Fitting Types

Plate fitting is generally used for light duty, transport equipment and heavy duty castors. The castors are fitted to any equipment with a flat base by means of bolts and nuts.

The following specifications should be considered when selecting plate fitting:

Plate size, hole spacing, hole diameter

Stem Fitting:

Stem fitting is generally used for light duty and transport equipment castors. These castors are fitted by means of a plug-in.

The following specifications should be considered when selecting when selecting stem fitting:

Stem diameter, stem length

Bolt Hole Fitting:

Bolt hole fitting is generally used for light duty and transport equipment castors. Bolt hole fitting, a connection element is pushed through the bolt of the swivel head.

The following specifications should be considered when selecting when selecting stem fitting: hole diameter

Bolt fitting:

Bolt fitting is generally used for light duty castors. These castors are fitted to the transport unit by means of the threaded pin which is tightened to thread of cylindrical hole and a nut.

The following specifications should be considered when selecting when selecting stem fitting: screw diameter, screw length.

Expander Fitting:

Expander fitting is generally used for light duty castors. The castor is fitted by means of a synthetic square tube.

The following specifications should be considered when selecting when selecting stem fitting: tube shape (round or square), internal tube diameter.

Wheel bearing types

Ball bearing

The ball bearing is generally used for heavy duty castors and transport bearing equipment castors. It is resistant to shocks, easy and silent rolling. It has the smallest bearing play, lubricated with long-life grease and is maintenance-free under standard conditions. In addition to the standard type ball bearing is also available in stainless steel type.

Roller Bearing

The roller bearing is generally used for light duty castors and short distance transport equipment. It is resistant to shocks, strong, lubricated and long-life grease and is maintenance-free under standard conditions. In addition to the standard roller bearing is also available in stainless steel type.

Plain Bore Bearing

Th plain ball bearing is generally used for light duty castors, and short distance transport equipment. It is resistant to shocks and water. It is a simple, durable wheel, maintenance-free under standard conditions and cost-effective bearing.
