TX (LAGERBUS)

product

LAGERBUS TX is a steel bushing to improve mechanical resistance, with a porous sintered bronze layer for heat conductivity, dimensional stability and the adhesion of the POM sliding layer. The steel bushing is protected on the outside by a thin of copper, to prevent corrosion. Good automatic lubrication are recommended. (low wear and low friction)

APPLICATIONS

Hydraulics, Pneumatic and rotative movements

ASSEMBLY:

The LAGERBUS TX bushings are fitted in H7 housing. Once fitted, the bushing has H9 tolerance to allow to work with H7 shaft. This standard clearance must be adjusted depending on Pv and working temperature. The table presents the necessary clearance depending on the bushing diam and the Pv. The radial clearance increases by 0.01 mm for each temperature change of 20°C

 

MATERIAL STRUCTURE:

  • Steel  protected by a thin copper layer
  • A porous sintered bronze layer
  • A POM based sliding layer
  • Temperature limit -40°C+110°C
