Selection guide
Selection Guide 1. Confirm OEM cross reference number DZ90129340063, and verify shaft ID 185mm, housing OD 210mm, thickness 22mm and TC double lip structure. 2. Standard NBR version for normal truck operating conditions ( 30℃ 120℃); select FKM upgrade for high temperature and chemically aggressive environments. 3. For long term fleet procurement projects, contact us for exclusive bulk pricing and dedicated supply schedule. Installation Steps Surface Preparation Thoroughly clean the rear hub housing bore and shaft surface, remove old seal residue, dirt, rust and metal burrs. Pre lubrication Apply matching hub gear oil or bearing grease 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 mud protection. Press fit Installation Use a dedicated press sleeve tool to press the seal in evenly and vertically. Never strike the rubber body 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.
