Question by: Patty R on Mar 14, 2026, 5:52 PM

Got a 5-inch shaft I need to retain on some farm equipment, this the right ring for that application?

Answer by: Customer Support on Mar 16, 2026, 3:00 PM

For a 5-inch shaft diameter, this is the correct fit. The ring is spec'd with a shaft diameter of 5 inches and a groove diameter of 4.79 inches, so it seats properly in the groove without slop. The 0.25-inch radial wall gives it enough surface contact to hold position under load, and the spiral external design means it goes on from the outside of the shaft rather than into a bore.

What size shaft does this retainer ring work best with?

This ring is really designed for shafts that are about 5 inches in diameter, that's where you'll get the best fit.
