Oil Seals
Overview
Oil seals (rotary shaft lip seals) are key components preventing lubricant leakage and ingress of contaminants, widely used in gearboxes, hydraulic motors, engine crankshafts and hubs. Our oil seals cover NBR, FKM/Viton, silicone (VMQ) and PTFE for different temperatures, media and speeds.
Features
- NBR: oil- and wear-resistant, temperature range -30 C to +120 C
- FKM: high-temperature and chemical resistant, temperature range -20 C to +250 C
- Double-lip design: main lip seals oil, auxiliary lip keeps dust out
- Spring-loaded lip for constant radial force and more reliable sealing
Applications
Hydraulic cylinder rod seals, hydraulic motor shaft seals, gearbox input/output shaft seals, engine crankshaft front/rear seals and hub bearing seals.
Key Advantages
Full material range for different conditions; comprehensive sizes with outer diameters 10-1000 mm; various structures including framed, frameless and externally threaded seals.
