Oil Seal Quote: What to Send and How to Request Pricing
Quick Answer: An oil seal quote requires the seal type, dimensions, material, and operating conditions. Send the shaft diameter, housing bore, width, temperature, fluid, pressure, shaft speed, and required quantity to CORASEALS for a quotation.
Oil seal pricing changes with size, material, lip design, quantity, and special requirements. A complete oil seal quote request reduces back and forth. A complete quote request also helps the supplier verify that the seal fits the shaft, housing bore, and installation space before pricing.
CORASEALS supplies oil seals, rotary shaft seals, radial shaft seals, lip seals, and related sealing products for industrial buyers, repair shops, distributors, and equipment builders. The guide below explains what we need for an oil seal quote.
What to Include in an Oil Seal Quote Request
Send the following details when requesting an oil seal quote from CORASEALS. A drawing or sample photo is always preferred when the type code is unclear.
- Seal type or profile: single lip, double lip, metal case, rubber covered, cassette seal, V-ring, or another profile. Include the type code if you have one, for example TC or SC. Type codes can differ between catalogs, so a cross section drawing matters.
- Dimensions: inside diameter × outside diameter × width. State the units in millimeters or inches.
- Shaft diameter and housing bore: If the seal installation is new, provide both measurements plus the width.
- Material: NBR, FKM, HNBR, EPDM, silicone, PTFE, or another compound. Material must match the fluid and temperature.
- Operating conditions: medium, temperature range, pressure, shaft speed in rpm or m/s, runout, and shaft surface finish.
- Quantity: sample quantity, prototype quantity, or annual volume. Quantity affects unit price and possible tooling.
- Drawing, photo, or reference number: A clear drawing or sample photo helps identify the lip type and case design.
Oil Seal Dimensions and Measurement
Oil seal dimensions follow the order ID × OD × width. The inside diameter matches the shaft, the outside diameter matches the housing bore, and the width matches the installation space. A small error in any of these measurements causes leakage or damage during installation.
Confirm the unit on your drawing before sending an oil seal quote request. Do not mix millimeters and inches. If the seal was removed from a machine, measure the metal case OD, the flexible lip ID, and the overall width. Take more than one measurement if the old seal is worn or deformed.
When the shaft is scored or worn, mention the shaft condition in the quote request. A repair sleeve or a different lip design may be required. Shaft runout, surface finish, and installation depth also affect seal life.
Operating Conditions That Affect an Oil Seal Quote
The same oil seal dimensions may require different materials and lip designs depending on the application. A gearbox oil seal running at high shaft speed needs a different lip arrangement than a low speed wheel hub seal. CORASEALS needs the fluid, temperature, pressure, and shaft speed to quote the correct oil seal.
EPDM is not suitable for most mineral oil environments. Nitrile NBR works in many general oil sealing applications. FKM and HNBR are used when temperature or chemical resistance is higher. The fluid matters more than temperature in some cases because a material can survive heat but swell in the wrong fluid.
Shaft speed and pressure also matter. High speed lip seals often need special lip geometry or lower interference. High pressure applications may require a retained case, a different spring design, or a backup ring.
