Angular double-row bearing cages with bearing needles

     
 

  • Manufactured from profiles of light metals - aluminium (Al), brass (Ms) or steel (F)
  • High precision and strength at low deadweight (aluminium)
  • Destined for heavy-duty working conditions at high loads and accelerations
  • Working temperature up to 150°C
  • HW looks similar to H...ZW, however, cage sides are symmetrically bent at the right angle towards each other
  • Applicable areas include also linear guides of the types "M" and "V", "RM", "RV", "N" and "O"

*)  - Load capacity for the theoretical length of the cage of 100 mm with the thrust force "F" in accordance to the drawing.
     - The load capacity is calculated for guides with hardness of 60 +/- 2 HRc oand surface roughness of Ra<0,4.
     - Load capacity of bearing cages is calculated on the basis of number of bearing needles mounted in the cage
     - Length tolerance LK +0/-t
