SC Oil Seal is a spring-loaded single-lip shaft seal with integrated metal skeleton. Its built-in stainless steel spring keeps the lip closely fitted to shafts to stop oil leakage. Made of NBR/FKM/CR rubber vulcanized with cold-rolled steel, it features low friction and stable sealing at medium speed. Compact and cost-effective, it fits light & medium-load machinery like farm equipment, small loaders and water pumps for normal dusty conditions.
Key Features
Full rubber covered outer diameter design, effectively stopping circumferential leakage between seal and housing bore
Spring pre-tightened primary lip maintains consistent clamping force for reliable lubricant retention
Independent auxiliary dust lip reduces external dirt ingress and slows main lip abrasion
Two material options to cover regular temperature and high-temperature operating scenarios
Compact integrated single skeleton structure, easy mass assembly for standardized machinery
