132x179.5/214x30.5 mm Truck Wheel Hub Oil Seal BZ5942E NBR, Flanged Rotary Shaft Seal

Product Overview

A 132 x 179.5 x 30.5 mm flanged hub seal is bolted to the hub or axle end instead of being pressed into a bore. The 214 mm flange carries the mounting holes, and the rubber lip seals on the 132 mm shaft, so a wheel end can be resealed without re-machining the housing.

At a glance:

132x179.5/214x30.5 mm | NBR (nitrile butadiene rubber) | single lip with a garter spring, rubber lip in a steel flange with mounting holes | made in Xingtai, Hebei, China | working range -30 C to +100 C (short peaks to +120 C)

VKEFOT builds this size in Xingtai, Hebei, China for truck fleets and axle workshops that replace hub seals on a mileage schedule, and for wholesalers who stock by dimension. Compare the flange hole pattern, the flange thickness and the 132 mm shaft with your own hub before ordering.

Key Features & Benefits

• Bolted flange instead of a press fit: The flange locates on the hub face and is held by its mounting holes, so a worn or slightly oversized bore does not condemn the hub when the seal is renewed.
• Wide 214 mm flange: The flange gives a large bolted contact area, which keeps the seal square to the shaft and resists tilting under wheel load.
• Nitrile lip on a 132 mm shaft: The rubber lip is compounded for axle oil and wheel bearing grease and keeps its grip on the shaft across the service interval.
• Spring-loaded contact: A garter spring keeps the lip pressed against the shaft, taking up wear so sealing force does not fall away as the hub runs.
• 30.5 mm flange depth: The deep body keeps the lip supported over the full flange thickness and suits hub ends where a thin seal would sit too far back from the shaft shoulder.
• Suits planned wheel-end work: Because the flange is bolted, a swap is quick and repeatable, which suits workshops that service wheel ends on a fixed cycle.

Dimensions are nominal production values: 132 mm inner diameter, 179.5 mm seal outer diameter, 214 mm flange diameter and 30.5 mm flange thickness. Check the flange hole pattern and both diameters against your own hub before releasing an order.

Material & Construction

The lip is moulded from NBR (nitrile butadiene rubber) and bonded into a steel flange, which is the usual arrangement where a hub seal is bolted rather than pressed in. NBR resists axle oil and wheel bearing grease and covers -30 C to +100 C (short peaks to +120 C), with enough elasticity to follow a shaft with slight runout. The lip is held against the shaft by a garter spring. If the wheel end runs hotter or uses a synthetic lubricant, the same 132 x 179.5/214 x 30.5 geometry can be quoted in FKM (fluoroelastomer, also written FPM), which holds continuous duty to about +200 C.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: flange flatness and hole pattern, rubber-to-flange bond, lip geometry and spring seating checked at set intervals.
• Final: measured inner diameter, seal outer diameter, flange diameter and flange thickness, compound hardness, then a visual check on the lip edge and the 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.

Packaging, Carton and Delivery

Standard packing is individual polybag, inner carton, then export carton. Carton marks, labels and barcodes are printed to buyer specification.

Lead time for standard sizes is typically 7 to 15 working days after order confirmation, and longer for sizes that are not held as standard stock. Minimum order quantity depends on whether the size is a stocked standard or made to order. Pricing, MOQ, freight and trade terms are confirmed in the written quotation. Send an RFQ with quantity and destination port.

How to Order

The more of this you include, the faster and more accurate the quotation:

1. Size or OE number: 132 x 179.5/214 x 30.5 mm, or the number on the seal you are replacing.
2. Quantity and destination: required quantity, destination country and port.
3. Material requirement: NBR as standard, or FKM for higher wheel-end temperature or synthetic lubricant.
4. Marking and packaging requirement: label data, carton marks and barcode requirement.
5. Sample photo or drawing: a hub flange drawing or a photo of the old seal, so the hole pattern can be matched.
6. Operating conditions: axle oil type, running temperature and shaft speed, if known.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Measure the shaft, confirm the flange diameter and the hole pattern against your hub face, and check the flange thickness clears the hub. The seal is bolted, so the hole pattern matters as much as the bore.

What are the exact dimensions of this oil seal?
132 mm inner diameter, 179.5 mm seal outer diameter, 214 mm flange diameter and 30.5 mm flange thickness. Confirm the flange measurements against your own hub before ordering.

What is the minimum order quantity?
MOQ depends on whether this size is held as a stocked standard or made to order. Tell us the quantity you need and we will confirm the MOQ with tiered pricing in the quotation.

What is the lead time, and can you ship by sea or air?
Stocked sizes normally ship within 7 to 15 working days after order confirmation, and longer for sizes that are not held. Sea and air freight are both arranged, with freight and transit time confirmed per destination.

Can you supply FKM or HNBR instead of NBR?
Yes. The same flange and lip geometry can be produced in FKM (fluoroelastomer) or HNBR where the wheel-end temperature or the lubricant calls for it. Confirm the compound when you enquire.

Do you provide samples, and are they free?
Samples can be arranged for evaluation. The sample and its freight are quoted per request; on a confirmed bulk order the sample charge is normally set off against the order value.

Can you produce our packaging and logo?
packaging and logo available upon request.

What information do you need to quote?
The size or the number on your old seal, quantity, flange hole pattern or a photo of the hub, material, working temperature, packaging requirement, destination port and preferred Incoterm.
