Rotary Shaft Seal 200x240x15 NBR A/SC Single Lip Oil Seal

Product Overview

The Rotary Shaft Seal 200x240x15 NBR A/SC is a premium radial shaft seal engineered for large rotating shafts operating in demanding industrial environments. Manufactured from high-quality NBR (Nitrile Butadiene Rubber), it provides excellent resistance to lubricating oils, greases and mechanical wear. The A/SC profile features a spring-loaded primary sealing lip that ensures reliable lubricant retention while maintaining low friction and extended service life. It is specifically designed for enclosed lubrication systems where efficient sealing and durability are essential.

Application in Industrial Systems

The Rotary Shaft Seal 200x240x15 NBR A/SC is suitable for:

• Heavy-duty industrial gearboxes
• Large gear reducers
• Hydraulic pumps
• Industrial pumps
• Conveyor drive systems
• Mining equipment

The single lip A/SC design is ideal for heavy rotating equipment operating in clean, oil-lubricated environments.

Construction and Design

The A/SC profile incorporates a rubber-covered outer diameter and a primary sealing lip with an integrated garter spring. The spring maintains constant radial pressure on the shaft, ensuring reliable lubricant retention while reducing friction and shaft wear. The optimized sealing geometry provides excellent durability, secure housing installation and long-term operational reliability.

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