Metric TC Oil Seals | Simmerring® BASL Shaft Seals

BASL Oil Seals, also known as Simmerring® BASL radial shaft seals, are a premium sealing solution designed for rotating shafts where reliability and long service life matter. Built to DIN 3760 standards, these seals feature a spring-loaded primary sealing lip, a rubber-covered outer diameter for a secure housing fit, and an added dust lip to protect against external contamination. The BASL profile performs well in both dynamic and static conditions, handling mineral oils, greases, and many synthetic lubricants while compensating for thermal expansion and housing imperfections. For customers, this means fewer leaks, better equipment protection, and longer maintenance intervals, especially in gearboxes, axles, electric tools, and heavy equipment where uptime is critical.
