Product details
VKEFOT TB type 65x90x13 mm radial rotary shaft oil seal manufactured in Xingtai, China. TB is ISO Type5 flanged metal skeleton oil seal. The rigid flanged carbon steel outer shell delivers stable axial positioning and strong anti-deformation performance during assembly.
This crankshaft rear oil seal adopts double lip construction. The main sealing lip retains engine oil inside the crankcase, while the secondary dust lip blocks dirt, mud and splash water from entering the engine. Made from NBR nitrile rubber, it offers good oil resistance and wear resistance. Max working pressure ≤0.05MPa, allowable shaft speed up to 12m/s, operating temperature -35℃ to +100℃. Widely used as aftermarket replacement for automotive engine crankshaft rear shaft overhaul.
Key Features
- TB ISO Type5 flanged metal shell radial shaft oil seal, dimension 65×90×13 mm
- Rigid AISI1010 carbon steel flange housing, anti-deformation
- Double lip design: main sealing lip + dust lip for dual protection
- NBR nitrile rubber, good oil resistance and wear resistance
- Aftermarket replacement for automotive crankshaft rear shaft sealing
Material & Working Condition
Base rubber material is NBR (Nitrile Butadiene Rubber). Compatible with mineral oils and greases. Not suitable for ester oils, brake fluid and strong chemical solvents. Confirm lubricant type and operating temperature in your RFQ.
Typical Applications
Automotive engine crankshaft rear shaft sealing. This is an aftermarket replacement seal. Verify shaft diameter and housing bore dimension before purchase.
Installation Guide
- Clean shaft journal and housing bore thoroughly, remove old seal residue, rust, burrs and contaminants.
- Lightly lubricate sealing lip with compatible oil or grease before fitting.
- Press TB seal evenly and squarely into the bore until flange face fully sits against housing surface, avoid tilting.
