Dustproof design :  
                            The completely sealed design helps prevent dust ingress and reduce lubricant loss,  
                            which leads to extended service life. 
                             O-type arrangement : 
                              The 4-row re-circulating balls design helps achieve equal load capacity in all  
                              four directions. 
                             Patented design for high speed/impact :  
                              The L-shaped stainless-steel reinforcement plates with bottom latches help cover and  
                              strengthen the end caps, allowing high-speed/impact operations.
