Selection guide
Selection Guide for Bulk Buyers 1. Confirm OEM cross reference number AZ9114520223, and verify shaft ID 160mm, housing OD 185mm, thickness 10.5mm and TC type double lip structure. 2. Standard NBR version for normal truck operating conditions ( 30℃ 120℃); select FKM upgrade for high temperature and special medium environments. 3. For fleet long term scheduled procurement, contact us for exclusive bulk pricing and dedicated supply schedule. Installation Steps Surface Preparation Thoroughly clean the balance shaft housing bore and shaft surface, remove old seal residue, carbon deposit, dirt and burrs. Pre lubrication Apply matching 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 external environment 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 rubber body directly to avoid seal deformation and lip tearing. Post installation Check Ensure the seal sits fully flush in the housing bore without tilt or offset. Inspect the sealing lip for nicks, scratches and deformation. Function Test Manually rotate the balance shaft to confirm smooth rotation without abnormal binding resistance.
