Angular double-row bearing cages with bearing needles and positive control

 
Bin_1
 
Bin_2

Bearing cages with positive control (MVZ) offered by ROLLICO represent an innovative technical solution that prevents undesired dislocations of cages in linear guides.

Owing to application of toothed racks with modules of pinions embedded into ROLLICO bearing cages of the HW types, the set of MVZ prevents any unwanted lateral movements of cages between linear guides during operation.

Description:
Dimensions and properties of the HWMVZ bearing cages are identical as the ones of RW (HW)

Standard linear guides (e.g. "M" and "V") have been widened with the system of integral toothed rack that comprises the following components:

  • 2 guides (a top and a bottom one),
  • 2 toothed racks with appropriate module pitch,
  • 1 cage ROLLICO with a single or double set of toothed gears with an appropriate module pitch (depending on the cage length),
  • 2 or 4 end pieces with wipers and fixing bolts.
