CSB-LIN® Plastic linear bearings

Product properties

Maintenance free plastic linear bearings. Low noise operation is suitable for continuously application under the extremely dusty environment. It is washable by the clean detergent of the food machine. There is no critical requirement about the shaft hardness or the mounting holes of the housing.
● Maintenance-free, dry operation, low noise
● Suitable for long-time running in dusty environments
● Corrosion resistance; Cleaning with disinfectant
● Straight grooves design removes dust from the friction surface

▊CSB-LIN® linear bearings with high loading capability

As a linear sliding bearings, the contacting of the bearing and the shaft is a surface instead of point contact of the traditional ball bearings. So it results in that the surface contacting CSB-LIN® plastic linear bearings are with better loading capability than the sliding ball bearings.

▊CSB-LIN® linear bearings used in extremely conditions of sands and dusts

CSB-LIN® liners is made from high anti-wear material EPB13. The straight grooves design allows the bearing to be used in the extremely conditions such as in sands and dusts. The straight grooves design allows the sands or dusts entering the grooves and be brought out of the bearing system finally ,but the traditional ball bearings will be blocked by the entered sands or dusts, then the ball bearings moving system and the shaft surface will be damaged.

▊CSB-LIN® linear bearings operation with low noise

Metal ball bearings generates high noise by the crashing of balls to the shafts during the operation and the noise will be sharply increased when the operation speed goes higher while the CSB-LIN® plastic linear bearings are with the surface contacting structure which ensures a lower operation noise level.

▊CSB-LIN® linear bearings allows the access of cleaning solution

CSB-LIN® plastic linear bearings are used in the food packing machine guiding system so it is easily access to the cleaning solutions. Years of application experience proves that the CSB-LIN® plastic linear bearings are corrosion resistant to most kinds of Alkaline cleaning solutions or could be even immerged into the solutions.

▊CSB-LIN® 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.

CSB-LIN® Plastic Linear Bearings Finder V2.0

view tools

▊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.
