44x62x9 mm Rotary Shaft Oil Seal NBR, TC Type Shaft Seal with Metal Insert

Product Overview

A 44 mm shaft in a 62 mm bore with a 9 mm body: a compact seal with a narrow radial band, often found on pump shafts, transmission covers and small axle ends. Space is limited around the shaft, so the seal has to be concentric to work properly.

At a glance:

44x62x9 mm | NBR (nitrile butadiene rubber) | double lip TC body with bonded metal insert, garter spring and ribbed outer diameter | made in Xingtai, Hebei, China | working range -30 C to +100 C (short peaks to +120 C)

Because the band between shaft and housing is only 9 mm, the metal insert and the ribbed outer diameter are doing most of the work in keeping the part located and square. Once seated, the spring-loaded lip takes care of the sealing.

Key Features & Benefits

• Bonded metal insert: The insert is bonded into a narrow body so the outer diameter resists ovality when the seal is pressed into a machined housing.
• Narrow radial band: Only 9 mm separates shaft and bore, so both surfaces need to be clean and true. The ribbed outer diameter makes the best of that limited contact area.
• Seals oil and grease: The NBR lip works in circulating oil as well as in packed grease positions, so one size covers several of the stations on a unit.
• Dust lip protection: The second lip faces the outside and stops grit reaching the main lip, which is a common cause of premature leakage.
• Spring holds the lip: Garter spring loading keeps the sealing edge against the shaft as it wears, so the seal lasts beyond the first service interval.
• Confirmed by dimension: 44 mm shaft, 62 mm bore and 9 mm width is enough to pick the size from stock without a drawing.

Nominal values: 44 mm inner diameter, 62 mm outer diameter and 9 mm width. With a narrow radial band, a scored or oval bore shows up quickly, so inspect the housing before fitting.

Material & Construction

The lip compound is NBR (nitrile butadiene rubber), which resists mineral oil, grease and common gear oils and stays flexible between -30 C and +100 C (short peaks to +120 C). A metal insert bonded into the body keeps the outer diameter stable over a short press fit, and a garter spring keeps the lip loaded on the shaft. Where the position runs above the NBR range or uses a synthetic lubricant, the same 44 x 62 x 9 size can be produced in FKM, rated to about +200 C continuous.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: insert bonding strength, lip edge trim, garter spring seating and outer rib spacing checked at set intervals.
• Final: dimensional check on 44 mm inner diameter, 62 mm outer diameter and 9 mm width, hardness, lip edge, rib form 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.

The measurements taken on the run are kept with the batch record, so a carton in the field can be traced back to its production data. Inspection by a third party before shipment can be arranged when it is asked for at the enquiry stage.

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: 44 x 62 x 9 mm, or the shaft, bore and width from your assembly.
2. Quantity and destination: quantity needed, destination country and port.
3. Material: NBR, or FKM and HNBR for higher temperature or special fluids.
4. Marking and packaging: marking requirement, carton labels and barcode data.
5. Drawing or sample: useful on a narrow band where the bore may be worn.
6. Working conditions: oil or grease, temperature, speed and any vibration.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Measure the shaft at 44 mm and the bore at 62 mm, check that 9 mm of depth is available, then look at which direction the lip faced on the seal removed. The narrow band makes both diameters critical.

What are the exact dimensions of this oil seal?
44 mm inner diameter, 62 mm outer diameter and 9 mm width. Confirm the housing bore as well, since a worn bore gives the outer band less to grip.

What is the minimum order quantity?
MOQ depends on whether the 44x62x9 size is a stock item or a production order. State the quantity you need and it is confirmed with 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 after order confirmation. Both sea and air shipments are arranged, with transit time quoted to your port.

Can you supply FKM or HNBR instead of NBR?
Yes. FKM or HNBR can be supplied in this 44 x 62 x 9 size where the working temperature or the fluid is outside NBR limits. Confirm the duty when you enquire.

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

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

What information do you need to quote?
Size 44 x 62 x 9 mm, quantity, destination port, material, working temperature, fluid type, packaging requirement and the Incoterm you prefer.
