Radial Shaft Seals
Seals
Radial shaft seals, often referred to as oil seals, are essential for sealing rotating machine elements. They function by closing the gap between rotating and non-rotating parts, preventing leakage of fluids while keeping contaminants out of the system.
By retaining fluids and preventing external contaminants, radial shaft seals protect vital components, enhancing the efficiency and longevity of machinery.
Our Trusted Suppliers
We partner with leading manufacturers like Parker, Freudenberg, JM Clipper, and Trelleborg to deliver the highest-quality and most reliable radial shaft seals.
Design Specifics
Radial shaft seals sit between rotating and non-rotating mechanical components, creating a complete seal, often to keep fluids on one side free from leakage or contamination. Common materials include nitrile butadiene rubber (NBR or Buna-N), fluoroelastomer (FKM), polytetrafluoroethylene (PTFE), and silicone (VMQ), which have varying temperature resistance but all stand up to pressure changes and motion while reducing friction.
Oil seals come in four main types: rubber-cased, metal-cased, premium sine seal (PSS), and cassette seals. All have unique designs and strengths, making them ideal for varying use cases.
How Oil Seals Work
Radial shaft seals feature a unique design that maintains sealing integrity under both static and dynamic conditions, which is critical for long-term reliability. This combination helps them excel in environments with high pressures, extreme temperatures, and exposure to aggressive fluids.
