140x164x20 mm Truck Wheel Hub Oil Seal NBR, Metal-Cased Rotary Shaft Seal

Product Overview

A 140 x 164 x 20 mm truck wheel hub oil seal presses into the hub and runs on the spindle, keeping hub oil or bearing grease in and road water out. This one uses a metal case with a green coated outer diameter, a 20 mm body and a nitrile lip held by a garter spring.

At a glance:

140x164x20 mm | NBR (nitrile butadiene rubber) | single lip with a garter spring, metal-cased outer diameter with a green coating | made in Xingtai, Hebei, China | working range -30 C to +100 C (short peaks to +120 C)

VKEFOT produces this size in Xingtai, Hebei, China for fleets and axle workshops that service Volvo truck hub positions, and for wholesalers who stock by dimension. Measure the shaft, the housing bore and the depth on your own hub before ordering, because hub variants within one truck family do not always share a size.

Key Features & Benefits

• Green coated metal case: The case holds a true diameter through the press fit, so the seal stays square under wheel load, and the coating resists the water and road salt that reach a hub.
• Nitrile lip for hub oil: NBR is compounded for mineral hub oil and wheel bearing grease and keeps its sealing force across normal hub running temperatures.
• Spring-loaded lip: A garter spring maintains contact as the lip wears against the spindle, which is what keeps the hub dry between services.
• 20 mm body depth: The 20 mm case depth suits a hub counterbore deep enough to hold the seal square over the full width of the lip.
• For high mileage hubs: A truck hub sees constant dirt and heat, so an even press fit and the right case diameter are the difference between a dry hub and a repeat claim.
• Fitted on measurement: Selection is by shaft diameter, housing bore and depth, so compare against the seal you removed and check the spindle surface for a wear groove.

Dimensions are nominal production values, given as inner diameter x outer diameter x width. Check them against your own sample, or against a measured spindle and hub bore, before releasing an order.

Material & Construction

The lip is moulded from NBR (nitrile butadiene rubber), the standard compound for mineral hub oil and wheel bearing grease. It covers -30 C to +100 C (short peaks to +120 C) and keeps enough elasticity to follow a spindle with slight runout. The lip is bonded to a metal case with a green coated outer diameter and held on the spindle by a garter spring. Where a hub runs hotter, or the lubricant is a synthetic with aggressive additives, the same 140 x 164 x 20 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: case concentricity and coating, lip geometry, spring seating and the outer diameter grip checked at set intervals.
• Final: measured inner diameter, outer diameter and width, compound hardness, then a visual check on the lip edge, the case coating 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: 140 x 164 x 20 mm, or the number stamped 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 hub temperature or synthetic lubricant.
4. Marking and packaging requirement: label data, carton marks and barcode requirement.
5. Sample photo or drawing: where the part is matched from a worn original.
6. Operating conditions: hub oil or grease type, running temperature and shaft speed, if known.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Measure the spindle the seal runs on, the bore in the hub and the depth left in the hub, then compare the lip arrangement and the case with the seal you removed. Those three values decide the fit.

What are the exact dimensions of this oil seal?
140 mm inner diameter, 164 mm outer diameter and 20 mm width. Confirm them against your own sample or drawing, because hub counterbore depth differs between hub variants.

What is the minimum order quantity?
MOQ depends on whether 140x164x20 is held as a stocked size or made to order. Give your required quantity and we will confirm the MOQ and tiered pricing in the quotation.

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

Can you supply FKM or HNBR instead of NBR?
Yes. The same geometry can be produced in FKM (fluoroelastomer) or HNBR where the hub temperature or the lubricant is outside the NBR range. Confirm the compound at the enquiry stage.

Do you provide samples, and are they free?
Evaluation samples can be arranged. Sample cost and freight are quoted per request, and on a confirmed bulk order the sample charge is normally offset 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, lubricant type, running temperature, marking and packaging requirement, destination port and preferred Incoterm. A sample or a drawing gives the closest match.
