Flat double-row bearing cages with bearing rollers

Manufactured from profiles of light metals - aluminium (Al)_x with polyamide inserts
High precision and strength at low deadweight (aluminium)
Destined for heavy-duty working conditions at high loads and accelerations
Working temperature up to 120°C

*) - 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 L_K +0/-t
