| Precision Shafts Information |
Information as follow:
● AS: Hard anodized aluminum shaft, the best shaft for CSB-LIN® linear bearings
● CS: Hard-chromed steel shaft, the effective-cost shaft
● ES: #304 Stainless steel shaft, the best choice for chemical liquid Application
● Shaft end processing service is available
Precision aluminum shafts Precision steel shafts Precision stainless steel shafts Shaft end blocks
All the three shafts are available. Please check the shaft lengths that you need. There are different size of diameters: 6/8/10/12/16/20/25/30mm, can meet different requirments for applications. The tolerances of different shaft are different, too. Choose the best product can offer a better operating performance.
| Factors Affecting Life |
Affecting the life of CSB-LIN® P precision linear bearings are: surface roughness, hardness and dimensional accuracy of shafts.
We recommend to use the shafts as below for the best performance:
• Shaft diameter tolerance h6~h7, suitable for all TEFPLASTM materials
• Surface roughness Ra0.2~0.4μm, suitable for all TEFPLASTM materials
• Surface hardness HRC50, according to different TEFPLASTM materials and the soft shafts are available
| Eccentric Force |
Maximum 2:1 ratio
1x = bearing separation on same shaft
2x = distance from shaft to load or force
CAUTION: uneven motion or even system blockage will occur if the 2:1 ratio is exceeded!
This principle is NOT load dependent! It is NOT due to edge loading. It is also NOT dependent on the driving force that used! The greater the distance between the drive and guide bearings, the higher the required drive force and the degree of wear.
NOTE: The Rule(2:1) is based on the static friction value of 0.25 theoretically, however, additional lubrication can help to drop down the friction and extend the 2:1 ratio.
