35x58x8 mm Rotary Shaft Oil Seal NBR, TC Type Shaft Seal with Metal Insert

Product Overview

A 35 mm shaft in a 58 mm bore with an 8 mm section: a middle size that appears on gearboxes, water pumps, wheel end assemblies and general industrial drives. The ribbed outer diameter presses into the housing and the spring-loaded lip runs on the shaft.

At a glance:

35x58x8 mm | NBR (nitrile butadiene rubber) | double lip TC body with 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 this size is used in both oil and grease positions, the same seal has to cope with different fluids. The NBR compound covers oil, gear oil and grease, and the dust lip on the exposed side is what keeps water and road dirt from reaching the sealing edge.

Key Features & Benefits

• Bonded metal insert: The insert is bonded into the rubber body so the outer diameter resists distortion during press fitting into a machined housing.
• Works on oil and grease: NBR tolerates both oil circulation and grease packing, so one part number covers the positions where fluids are mixed in the same workshop.
• Dust lip on the exposed side: The second lip takes the dirt first, keeping the running surface clean and reducing the chance of a lip scuff after a rebuild.
• Pressed in square: The ribbed band compresses evenly, which helps the seal sit square in the bore and avoids a leak path down one side.
• Stable lip contact: The garter spring holds pressure on the lip as the shaft surface wears, so the seal keeps working well past the first oil change.
• Dimension based selection: 35 mm shaft, 58 mm bore and 8 mm width identifies the size without reference to any catalogue number.

The part is specified as 35 mm inner diameter by 58 mm outer diameter by 8 mm width, all nominal. Confirm the bore and the shaft shoulder position on the assembly before ordering.

Material & Construction

NBR (nitrile butadiene rubber) forms the sealing element, bonded to a metal insert that stabilises the outer diameter and carries the lip load. The compound handles mineral oil, gear oil and grease across -30 C to +100 C (short peaks to +120 C), and the garter spring keeps the lip pressed to the shaft through the first years of service. Where a position runs continuously above that range, or the fluid is a synthetic lubricant, the same 35 x 58 x 8 dimensions can be produced in FKM with continuous duty to about +200 C.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: bonding between insert and rubber, lip contact width, garter spring seating and rib pattern on the outer diameter checked at set intervals.
• Final: dimensional check on 35 mm inner diameter, 58 mm outer diameter and 8 mm width, hardness, lip edge, rib pattern 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.

Each production run keeps its measured values, so the delivered carton can be traced to the run that produced it. Buyers who want an inspection before shipping can name a third party 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: 35 x 58 x 8 mm, or the measurements taken from the removed seal.
2. Quantity and destination: quantity required, destination country and port.
3. Material: NBR standard, or FKM or HNBR where the duty is hotter or the fluid synthetic.
4. Marking and packaging: size marking, label content and any barcode requirement.
5. Drawing or sample: recommended where the housing bore shows wear.
6. Working conditions: oil or grease, temperature and shaft speed, if available.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Measure the shaft, the housing bore and the width available: 35 mm, 58 mm and 8 mm on this part. Then compare the lip arrangement with the removed seal, because the dust lip position tells you which way the seal faces.

What are the exact dimensions of this oil seal?
35 mm inner diameter, 58 mm outer diameter and 8 mm width. Check the shoulder position on the shaft, since a lip can be rolled over if the seal is pushed past it.

What is the minimum order quantity?
MOQ varies with whether the 35x58x8 size is a stock line or a production order. Give the quantity you expect to use and it is confirmed together with the price.

What is the lead time, and can you ship by sea or air?
Standard sizes usually dispatch within 7 to 15 working days from order confirmation. Both sea and air carriage are available, with the cost and transit time quoted for your destination.

Can you supply FKM or HNBR instead of NBR?
Yes. If the position runs hot or the oil is synthetic, this size can be quoted in FKM or HNBR instead of NBR. State the fluid and temperature and the compound is confirmed.

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

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

What information do you need to quote?
Size 35 x 58 x 8 mm, quantity, destination port, material, operating temperature, fluid, packaging requirement and the Incoterm you prefer.
