The main purpose of rotary shaft seals, commonly referred to as oil seals, is to safeguard and extend the longevity of bearing systems by eliminating the ingress of dust, dirt, water, and any other contaminants while preserving the lubricant .
An R21 type oil seal is characterised by a single lip design, featuring a rubber coating and a metal inner structure.
