CSB-LIN® Precision linear bearings

Product properties

LINP precision linear bearings have the same dimensional accuracy as metal ball linear bearings, but with higher load carrying capacity and extremely low operating noise. The liners are made of TEFPLASTM compounds developed for maintenance-free and low friction coefficient, LINP linear bearings suitable for ± 200 ℃ operation temperature; LINP small gap operation with  TEFPLASTM materials will not damage to the shaft and can clean the surface dirt.
●Self-lubricating, maintenance-free
●High precision and smooth operation
●Vibration reduction, no noise
●High-speed operation and long life

***For operation under extreme high temperature, it is necessary to consider increasing the fitting clearance to avoid stagnation caused by the high temperature expansion of the shaft and bearing. Please contact us.

CSB-LIN® P Chemical resistance

TEFPLASTM materials stand up to harsh environments and provide excellent performance in a submerged condition. TEFPLASTM B: the fillers in the material can be attacked by deionized water and other harsh chemicals.
TEFPLASTM G and TEFPLASTM E : almost universal chemical inertness.
The standard shell material is anodized aluminum of CSB-LIN® P precision linear bearings: good chemical resistance in most industrial applications, 316 stainless steel shell are available for corrosion resistance in harsh environments

CSB-LIN® P Factors affecting wear rate and life

Affecting the life of CSB-LIN®P precision linear bearings: surface roughness, hardness and dimensional accuracy of the shaft
Recommend shafts for the best performance:
 ●Shaft diameter tolerance h6-h7, suitable for all TEFPLASTM materials
 ●Surface roughness Ra0.2-0.4, suitable for all TEFPLASTM materials
 ●Surface hardness HRC50, according to different TEFPLASTM materials and the soft shafts are available

CSB-LIN®P Eccentric forces

●Maximum 2:1 ratio
●1x =bearing separation on same shaft
●2x =distance from shaft to load or force

CSB-LIN® Precision linear bearings

 ●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 used! The greater the distance between the drive and guide bearings, the higher the degree of wear and required drive force.
There may be other factors that add to the braking effect, but the coefficient of friction is the main cause.
NOTE: The Rule(2:1) is based on the static friction value of 0.25 theoretically, However, Additional lubrication can help to drop friction and extend the 2:1 ratio.
If you have any questions on design and/or assembly, please contact our application engineers.

CSB-LIN® Plastic Linear Bearings Finder[V2.0] including LIN plastic linear bearings and LINP precision linear bearings. The system is based on the analysis and calculation of a large number of test data in CSB laboratory. You can calculations bearing data by entering parameters such as bearing load, speed, temperature and position information, The system will output bearing adaptation data and min. driving force.
Because the system calculate and analyze based on lab data, it can't exactly meet the ractual use requirements absolutly. The system data verification has certain limitations; CSB recommends that the bearing must be tested again to verify whether it meets the actual use requirements.
CSB-LIN® Plastic Linear Bearings Finder output data information is only for design reference, and can not be used as the final standard for determining the bearing material conformity, If you have any questions, please contact CSB sales engineers.
