Product details
Product Overview
A 91x111x9 mm wheel hub oil seal is a radial shaft lip seal pressed into the hub or axle housing; it holds wheel bearing grease or axle oil in the bearing and stops water, mud and road dirt from reaching it. This one is a TC profile in NBR (nitrile butadiene rubber): rubber-covered outer diameter with a spring-loaded main sealing lip and a secondary dust lip.
VKEFOT builds this size in Xingtai, Hebei, China for distributors, fleet operators and repair programmes that buy by dimension. The fit is decided by three measurements taken from your sample: shaft diameter, housing bore and available width.
Key Features & Benefits
TC profile: Rubber-covered outer diameter with a spring-loaded main sealing lip and a secondary dust lip.
Metal case for press fit: The case holds its diameter in the bore, so the seal stays square and does not walk out under load and vibration.

Dimensions are nominal production values measured as inner diameter x outer diameter x width. Where two widths are quoted, the first is the lip section and the second is the overall body - measure both on your sample before ordering.
Material & Construction
The sealing element is moulded from NBR (nitrile butadiene rubber), the general-purpose lip material for oil and grease service. The body is bonded to a metal case and the main lip is held on the shaft by a garter spring. Construction: rubber-covered outer diameter with a spring-loaded main sealing lip and a secondary dust lip.
Quality Control and Inspection
- Incoming: compound hardness checked before release to production.
- In process: lip geometry, case outside diameter and spring fit checked at set intervals.
- Final: dimensions are checked against the nominal size and the lip is inspected for cuts, flash and spring seating, then packing count verification.
- Traceability: inspection results for each batch are recorded and kept; the inspection scope can be agreed before order confirmation.
Buyers are welcome to arrange third-party inspection before shipment; state the requirement in the enquiry so it can be built into the quotation.
