EPR I-Beam Connecting Rods

EPR Series are BW flagship series.

In 2010, BW introduced the EPR flagship series. It’s a brand new designed I-Beam. Over the last decade, BW had made numerous developments and improvements. Now it features more advanced technologies with no additional cost. The EPR series I-Beam is designed for applications where rod strength is the priority concern. EPR I-Beam rods minimized the total weight, featuring following advantages:

  • Ribbed pin mass
  • Oil slot on BE surface
  • Stronger beam design
  • Special surface treatment
