Rotary Shaft Seal 55x85x10 NBR TC - Double Lip Oil Seal

Applications of the 55x85x10 NBR TC Rotary Shaft Seal

The 55x85x10 NBR TC double lip oil seal is designed for demanding industrial, automotive, hydraulic, and mechanical power transmission applications. Its TC construction (outer rubber coating + spring-loaded primary lip + dust lip) ensures stable sealing performance in environments exposed to oil, grease, dirt, and dynamic shaft motion. Common uses include electric motors, gearboxes, pumps, combustion engines, machine tools and industrial drives where reliable rotary oil sealing is required.

Key Advantages and Performance

Manufactured from high-quality NBR (Nitrile Butadiene Rubber), this rotary shaft seal offers excellent resistance to oils, lubricants, fuels, and grease, maintaining sealing stability even during extended operation. The double lip design provides enhanced protection compared to single lip seals (SC), supporting both lubricant retention and external contamination control. Engineered for high durability, reduced friction, and long service intervals, the seal ensures secure shaft sealing in a wide range of technical and industrial applications.

Main Product Description

This Rotary Shaft Seal 55x85x10 NBR TC is a precision-engineered oil seal designed to deliver reliable sealing performance in dynamic motion systems. Its double lip construction ensures efficient lubrication retention while preventing the ingress of dust, moisture, and other external contaminants. Compared with a single lip oil seal, the TC design provides stronger protection and better operational stability in machines operating under continuous or moderate load.

Constructed from high-grade NBR elastomer, this seal offers proven resistance to mineral oils, hydraulic fluids, and mechanical grease, making it suitable for a wide range of industrial applications. The rubber-coated exterior ensures excellent housing fit and vibration absorption, while the internal spring applies consistent radial force to maintain proper shaft sealing even during extended operation or minor shaft misalignments.

Ideal for integration in gearboxes, motors, pumps, compressors, agricultural machinery, and automotive engines, this rotary oil seal meets the technical expectations of maintenance professionals and B2B buyers who require long-lasting, robust sealing solutions. Engineers value the balance between durability, chemical resistance, and cost-effectiveness—attributes that make this TC-type seal one of the most widely used in modern equipment.

The 55x85x10 NBR TC double lip seal ensures dependable sealing performance, minimizes leakage, and extends machine service life, contributing to reduced downtime and lower operating costs. It is a proven solution for companies seeking an efficient, trustworthy technical seal for rotating components.

FAQ

1. What is the difference between a single lip and a double lip oil seal?
A single lip (SC) seal retains lubricant, while a double lip (TC) seal adds an external dust lip for enhanced contamination protection in harsher environments.

2. Which material is best for oil and grease resistance?
For general industrial applications, NBR is optimal due to its excellent resistance to oils, fuels, and lubricants. For high temperatures or chemicals, FKM/Viton may be required.

3. How do I select the correct shaft seal size?
Match the inner diameter to the shaft, the outer diameter to the housing, and the width to the available installation space. Material and lip design should match the operating conditions.

4. Is the 55x85x10 NBR TC seal suitable for engines and pumps?
Yes. The TC double lip design provides stable sealing for motors, pumps, gearboxes, and engines exposed to oil and rotating motion.

5. Can this double lip seal handle contaminated environments?
Yes. The dust lip significantly improves resistance to dirt, moisture, and external contamination.
