Other properties
Version Standard
Format of linear bushings – Closed
Series Compact
Seal 1 integrated wiper seal
Lubrication Not lubricated
Maximum dynamic load capacity Cmax 900 N
Maximum acceleration rate amax 150 m/s²
Maximum permissible linear speed vmax 5 m/s
Permissible ambient temperature (min. ... max.) -10 °C ... +80 °C

Note: friction coefficient μ Friction coefficients of unsealed linear bushings when lubricated with oil. The friction coefficient is lowest under heavy load, but can still be above the specified value even under a low load.
Footnote breakaway force One wiper seal: Multiply value with factor 0.5
Footnote maximum dynamic load capacity Cmax The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.
Footnote minimum dynamic load capacity Cmin The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.
Footnote friction force FR One wiper seal: Multiply value with factor 0.5
Breakaway force 1.8 N

Description

Compact linear bushing Shaft diameter d = 14 With one seal Radial clearance: Standard Version: Standard Not greased

Features
  • Low-cost linear bushing for general requirements
  • Small outer dimensions and highly compact construction
  • High dynamic load rating and long service life due to hardened segmental load-bearing plates with ball conformity in the running track
  • High travel speed (5 m/s)
  • Integrated wiper seals, external seals or no wiper seals
  • Normal radial clearance
  • Not greased
  • Simple mounting: Just press on – no additional retention needed
  • Many pockets acting as lubricant reservoirs for extended lubrication intervals or lubrication for life
  • Pockets collect any dirt that may have worked its way in to prevent the linear bushing from jamming.
  • Integrated metal retainer about 0.1 mm larger than outer diameter (shaft diameters 12 to 50) for secure fit in housing bore
