Rotary Shaft Seal 205x230x16 NBR A/SC Single Lip Oil Seal

Product Overview

The Rotary Shaft Seal 205x230x16 NBR A/SC is a premium radial shaft seal engineered for sealing large rotating shafts operating in demanding industrial environments. Manufactured from high-quality NBR (Nitrile Butadiene Rubber), it offers excellent resistance to lubricating oils, greases and mechanical wear. The A/SC profile features a spring-loaded primary sealing lip that provides reliable lubricant retention while maintaining low friction and long service life. It is an ideal sealing solution for enclosed lubrication systems used in heavy industrial machinery.

Application in Industrial Systems

The Rotary Shaft Seal 205x230x16 NBR A/SC is suitable for:

• Heavy-duty industrial gearboxes
• Large gear reducers
• Hydraulic pumps
• Industrial pumps
• Mining equipment
• Steel processing machinery
• Paper manufacturing equipment
• Cement production machinery
• Conveyor drive systems
• Marine equipment
• Heavy industrial machinery
• OEM applications

The A/SC single lip profile is designed for oil-lubricated systems where efficient sealing and low operating friction are essential.

Construction and Design

The A/SC profile incorporates a rubber-covered outer diameter and a primary sealing lip with an integrated garter spring. The garter spring maintains constant radial pressure against the shaft, ensuring reliable lubricant retention while minimizing friction and shaft wear. The optimized sealing geometry provides long service life, secure housing installation and dependable operation under continuous industrial use.

Material Properties

The seal is manufactured from premium NBR (Nitrile Butadiene Rubber).

NBR provides excellent resistance to:

• Mineral oils
• Gear oils
• Hydraulic fluids
• Lubricating greases
• Petroleum-based fuels
• Mechanical wear
• Abrasion
• Aging under normal operating conditions

Its excellent balance of flexibility, durability and cost efficiency makes NBR one of the world's most widely used elastomers for rotary shaft sealing applications.
