TB 98x113x12mm Metal Cased Double Lip Oil Seal NBR | Automotive Wheel Hub Seal

This aftermarket TB metal cased double lip oil seal measures 98mm ID, 113mm OD and 12mm in height, manufactured with brown NBR rubber and a rigid steel outer case. It is designed for reliable sealing in automotive wheel hub and heavy rotary shaft 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 steel outer case delivers stable press fit in the housing bore, resists radial distortion and prevents seal rotation under vibration and dynamic loads.
Double lip design with a single garter spring maintains consistent radial contact pressure on the shaft. Primary lip retains oil and grease; secondary lip blocks dust, splash water and light contaminants.
Brown NBR nitrile rubber lip offers excellent compatibility with mineral oils, wheel bearing greases and standard hydraulic fluids, with balanced wear resistance for typical 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 assemblies.
This is an aftermarket replacement seal, not a genuine OEM part. Always verify shaft diameter, housing bore and application before ordering.

Selection & Installation

Selection Tips

Confirm shaft ID 98mm, housing OD 113mm, seal height 12mm. Match rubber material to your lubricant type and operating temperature range.

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 oil or grease 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 case edge. Avoid cocking or distorting the seal.
5. After assembly, rotate the shaft by hand to check for binding. Inspect for leakage during initial test run.
