We are committed to providing quick and reliable service, ensuring your Oil seals are delivered in the shortest time possible without compromising on quality.
We work efficiently to deliver high-quality Oil seals on time. Here’s a breakdown of the whole production process:
We use high-quality NBR, FKM, and other elastomers to mold oil seals according to specifications.
Every batch undergoes rigorous leak-proof, pressure, and durability tests to ensure performance.
All seals are securely packed to prevent damage and shipped via trusted logistics partners.
For specialized applications, we modify size, material, and design as needed.
An oil seal, also known as a shaft seal or rotary seal, is a critical component used in machinery and automotive systems to prevent lubricant leakage and block contaminants like dust, dirt, and moisture. It works by forming a tight barrier around rotating shafts, ensuring smooth operation and extended equipment life.
Selecting the right oil seal depends on several factors: Operating Speed & Pressure – Choose a seal rated for your system’s RPM and pressure levels. Material Compatibility – NBR oil seals are great for general applications, while FKM oil seals resist high temperatures and chemicals. Seal Type – Use dual-lip seals for extra dust protection and high-pressure seals for hydraulic systems.
The lifespan of an oil seal varies based on operating conditions, but they generally last 3-5 years. To extend longevity: Use the right material for your application (NBR for standard use, FKM for high-temperature conditions). Ensure proper installation to avoid damage or leakage. Lubricate appropriately to prevent premature wear. Inspect regularly for signs of cracks, hardening, or leakage, and replace if necessary.
There are several types of oil seals, each designed for different applications: TC Oil Seal – Dual-lip design for enhanced sealing and dust protection. TG4 Skeleton Oil Seal – Used in high-speed rotating shafts. Split Opening Oil Seal – Easy installation without disassembling machinery. K Type Oil Seal – Ideal for high-temperature and high-pressure environments. TCV High-Pressure Oil Seal – Designed for hydraulic and industrial applications.
Oil seals are typically made from: NBR (Nitrile Rubber) – Affordable and resistant to oil and grease, suitable for general industrial use. FKM (Fluorocarbon Rubber) – Withstands high temperatures and chemicals, ideal for automotive and hydraulic systems. PTFE (Teflon Oil Seal) – Used in extreme conditions with aggressive chemicals and high speeds. Choosing the best oil seal material depends on temperature, pressure, and fluid compatibility.
For wholesale oil seals, choose a supplier that offers: High-quality NBR/FKM materials for durability. Custom sizes tailored to your requirements. Fast delivery with a 3-day production time for urgent orders. Competitive factory pricing with low MOQ.
