The CPC-AR15 Series Linear Guide Bearing Blocks are matched for the CPC-AR15N Series Rail. They are ideal for dynamic loads up to 9.0 kN （2020 lbs） and static loads up to 17.50 kN （3930 lbs） The design incorporates four rows of re-circulating steel balls arranged in the O-type design with a 45° contact angle with the raceway. The O-type design improves the rigidity of the track rail under moment and torsion forces. This series offers improved performance with larger diameter steel balls and an increased number of steel balls, which provides higher load capacities. Available in three lengths, （Short, Standard, or Long）, two end seals options （Standard or Reinforced）, and three preload classes （Standard, Light, or Medium）. Typically in stock in our Anaheim, CA warehouse.
