112x150x15 mm Truck Wheel Hub Oil Seal NBR, Double Lip Metal-Cased Rotary Shaft Seal for Axle Hubs

Product Overview

The VKEFOT 112 x 150 x 15 mm wheel hub oil seal is a metal-cased rotary shaft seal for truck and trailer axle hubs. It seals the hub bearing lubricant against the axle spindle and keeps road water, grit and mud out of the bearing cavity.

112 mm ID x 150 mm OD x 15 mm width · NBR (nitrile butadiene rubber) · double lip with garter spring · phosphated steel outer case with ribbed OD · DIN 3760 size 112x150x15.
VKEFOT Seals manufactures oil seals, O-rings and custom rubber parts in Xingtai, Hebei, China, and supplies fleet maintenance operations and parts distributors.

Key Features & Benefits

• Metal-cased outer diameter with ribs: the phosphated steel case, with its machined retaining ribs, bites into the hub bore for a firm interference fit. This is the right choice for a hub that sees heavy radial load and vibration, where a rubber-covered OD could creep.

• Double lip with dust lip: the main lip retains the bearing grease or oil; the secondary dust lip wipes the spindle and blocks water, grit and salt, which is the main cause of premature hub bearing failure on trucks working in mud or road salt.

• Garter spring on the main lip: a steel spring holds constant radial load on the spindle, so the lip keeps contact as the bearing warms up and as shaft run-out develops.

• Dimension-based replacement: matched to the DIN 3760 112x150x15 size, so it can be quoted directly against a measured spindle and hub bore without waiting for a vehicle identification.

• Bulk-ready packing: packed for workshop and distribution stock, so hub overhaul kits can be assembled without repacking.

Material & Construction

The seal combines a phosphated steel outer case with a moulded NBR sealing element. The case carries the press fit and provides rigidity under radial load; the outer diameter is machined with retaining ribs that resist rotation in the bore. The sealing element is a double lip design: a spring-loaded main lip for the lubricant side and a secondary dust lip that runs outboard to exclude contaminants.
For hubs that run hotter, use synthetic ester lubricants, or work in very low ambient temperatures, the same 112 x 150 x 15 mm geometry can be quoted in FKM/FPM or HNBR. Confirm the compound at the enquiry stage.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: case concentricity, lip geometry, spring seating and rib profile checked at set intervals.
• Final: dimensional check of ID, OD and width, hardness, visual inspection of the lip edge and marking, 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.

1. Size or reference: 112 x 150 x 15 mm, or the number stamped on your current seal.
2. Quantity and destination: required quantity, destination country and port.
3. Material requirement: NBR as standard, or FKM/HNBR for higher hub temperature or synthetic lubricants.
4. Packaging requirement: carton marks, label data, barcode requirement.
5. Measured dimensions or a sample: spindle diameter, hub bore and width if the part is not a standard catalogue size.
6. Operating conditions: lubricant type, hub temperature and road environment, if known.

Frequently Asked Questions

What are the exact dimensions of this oil seal?
Inner diameter 112 mm, outer diameter 150 mm, width 15 mm. Confirm against the measured spindle and hub bore before release.

What is the minimum order quantity?
State your required quantity and we will confirm the applicable MOQ with tiered pricing.

What is the lead time, and can you ship by sea or air?
Sea and air shipments are both arranged; freight and transit time are confirmed per order and destination.

Can you supply FKM or HNBR instead of NBR?
Yes. The same 112 x 150 x 15 mm geometry can be produced in FKM/FPM or HNBR where hub temperature or lubricant type exceeds the NBR range.

Do you provide samples, and are they free?
Samples can be arranged for evaluation. Sample cost and freight are confirmed during the quotation stage.

Can you produce our packaging and logo?

packaging and logo available upon request.

What information do you need to quote?
Size or stamped reference, quantity, destination port, material requirement and any packaging or marking specification. Measured spindle and bore dimensions help confirm suitability.
