The ER industrial series, relubricatable type ball house unit incorporates (optional) Shaft Guard Technology, which reduces replacement time, provides shaft protection and prolongs shaft life.
Strengths
Test results indicate an average of 95 percent reduction in start-up torque when using ER-DD instead of the standard ER bearing.; Running torque is reduced up to 85-90 percent.
Applications
This bearing is designed for use in applications where low-starting torque and low-running torque are necessary.; The ER-DD series is for applications where extremely low torque is required.
