FAQ

Q: What kind of shaft can this seal be used on?
A: It works on shafts with 14 mm diameter, typically crankshafts, gearbox shafts, pump shafts, and other rotating elements requiring oil sealing.

Q: Why choose NBR material for the seal?
A: NBR offers strong resistance to oils, greases, fuels, and hydraulic fluids while maintaining elasticity — ideal for automotive and industrial oil-seal applications.

Q: Is the CORTECO 12011750 suitable for high-speed rotation?
A: Yes — the seal’s construction and NBR compound allow it to operate reliably under moderate to high rotational speeds, provided shaft and housing tolerances are respected.

Q: Can this seal handle harsh industrial environments?
A: Yes — thanks to its resistance to oil, grease, chemical contact and rotational wear, it is suitable for industrial machinery, hydraulic units, and frequent-use applications.

Q: How to verify correct sizing before installation?
A: Check both shaft diameter and housing bore diameter. Ensure they match 14 mm (shaft) and 28 mm (bore) respectively, with 7 mm width clearance for proper sealing and fit.
