Flat 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

*) - 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 |
