TB 140x160x10mm Metal Cased Oil Seal NBR Brown | Automotive Mudproof Wheel Hub Seal

This aftermarket TB metal cased double lip oil seal measures 140mm ID, 160mm OD and 10mm in height, manufactured with brown NBR rubber and a rigid outer iron shell. It is engineered for mudproof and leakproof performance in automotive wheel hub and repair applications.

Importers, wholesalers, auto repair shops and MRO distributors can submit RFQ with dimension, quantity, destination and working medium for a formal quotation. Lead Time: 7–15 days for standard production.

Features & Benefits

Rigid outer iron shell delivers stable press fit in the housing bore, resists radial distortion and prevents seal rotation under road vibration and dynamic loads.
Double lip design with a single garter spring maintains consistent radial contact pressure on the shaft. Primary lip retains lubricant; secondary lip blocks road mud, dust and splash water for mudproof performance.
Brown NBR nitrile rubber lip offers good compatibility with mineral wheel bearing greases and gear oils, with balanced wear resistance for typical on-road duty cycles.
Precision finished metal outer diameter ensures reliable static sealing between seal and housing, compensates for minor bore tolerances and surface imperfections.
Standard metric dimensions match common TB-type housing specifications, suitable for direct aftermarket replacement in most standard wheel hub assemblies.
This is an aftermarket replacement seal, not a genuine OEM part. Always verify shaft diameter, housing bore and application before ordering.

Aftermarket replacement. Verify shaft diameter, housing bore and application before order.

Selection & Installation

Selection Tips

Confirm shaft ID 140mm, housing OD 160mm, seal height 10mm. Choose NBR compound for standard temperature mineral lubricant applications.

Installation Steps

1. Thoroughly clean the shaft and housing bore. Remove all burrs, old seal residue, rust and contamination.
2. Lightly lubricate the sealing lip and shaft with the same grease or oil used in the assembly. Do not install dry.
3. Press the seal evenly into the housing using a proper installation tool. Keep the seal perfectly perpendicular to the bore.
4. Do not strike the rubber lip or hammer directly on the metal shell edge. Avoid cocking or distorting the seal.
5. After assembly, rotate the hub by hand to check for binding. Inspect for leakage during initial test run.
