LINEAR BUSHINGS

Standard linear bushing / set

Bushing with steel cage. Suitable for high levels of pollution.

Compact linear bushing / set

Smaller bushing and radial clearance

Super linear bushing / set

Super A (self-alignment) , Super B (without self-alignment), Super H (capacity for heavy loads) and Super SH (highest load capacity)

Segmental linear bushing / set

Bushing with plastic cage. Very cost-effective. Anti-corrosive option.

Radial linear bushing / set

Highly precise bushing that supports heavy loads. Very smooth movement.

Anti-rotation linear set

We achieve an anti-rotation element by fixing one or several ball tracks in the gaps of the precision shaft.

Rotation + movement linear bushing

They are supplied with a deep-groove ball bearing or a needle bearing, to enable the bushing to rotate.

Precision shafts

Supplied machined according to the customer’s requirements. Made from chrome-plated anti-corrosive carbon steel.

Support blocks

We offer a wide variety of support blocks and solutions for mounting the shafts.
