Definiton

MKC SEAL develops premium W-type wide-lip oil seals featuring a widened sealing surface and a reinforced spring engineered to deliver ultimate stability. This heavy-duty, high-vibration sealing lineage integrates industry-standard severe-duty profiles—including highly efficient scraper variants (WIPER) and outer metal-cased rigid configurations (WPB). By leveraging an enlarged contact area that effectively disperses frictional pressure and counteracts continuous shaft wobble or structural runout, this entire series guarantees exceptional fluid retention and aggressive external contaminant exclusion across vibrational heavy machinery, large hydraulic pumps, and truck transmission systems.

Applications

Applicable to vibrational heavy machinery, large hydraulic pumps, agricultural gearboxes and truck transmission systems. Performs excellently under medium speed with frequent vibration and minor shaft runout.

Selection Guide

Select according to shaft OD, housing ID and seal width. Confirm vibration intensity, working temperature, rotational speed and oil medium. MKC picks wear-resistant HNBR, oil-resistant FKM or standard NBR for vibrational heavy-load scenarios.

Materials

W wide-lip series supports wear & heat resistant rubbers: NBR, HNBR, ACM, VMQ, FKM and EPDM, specially optimized for equipment with vibration and slight shaft eccentricity.

Inquiry Info

Supply shaft dimension, housing size, seal width, material requirement, operating temperature, rotating speed, lubricant medium and order quantity. Mention vibration or shaft runout conditions for accurate matching.
