This 190×232×30mm TB type oil seal is a high performance aftermarket sealing solution for commercial vehicle wheel hub and drive axle systems, widely applied in heavy duty truck chassis and rotating shaft components. It adopts an exposed steel outer case for rigid mounting and structural stability, paired with precision machined primary oil sealing lip and secondary dust proof lip. A built in carbon steel garter spring maintains consistent radial preload on the shaft surface, even under heavy load vibration and road impact. The inner lip retains hub gear oil and bearing grease inside the assembly, while the outer lip blocks road dust, mud, grit and splash water from invading the bearing chamber, effectively extending the service life of hub bearings and shaft parts. Produced with strict dimensional tolerance control, it matches standard industry size specifications and can be directly installed without modification. We maintain stable finished goods inventory to support fast delivery and large volume procurement for global automotive aftermarket channels. Core value for buyers Standard interchangeable dimensions, direct drop in replacement for auto repair Metal case structure for stable mounting and reliable sealing performance Factory direct pricing, cost effective for bulk sourcing and repair shops Consistent batch quality, suitable for long term scheduled replenishment

Selection guide
Selection Guide 1. Confirm shaft ID 190mm, housing OD 232mm, required thickness 30mm and TB metal case double lip structure. 2. Standard NBR version for normal automotive operating conditions ( 30℃ 120℃); select FKM upgrade for high temperature and chemically aggressive environments. 3. For bulk repair or fleet maintenance projects, contact us for exclusive volume pricing. Installation Steps Surface Preparation Thoroughly clean the hub housing bore and shaft surface, remove old seal residue, dirt, rust and metal burrs. Pre lubrication Apply matching bearing grease or gear oil evenly on the sealing lip and shaft mating surface. Dry installation is strictly prohibited as it will cause premature lip wear and failure. Orientation Confirmation The main sealing lip faces the lubricant cavity side; the dust proof lip faces the wheel outer side. Reverse installation will cause oil leakage and loss of dust protection. Press fit Installation Use a dedicated press sleeve tool to press the seal in evenly and vertically. Never strike the metal case directly to avoid seal deformation and lip tearing. Post installation Check Ensure the seal sits fully flush inside the housing bore without tilt or offset. Inspect the sealing lip for nicks, scratches and deformation. Function Test Manually rotate the wheel hub assembly to confirm smooth rotation without abnormal binding resistance.
