SR-EM-R Shaft Rings
Product Description
Axially Assembled, External Reinforced, Metric
The SR-EM-R is an extra thick version of a regular SR-EM retaining ring. As such, it is stronger and can withstand greater thrust loads than its standard counterpart.
For plated rings, add 0.05 to the listed maximum thickness. Maximum ring thickness will be a minimum of 0.005 less than the listed groove width (W) minimum. All dimensions in millimetres
