37x62x7 mm Rotary Shaft Oil Seal NBR, Black TC Type Shaft Seal

Product Overview

This 37 x 62 x 7 mm seal fits a 37 mm shaft into a 62 mm housing at a shallow 7 mm depth. The low profile is useful where the bore is short or where a casting rib sits close to the shaft opening.

At a glance:

37x62x7 mm | NBR (nitrile butadiene rubber) | double lip metal-cased TC with garter spring and ribbed outer diameter | made in Xingtai, Hebei, China | working range -30 C to +100 C (short peaks to +120 C)

A thin section has less rubber to hold the lip, so bore quality matters more than it does on a deep seal. The metal case and the ribbed outer diameter together keep the body aligned, and the spring-loaded lip maintains contact on a shaft that is not perfectly round.

Key Features & Benefits

• Thin 7 mm profile: Suits shallow housing recesses and short bores where a wider seal would foul the casting or stand proud of the face.
• Case holds the shape: The metal case keeps a thin section from distorting as it is pressed in, which is what keeps the lip concentric with the shaft.
• Ribbed outer band: The moulded ribs bite into the bore so the seal resists turning, an important point on shafts that start and stop under load.
• Spring-loaded lip: Continuous spring pressure compensates for lip wear and small shaft runout, keeping the sealing line closed over a long service interval.
• Moulded TC marking: The type and size are moulded into the face, so a removed seal can be identified and reordered from the part in hand.
• Fitted by dimension: Shaft 37 mm, bore 62 mm and width 7 mm is enough to confirm the size against stock.

Nominal inner diameter x outer diameter x width: 37 mm x 62 mm x 7 mm. A thin section is less forgiving of a damaged bore, so check the bore for scores before fitting.

Material & Construction

The lip is NBR (nitrile butadiene rubber), a compound that stays soft in mineral oil, grease and gear oil and keeps its sealing properties across -30 C to +100 C (short peaks to +120 C). The body is built on a metal case with a ribbed rubber outside, and a garter spring maintains lip pressure as the shaft surface polishes. For positions where the oil is synthetic or the temperature stays higher, the same 37 x 62 x 7 size 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 roundness, lip trim, garter spring seating and rib form on the outer diameter checked at set intervals.
• Final: dimensional check on 37 mm inner diameter, 62 mm outer diameter and 7 mm width, hardness, lip edge and moulded 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 measured values for the batch are filed with the shipment record so a query on delivered goods can be answered from the production data. Third-party inspection before dispatch is possible when requested in the enquiry.

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: 37 x 62 x 7 mm, or the measurements from the seal you are replacing.
2. Quantity and destination: quantity, destination country and port.
3. Material: NBR, or FKM or HNBR for a hotter or synthetic duty.
4. Marking and packaging: marking, carton label and barcode requirements.
5. Drawing or sample: recommended for a thin section fitting a shallow recess.
6. Working conditions: temperature, fluid and shaft speed, if known.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Confirm the shaft is 37 mm, the bore is 62 mm and the recess takes a 7 mm section, then match the lip direction to the removed seal. On a thin seal the recess depth matters as much as the diameter.

What are the exact dimensions of this oil seal?
37 mm inner diameter, 62 mm outer diameter and 7 mm width. Always check the recess depth, because a shallow bore will not accept the full section.

What is the minimum order quantity?
It depends on whether this size is held in stock or made for your order. State the required quantity and the MOQ is confirmed together with the unit price.

What is the lead time, and can you ship by sea or air?
Stocked sizes are usually dispatched within 7 to 15 working days after the order is confirmed. Sea and air carriage are both arranged, with costs quoted for your port.

Can you supply FKM or HNBR instead of NBR?
Yes. FKM or HNBR can be supplied in the same 37 x 62 x 7 geometry where the running temperature or fluid calls for it. Confirm the oil type at the enquiry stage.

Do you provide samples, and are they free?
Samples can be arranged for fitment checks. Sample and freight charges are quoted per request, and on a confirmed bulk order the 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 37 x 62 x 7 mm, quantity, destination port, material, temperature, fluid, packaging requirement and preferred Incoterm.
