Track Rollers in X-life Quality

Track rollers are self-retaining, single or double row units with particularly thick-walled outer rings. These bearings can support axial forces in both directions as well as high radial forces. The bearing outer rings have a crowned or cylindrical outside surface. Designs with a crowned outside surface are used where there is misalignment in relation to the raceway and edge stresses must be avoided. The track rollers are available with an inner ring, with a stud and with a plastic tyre on the outer ring.

 

INA track rollers LR52 and LR53 – now available in X-life quality

INA track rollers series LR52 and LR53 are now available in X-life quality. They can now transmit higher radial loads and have a longer rating life thanks to the optimized internal design.
The external dimensions of the new bearings have not changed, which means they can replace earlier bearings without difficulty.

 
INA track rollers LR52 and LR53

The advantages at a glance

  • Higher load carrying capacity
  • Improved protection against contamination
  • Large grease reservoir
  • Low bearing temperatures
  • Less strain is placed on the lubricant
  • Downsizing possible
  • Identical external dimensions
 
 
 

New seals for more efficiency

The seal concept was also revised at the same time as the optimized internal design. INA track rollers LR52 and LR53 are supplied with HRS seals as standard or with the new Z seal as an option. Both seals offer significantly higher sealing action compared with the previous version.

 
HRS seal

HRS seal

  • Innovative lip contact design
  • Axial contact between the inner ring and the seal lip
  • Keeps grease in the bearing and contamination out
  • DEHP free
 
Z seal

Z seal

  • Optimized Z sealing shield with labyrinth sealing function
  • Function of inner and outer ring adapted for Z shield
  • Wider operating temperature range is possible if a combination of a steel cage and adapted greasing is used
 
 

X-life – premium quality for rolling bearings

The improved INA X-life LR52 and LR53 track rollers feature numerous design details that result in up to 10 % higher dynamic load ratings and up to 15 % higher static load ratings.

 
Comparison of the dynamic load rating with that of the next best competitor
  • Unchanged outside diameter
  • Heavy-section outer ring
  • Optimized internal construction
  • Contact angle optimized for higher load carrying capacity
  • Innovative seal design Also available with an improved steel sealing shield
  • Optimized polyamide cage Robust and rigid steel cage available as an option
  • Increased speed limits
