Hybrid roller bearing WJRM-BB-31  

Lubrication-free smooth operation: WJRM-BB-31 & 41

New drylin® W hybrid roller bearing with ball bearings

The drylin® W hybrid roller guide WSR combines function and design. In lateral installation position, doors, boards, shelves or monitors can be moved. And it is now even easier and with less effort. Because the matching drylin® W hybrid roller bearings are now also available with smooth-running ball bearings. The combination of the optimised roller alignment of single/double rollers and integrated ball bearings (BB) reduces the coefficient of friction by half and is therefore ideal for all manual adjustments. The two roller bearing versions WJRM-31-10-BB and WJRM-41-10-BB supplement the modular system of the drylin® W hybrid roller guide.
 

  • Rollers and sliders made of wear-resistant, lubrication-free iglidur® polymers
  • Smooth operation due to ball bearing
  • Upon request bearing spacing through flexible positioning of the individual hybrid roller bearings
  • Linear carriages in 3 lengths (100/150/200mm) by combination with WWYR mounting plates

Roller bearings from igus

Therefore we have developed the roller bearings WJRM-BB-31 & 41

The roller bearings WJRM-BB-31 & WJRM-BB-41 are designed to supplement our range of roller bearings.  
 
They manage to reduce the coefficient of friction by half and we are particularly proud to build such a robust yet lightweight roller bearing.  
 
We see these roller bearings especially in shop fittings,  trade fair construction, office organisation, furniture construction as well as media and event technology. Beyond that, however, there are of course no limits to its use.
