General technical notes and information Linear Bushings and Shafts

Description

• Various versions:closed or open-type, standard or corrosion-resistant, with or without retaining rings, wiper seals and longitudinal seals, flanged or flangeless, Linear Sets
• Temperature stability up to 200 °C
• Long service life, high running speed and extra rigidity
• Outstanding running properties: low friction, quiet running
• Compensation for misalignment or shaft deflections

Main dimensions

DIN ISO 10285 Linear ball bearings – Metric series

This standard specifies the boundary dimensions, tolerances and terms for linear ball bearings. It divides Linear Bushings into size groups and tolerance grades.

DIN ISO 13012 Linear ball bearings – Accessories

This standard specifies the boundary dimensions and other useful dimensions of accessories for metric series linear ball bearings. Accessories include bearing housings, shafts, shaft support blocks and shaft support rails. It is used in conjunction with DIN ISO 10285.

Operating under difficult conditions

We recommend the following Linear Bushing models for applications with water-based coolants/lubricants:

• Standard Linear Bushings

For constantly humid or damp conditions (steam, condensation), we recommend the following corrosion-resistant Linear Bushing models with stainless steel parts in accordance with ISO683-17/EN 10088:

• Segmental Linear Bushing (corrosion-resistant version)

• eLINE Linear Bushing (corrosion-resistant version)

• Compact Linear Bushing (corrosion-resistant version)

• Standard Linear Bushing (corrosion-resistant version)
