-degree rotation while maintaining the ability to lock into straight-line travel when needed.
Built for light to medium-duty applications, this castor supports up to 75kg per unit and is ideal for trolleys, mobile workstations, handling equipment, and industrial carts where controlled manoeuvrability and directional stability are essential.
Key Performance Features
Directional Brake Control: The swivel head locks to enable straight-line movement, preventing unwanted rotation during transport or positioning tasks.
Ball Journal Bearing: Ensures smooth, low-friction rotation under load, reducing effort during manoeuvring and extending operational lifespan.
Floor-Friendly Wheel: The black rubber tread on polypropylene core provides excellent shock absorption, vibration dampening, and protects floor surfaces from marking or damage.
Robust Construction: Pressed steel housing with zinc plating offers durability and corrosion resistance for demanding indoor environments.
Secure Top Plate Mounting: Four-bolt-hole top plate design ensures reliable, stable attachment to equipment bases.

Frequently Asked Questions
What is a directional brake and how does it work?
A directional brake locks the swivel mechanism of the castor, restricting movement to a straight line only. When engaged, the castor can roll forwards and backwards but cannot rotate, making it ideal for guiding equipment along specific paths or preventing unwanted turning during transport.
Is this castor suitable for outdoor use?
This castor is designed primarily for indoor applications. While the zinc-plated pressed steel housing offers some corrosion resistance, prolonged exposure to moisture, UV light, and extreme temperatures may reduce performance and lifespan. For outdoor environments, consider castors specifically rated for exterior use.
What type of flooring is this castor compatible with?
The black rubber on polypropylene wheel is floor-friendly and suitable for most hard indoor surfaces including concrete, tile, vinyl, laminate, and sealed wood. The 85 Shore A tread hardness provides good shock absorption while minimising floor marking and noise. Avoid use on soft or uneven surfaces where the wheel may sink or struggle to roll smoothly.
How do I install this top plate castor?
Installation requires four bolts (not included) that fit through the 10mm diameter holes in the top plate. Ensure the mounting surface is flat, clean, and structurally sound. Position the castor with the plate hole centres aligned at 60mm × 80mm spacing, then secure with appropriate fasteners. Tighten bolts evenly to prevent plate warping and ensure stable load distribution.
