*) - Load capacity for the theoretical length of the cage of 100 mm with the thrust force "Fn" in accordance to the drawing.
- The load capacity is calculated for RWS1808 guides with hardness of 60 +/- 2 HRC and surface roughness of Ra<0.4. - Load capacity of bearing cages is calculated on the basis of number of bearing rollers mounted in the cage. - Length tolerance LK +0/-t; weight presented for the length of L=1000mm |
