Product Details

This bearing achieves the highest speeds, quietest and smoothest performance of all CSL products. This is because of the proprietary UTA Nano Technology which incorporates nano-sized particles of tungsten disulphide which is suspended into the EP liquid and impregnated into the CSL. It vastly increases service life due to its unprecedented ability to reduce wear caused by high speed, high loads and high temperatures. The unique size and shape of the nanomaterial used results in superior performance.


This bearing will have a tacky feel, a slightly stronger drag than the standard CSL model and will leave black residue on that hands but this is not harmful and is easily washed off. Using the CSL-EPN range in sub-zero temperatures or applications with extreme contamination is not advised.
