Braked Castors
Braked castors, also known as lockable castors, are designed to provide controlled movement and secure positioning for industrial, commercial and material handling equipment.Most braked castors are swivel castors fitted with wheel brakes, directional locks or total stop braking systems for improved safety and st...ability. Braked castors can include different locking mechanisms depending on the application requirements:
- Wheel Brake – Locks the wheel to prevent rolling
- Directional Lock – Locks the swivel movement for straight-line travel
- Total Stop Brake – Locks both wheel rotation and swivel movement simultaneously
Most brake systems are fitted to swivel castors. Fixed castors with brakes are less common, although some specialist heavy-duty and shock-absorbing castors include braking systems.
Braked Castor Construction
Swivel braked castors rotate 360 degrees around a vertical swivel axis and consist of a castor wheel mounted within a swivel housing or bracket. The main components typically include:
- Top plate or bolt hole fitting
- Swivel head and ball race
- Castor bracket or yoke
- Wheel and axle assembly
- Brake mechanism
The top plate or fixing determines how the castor attaches to equipment. Common fixing methods include top plate fixings and single bolt hole fittings. Correct bolt hole centres are important when replacing existing castors.
Single & Double Ball Race Bearings
The swivel head contains ball bearings which allow the castor to rotate smoothly under load. Braked swivel castors are commonly available with:
- Single ball race bearings
- Double ball race bearings
Double ball race designs are widely used for medium-duty and heavy-duty applications because they provide improved load distribution, smoother steering and greater durability under static and dynamic loads.
What is Castor Offset?
Castor offset is the distance between the swivel axis and the centre of the wheel axle. This offset allows swivel castors to self-align and travel in the direction of movement, improving manoeuvrability and steering performance during operation. Read More

The castor is fully compressed at 120kg. The shock absorbing movement also means that the castors off set can range from 36mm to 50mm.
