Speared Ends External Retaining Rings
Often used with small engines, heavy equipment, and power transmission, these external retaining rings have speared ends to help you install and remove them. They’re constant-section style, which means the distance between their inside and outside diameter is consistent, so the clearance around their circumference doesn’t change either. All are made of spring steel for good strength and reliability. To resist corrosion in dry environments, they’re oil coated.
