About this category

External retaining rings without lug holes - the outer edge is a continuous arc, so nothing protrudes to foul adjacent parts and the assembly looks cleaner. The number after the WR is the shaft diameter, so WR18 fits an 18 mm shaft.

How to choose

• Measure the shaft outside diameter, not inside the groove.
• With no lugs there are no plier holes, so fitting and removal differ from a standard S ring.
• The flush outer edge suits tight spaces and places where wiring could snag.
• As with S rings, go slightly smaller if the exact size is unavailable, never larger.
