13x25x7mm Oil Seal, Nitrile Rubber Rotary Shaft Seal, R21/SC,

Rotary shaft seals provide sealing and wiping functionality for rotating and swiveling movements under low pressure and high velocity. They perform two essential functions: the primary function is to retain the bearing or system lubricant in the system to avoid leakage, and the secondary function is to preclude any contamination of the system by external particles or other environmental factors. Radial shaft seals typically consist of a metal insert and an elastomer diaphragm with a spring-energised sealing lip.
