Minimize fleet downtime and reduce Total Cost of Ownership (TCO) with PQK's engineering-grade National Truck Heavy Duty Wheel Hub Oil Seals. Built for extreme environments, our solutions are trusted by maintenance centers worldwide. As one of the premier oil seal suppliers, we deliver industrial reliability at scale.
The heavy-duty wheel hub oil seal is a critical dynamic sealing component designed for the axles of commercial national trucks and heavy equipment. Its primary function is to retain lubricating oil within the wheel hub assembly while simultaneously blocking external contaminants (mud, dust, water) from degrading the wheel bearings.
Manufactured with advanced NBR (Nitrile Butadiene Rubber) or FKM (Fluoroelastomer), these seals offer superior thermal stability (-40°C to +200°C) and wear resistance. For fleet operators, upgrading to these optimized multi-lip seals directly translates to extended maintenance intervals, prevention of brake failure caused by oil leakage, and overall improved fleet safety and operational efficiency.
Take a tour of our fully automated production lines. With an annual output of over 80 million units and TS16949 certification, we are a leading oil seal manufacturer committed to precision and scale.

"Since transitioning to PQK's FKM heavy-duty seals, our long-haul fleet has seen a 30% increase in maintenance intervals. The leakage issues on our rear axles have been completely resolved."
"As an OEM partner, we strictly audit our supply chain. Their IATF 16949 compliance, digital testing lab, and 50+ years of expertise make them a top-tier manufacturing partner for our truck axles."
"Consistent bulk supply, excellent dimensional tolerance, and a near-zero defect rate. They are undoubtedly one of the most reliable oil seal suppliers in the global aftermarket."
As a leading manufacturer, our standard Minimum Order Quantity (MOQ) is generally 500 pieces per model. However, we support mixed-model procurement for initial testing by fleet managers and maintenance centers.
With an annual production capacity exceeding 80 million units and fully automated assembly lines, our standard lead time for wholesale orders (e.g., a 20ft container) is typically 15-25 days.
Our facilities boast 54 years of manufacturing excellence and are certified with ISO 9001 and ISO/TS 16949 (IATF 16949) quality management systems, ensuring OEM-level reliability.
We utilize premium NBR and FKM (Fluoroelastomer) compounds specifically designed to withstand extreme heat generated by heavy braking, as well as resist tear and aging in muddy, off-road environments.
Our seals feature an optimized multi-lip design. The primary lip ensures tight oil retention on the axle, while the secondary dust lip prevents abrasives and moisture from entering, significantly reducing premature bearing failure.
