75x110x13 mm FKM Rotary Shaft Oil Seal, High Temperature Brown Lip Seal

Product Overview

This 75 x 110 x 13 mm seal is produced in fluorocarbon rubber so it can keep sealing where ordinary nitrile would harden and crack. It is used on shafts running hot, or where the lubricant is synthetic or heavily additised.

At a glance:

75x110x13 mm | FKM / FPM (fluorocarbon rubber) | single lip, garter spring, metal-cased body | made in Xingtai, Hebei, China | working range -20 C to +200 C

The lip is loaded by a garter spring inside a metal case, and the brown FKM compound is bonded over the case in the usual way. Because the material is chosen for temperature rather than for price, it is normally specified where a shorter seal life has already been experienced.

Key Features & Benefits

• Stable at high temperature: FKM keeps its sealing force up to about +200 C in continuous service, so the lip does not harden and start weeping as quickly as nitrile.
• Suits synthetic lubricants: Fluorocarbon rubber resists synthetic oils, ester based fluids and aggressive additive packages better than the general purpose compound.
• Spring keeps the lip loaded: Even at temperature the garter spring maintains radial force, so sealing does not depend on rubber elasticity alone.
• Case for a firm press fit: A metal case holds the bore diameter steady, which matters on housings that see heat cycling and differential expansion.
• Wider 13 mm body: The longer case gives a bigger seating area for equipment that sees load reversal and vibration.
• Escalation made easy: Units that have already consumed nitrile seals can be moved to this size and compound without any change to the housing.

Sizes are nominal and are quoted as inner diameter x outer diameter x width. Confirm against the removed seal or a measured shaft and housing bore before ordering, and match the compound to the working temperature and fluid.

Material & Construction

The sealing element is FKM, also written FPM, a fluorocarbon rubber chosen for heat and chemical resistance rather than for general purpose service. It holds continuous duty from -20 C to +200 C and stands up to synthetic lubricants, hot air and many aggressive additive packages that would attack nitrile. The compound is bonded to a steel case and the lip is held on the shaft by a garter spring. Because low temperature flexibility is the one area where FKM gives ground, a duty that regularly runs below freezing can be quoted in NBR or HNBR in the same 75 x 110 x 13 geometry.

Quality Control and Inspection

• Incoming: compound hardness checked before release to production.
• In process: compound batch control, case concentricity, lip geometry, spring seating and bond quality checked at set intervals.
• Final: inner diameter, outer diameter and width measurement, rubber hardness, lip edge inspection 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.

Inspection before dispatch by the buyer or a nominated third party can be arranged; state the requirement in the enquiry so it is quoted with the order.

Packaging, Carton and Delivery

Standard packing is individual polybag, inner carton, then export carton. Carton marks, labels and barcodes are printed to buyer specification.

In stock: ships in 1 to 2 days. Not in stock but still in current production: 10 to 15 days. Not in stock and not in production: 25 to 30 days. 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: 75 x 110 x 13 mm, or the reading from the failed seal.
2. Quantity and destination: pieces required, destination country and port.
3. Material: FKM as standard here; NBR or HNBR can be quoted if the duty is cooler.
4. Marking and packaging: seal print and carton labelling requirements.
5. Sample or drawing: send one where the part is matched from service.
6. Working conditions: continuous temperature, peak temperature, fluid type and shaft speed.

Frequently Asked Questions

How do I confirm this seal fits my assembly?
Measure the shaft, the housing bore and the depth for the seal. Values of 75 mm, 110 mm and 13 mm give the fit, and the fluid and working temperature then decide whether FKM is the right compound.

What are the exact dimensions of this oil seal?
75 mm inner diameter, 110 mm outer diameter and 13 mm width. Verify your own sample or drawing as well, because shoulder position and housing depth differ between units.

What is the minimum order quantity?
The MOQ follows whether the size and compound are stocked or produced for you. Tell us the volume you need and the quotation confirms the MOQ with price breaks above it.

What is the lead time, and can you ship by sea or air?
In stock: ships in 1 to 2 days. Not in stock but still in current production: 10 to 15 days. Not in stock and not in production: 25 to 30 days. Sea and air freight are both arranged.

Can you supply FKM or HNBR instead of NBR?
This size is produced in FKM as standard, so high temperature duty is already covered. If your application runs cooler, or the fluid suits a different elastomer better, the same 75 x 110 x 13 geometry can be quoted in NBR or HNBR.

Do you provide samples, and are they free?
Samples for evaluation can be supplied. Sample and freight costs are quoted per request, and on a confirmed bulk order the sample charge is normally set off against the order value.

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 old seal, quantity, compound, continuous and peak temperature, fluid type, packing and marking needs, and the destination port.
