Rotary Shaft Seal 160x190x13 NBR B2 Single Lip Oil Seal

Product Overview

The Rotary Shaft Seal 160x190x13 NBR B2 is a premium radial shaft seal designed for reliable sealing of large rotating shafts operating in demanding industrial environments. Manufactured from high-quality 70 Shore NBR (Nitrile Butadiene Rubber), it offers excellent resistance to lubricating oils, greases and mechanical wear. The B2 profile features a spring-loaded primary sealing lip combined with a reinforced metal case, providing excellent dimensional stability, secure housing installation and long-lasting sealing performance.

Application in Industrial Systems

The Rotary Shaft Seal 160x190x13 NBR B2 is suitable for:

• Industrial gearboxes
• Heavy-duty gear reducers
• Hydraulic pumps
• Industrial pumps
• Electric motors
• Compressors
• Conveyor drive systems
• Mining equipment
• Steel processing machinery
• Agricultural machinery
• Construction equipment
• OEM applications

The B2 profile is engineered for demanding applications where rigid installation, reliable lubricant retention and long service life are required.

Construction and Design

The B2 profile incorporates a reinforced metal outer case together with a primary sealing lip fitted with an integrated garter spring. The spring maintains constant radial pressure against the shaft, ensuring effective lubricant retention while minimizing friction and shaft wear. The metal case improves structural rigidity, installation precision and long-term dimensional stability.

Material Properties

The seal is manufactured from premium 70 Shore 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 durability, elasticity and cost efficiency make NBR one of the most widely used sealing materials for rotary shaft seals in industrial machinery.
