Castors are small wheels that are attached to furniture or equipment, providing mobility and ease of movement. There are different types of castors designed for specific purposes, such as office castors for use in an office setting, glides for easier movement across a floor, hard floor castors for use on hard floor surfaces, brake loaded castors with a brake mechanism that is activated when the furniture is loaded, brake unloaded castors with a brake mechanism that is activated when the furniture is not loaded, and replacement castors for replacing worn or broken castors. The choice of castor will depend on the specific needs and requirements of the application, and can provide a convenient and practical solution for making furniture or equipment mobile.

1. Office Castors: Designed for use in an office setting, these castors are typically made from a soft material to protect hard flooring.

2. Glides: These are non-rolling furniture accessories that are designed to allow furniture to be moved more easily across a floor.

3. Hard Floor Castors: These castors are designed for use on hard floor surfaces, such as hardwood or tile, and are typically made from a softer material than office castors.

4. Brake Loaded Castors: These castors have a brake mechanism that is activated when the furniture or equipment is loaded, providing stability and preventing movement.

5. Brake Unloaded Castors: These castors have a brake mechanism that is activated when the furniture or equipment is not loaded, allowing it to be easily moved.

6. Replacement Castors: These are replacement wheels for furniture or equipment that have worn out or broken castors.

Overall, castors are a convenient solution for making furniture or equipment mobile, and the type of castor selected will depend on the specific needs and requirements of the application.
