The Shaft Seal, wheel bearing (12693) keeps wheel bearing grease sealed and contaminants out of the hub assembly. Replacing a worn seal with Porza quality restores lubrication integrity and long-term driving safety.
A shaft seal for a wheel bearing is a sealing component installed between the rotating shaft and the bearing housing. Its function is to retain lubricant inside the bearing and prevent dirt, water, and contaminants from entering, which is essential to avoid premature bearing failure.
Key specifications include inner and outer diameter, thickness, material type (e.g. NBR, FPM, PTFE), and sealing lip design (single or double lip). Some seals include spring-loaded lips for improved sealing performance and durability under rotation and load.
Replacement is necessary when the seal is worn, cracked, hardened, or leaking. Common symptoms include grease or oil leakage, contamination inside the bearing, or noise during operation. It is recommended to replace the seal during bearing service.
