Product details

This 58×70×7.5/7mm oil seal is a general purpose rotary shaft sealing solution for industrial and light automotive scenarios, mainly used for radial sealing of rotating shafts in equipment such as industrial motors, centrifugal pumps, reducers and agricultural machinery. It adopts TB type exposed metal case structure, which provides reliable press fit positioning in the housing bore and resists radial displacement under vibration conditions. The precision machined NBR sealing lip, matched with a carbon steel garter spring, maintains stable radial contact pressure on the shaft surface, effectively blocking lubricating oil leakage inside the equipment and preventing external dust, water mist and impurities from invading the bearing chamber. This size is a common general specification in the industrial field, interchangeable with oil seals of the same size from mainstream brands. It is suitable for both OEM supporting of small and medium sized equipment and aftermarket maintenance replacement. We maintain long term stable stock of conventional sizes to meet the needs of bulk procurement and urgent maintenance. Core value for buyers Universal industrial size, widely compatible with motors, pumps, reducers and other equipment Stable sealing performance under medium speed and medium load working conditions Mature production technology, stable batch quality, cost effective for bulk use Fast delivery from stock, supporting small batch trial and large batch replenishment

Material and process

Material ：Premium grade NBR (nitrile butadiene rubber) sealing lip, cold rolled steel outer case, carbon steel garter spring Structure ：TB type single lip exposed metal case rotary shaft oil seal Hardness ：70±5 Shore A Key performance ：Oil resistant, wear resistant, dust proof, anti aging Working temperature range: 30℃ +120℃ (standard NBR 70) Working speed ：≤12 m/s (medium speed condition) Manufacturing process Integrated vulcanization bonding between rubber lip and metal case Precision trimming of sealing lip edge for uniform contact pressure Dimensional inspection per production batch before shipment Quality control aligned with general industrial sealing standards Upgrade option ：FKM (fluoroelastomer) version available for higher temperature and chemical resistance requirements

Application and compatibility

Product Type ：General industrial rotary shaft oil seal Core dimensions ：ID 58mm × OD 70mm, thickness 7.5mm / 7mm Compatible fluids: Mechanical lubricating oil, bearing grease, hydraulic oil, gear oil Typical application scenarios: Industrial AC/DC motor output shaft sealing Centrifugal pump, water pump shaft sealing Gear reducer, gearbox auxiliary shaft sealing Agricultural machinery rotating shaft sealing Automotive steering system, transmission auxiliary shaft sealing General mechanical equipment bearing housing sealing Suitable for ：Industrial parts distributors, equipment maintenance service providers, agricultural machinery repair shops, auto parts distributors, small equipment OEM factories Buyer notice ：This is a standard universal size aftermarket replacement part. Please confirm shaft diameter, housing bore size and installation space before ordering. Dimension mismatch will cause lubricant leakage after installation.

Selection guide

Selection Guide 1. Confirm shaft diameter 58mm, housing bore 70mm, installation depth 7.5/7mm, and select TB type for exposed housing bore scenarios. 2. Standard NBR version is recommended for conventional mineral oil lubrication and working temperature 30℃ 120℃; select FKM upgrade for high temperature or strong chemical media. 3. For equipment with large vibration or heavy dust, it is recommended to select double lip structure products. Installation Steps Surface Preparation Thoroughly clean the installation housing bore and shaft surface, remove burrs, dirt, old seal residue and impurities. Pre lubrication Apply compatible lubricating oil or grease evenly on the sealing lip and shaft surface to avoid lip cutting during installation. Installation Press the seal into the housing bore evenly with a dedicated installation tool, keep it perpendicular to the shaft. Avoid hitting the seal directly with hard tools. Post installation Check Confirm the seal is properly seated in the groove without tilting, and the sealing lip is not twisted or damaged.
