About Oil Seals
What Are Oil Seals?
Oil seals, also known as radial shaft seals, are used to retain lubricants and prevent contaminants such as dust, dirt, and moisture from entering equipment. They are commonly installed on rotating shafts in engines, gearboxes, pumps, motors, hydraulic systems, and industrial machinery.
A suitable oil seal helps reduce leakage, protect internal components, and extend equipment service life.
Materials & Performance
We supply oil seals in different rubber materials to meet various working conditions:
NBR (Nitrile Rubber) – suitable for general oil resistance, hydraulic oil, grease, and cost-effective applications.
FKM (Viton®) – suitable for high temperature, oil, fuel, and chemical-resistant applications.
ACM – commonly used in automotive and transmission systems with good heat and oil resistance.
HNBR – suitable for higher temperature, wear resistance, and demanding automotive or industrial applications.
Silicone – suitable for flexible sealing performance under low and high temperature conditions.
Material selection can be customized based on temperature, pressure, speed, shaft size, and working media.
Common Types of Oil Seals
We provide a wide range of oil seal types for different sealing structures and installation requirements:
TC Oil Seals – double-lip oil seals with spring, widely used for rotating shaft sealing and dust protection.
SC Oil Seals – single-lip oil seals with spring, suitable for oil retention in compact sealing positions.
SB Oil Seals – rubber-covered oil seals without spring, suitable for dust protection and light-duty sealing.
TB Oil Seals – metal-cased double-lip oil seals for stable installation and durable sealing performance.
Cassette Oil Seals – integrated sealing designs for heavy-duty equipment and demanding working environments.
Custom Oil Seals – non-standard sizes, special materials, and customized sealing structures based on drawings or samples.

Frequently Asked Questions
What are oil seals used for?
Oil seals are designed to retain lubricants and prevent contaminants such as dust, dirt, and moisture from entering mechanical systems. They are critical components in rotating shafts, gearboxes, and hydraulic equipment to ensure long-term performance and reduced wear.
What materials are commonly used for oil seals?
We supply oil seals in NBR (for general oil resistance), FKM/Viton® (for high temperature and chemical resistance), EPDM (for water and weather applications), and silicone (for extreme temperature flexibility). Material selection can be customized based on your working conditions.
How do I choose the right oil seal?
Selection depends on shaft size, working temperature, pressure, rotation speed, and medium (oil, grease, water, etc.). If you are unsure, our team can recommend suitable types based on your application details.
Can you provide custom oil seals?
Yes, we support custom production based on drawings or samples. We can adjust dimensions, materials, and structural design to meet specific requirements.
What information is needed for a quotation?
Please provide inner diameter (ID), outer diameter (OD), thickness, material, quantity, and application details for accurate pricing.
What is your typical lead time and MOQ?
MOQ is flexible depending on product type. Lead time varies based on quantity and specifications, with faster delivery for standard sizes.
