80x100x10 mm Rotary Shaft Oil Seal NBR, Brown Metal-Cased Lip Seal

Product Overview

An 80 x 100 x 10 mm lip seal closes the gap between an 80 mm shaft and a 100 mm housing bore. It keeps gear oil or grease inside the unit and stops dirt and water entering along the shaft.

At a glance:

80x100x10 mm | NBR (nitrile butadiene rubber) | single lip, garter spring, metal-cased body | made in Xingtai, Hebei, China | working range -30 C to +100 C (short peaks to +120 C)

The brown NBR lip is moulded over a steel case and held against the shaft by a garter spring. Round decimal free sizes like this one appear on axles, hubs, reducers and pump shafts, so buyers normally specify it from measurement.

Key Features & Benefits

• Brown nitrile lip: NBR in this grade handles mineral and gear oils, keeps its shape in service, and works down to about -30 C without stiffening.
• Spring gives constant contact: The garter spring keeps the lip against the shaft as it beds in, which is what holds a slow leak back over a long service interval.
• Case takes the press load: The steel case absorbs the fitting force and keeps the outer diameter round, so the lip is not distorted during installation.
• Handles dirty surroundings: A tight bore seat and a closed lip line keep dust and water out on axles and hubs that see road or site conditions.
• Works on worn shafts: NBR flexibility and spring load together tolerate light scoring and a slightly out of round shaft, which suits repair work.
• Single operation fitting: Drive the seal in square until the face is flush, and the joint is ready without sealant or heat.

Dimensions are nominal production values listed as inner diameter x outer diameter x width. Compare them with the removed part or a measured shaft and housing bore before ordering.

Material & Construction

The lip and outer moulding are NBR (nitrile butadiene rubber), the standard compound for oil and grease sealing on shafts. It covers -30 C to +100 C with short peaks to +120 C, resists mineral and gear oil, and keeps enough give to follow a shaft that is slightly off centre. A steel case carries the press fit and a garter spring loads the lip. Where the unit runs hotter or uses synthetic lubricant, the same 80 x 100 x 10 seal can be produced in FKM, which holds continuous duty to about +200 C.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: case concentricity, lip geometry, spring seating and outer diameter roundness checked at set intervals.
• Final: inner diameter, outer diameter and width gauging, rubber hardness, lip edge and marking check, then packing count verification.
• Traceability: inspection results for each batch are recorded and kept; the inspection scope can be agreed before order confirmation.

Third party inspection before shipment can be arranged on request; name it in the enquiry so it is included in 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: 80 x 100 x 10 mm, or the measurement taken from the old seal.
2. Quantity and destination: pieces needed, destination country and port.
3. Material: NBR as standard, or FKM where heat or synthetic fluid requires it.
4. Marking and packaging: print on the seal and carton labelling details.
5. Sample or drawing: send one where the dimensions come from a used part.
6. Working conditions: temperature, lubricant and shaft speed, if known.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Measure shaft diameter, housing bore and the space available for the seal. Readings of 80 mm, 100 mm and 10 mm identify this size; then match the lip compound to the oil and temperature.

What are the exact dimensions of this oil seal?
80 mm inner diameter, 100 mm outer diameter and 10 mm width. Treat them as nominal and check them against your own part or drawing before an order is placed.

What is the minimum order quantity?
It depends on whether 80 x 100 x 10 is a stock size or has to be run for you. State the quantity you expect to order and the quotation will confirm the MOQ and pricing tiers.

What is the lead time, and can you ship by sea or air?
Standard sizes normally ship within 7 to 15 working days after order confirmation. Sea and air shipments are both arranged, with cost and transit time quoted for your destination.

Can you supply FKM or HNBR instead of NBR?
Yes. FKM raises the continuous limit to roughly +200 C and improves resistance to synthetic fluids; HNBR helps where abrasion and ozone attack the seal. Confirm the compound when you enquire.

Do you provide samples, and are they free?
Samples can be provided for evaluation. Sample and freight charges are quoted per request, and on a confirmed bulk order the sample cost is normally credited.

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

What information do you need to quote?
Size or a photo of the seal being replaced, quantity, material, working temperature and fluid, marking and packing requirements, and the destination port.
