Snap Ring vs. E-Ring
Snap Ring vs. E-Ring
(OP)
Hi everyone. I'm new here, but it looks like a solid forum. I'm trying to decide which retaining ring to use in a design, snap ring or E-ring. It is for a 3/8 pin that acts as a pivot point for a angled bar attached to a 27 lbf linear actuator, creating 54 in-lb of torque. Again, it is the pivot point. I would use two grooves; one to hold the pin and angled bar together, and one to hold the end of the pin to an 8 gauge steel plate. Any ideas? I'm new to this ring application, so I'm still fuzzy on the advantages and disadvantages of each type of external ring. Thanks in advance.

Since the load is not high, I would go with the easier of the two to maintain.

The only advantage with E-rings is that they are easier to install. But E-rings normally require more radial clearance to install than snap rings.
Installing a thrust washer between the retaining ring and its mating part will also help if there is relative motion at the thrust face of the retaining ring.
Hope that helps.
