CORTECO 01003157 NBR B2 40x72x12 mm Shaft Seal

Applications

The CORTECO 01003157 shaft seal in size 40x72x12 mm is engineered for industrial and heavy-duty rotary shaft sealing applications. Constructed with nitrile-butadiene rubber (NBR) and built to type B2 specification, this seal ring is ideal for bearing housings, bearing units and agricultural equipment drives (notably referenced for CLAAS 02357300). Its standard dimensions (inner diameter 40 mm, outer diameter 72 mm, width 12 mm) allow integration into existing systems requiring oil-resistant sealing of rotary shafts under moderate speed and load.

Advantages

• High durability material (NBR): The nitrile-butadiene elastomer provides excellent resistance to oils, greases and industrial lubricants, significantly improving maintenance intervals and operational life.

• Type B2 construction: Designed for rotary shafts, the B2 geometry provides a robust sealing lip and controlled radial and axial performance, limiting leakage and contamination ingress in industrial and mobile equipment.

• Standard size for easy servicing: With 40x72x12 mm dimensions, this seal enables straightforward replacement in bearing units or sealing housings without redesign—a key advantage for procurement and maintenance teams.

• Heavy-duty readiness: The product meets OEM specifications for agricultural and industrial OEM systems, making it suitable for farm machinery, industrial drives and other demanding setups.

• Clear technical specification: As a procurement-ready component, the seal supports specification clarity, cataloguing and supply chain integration for B2B customers.

FAQ

Q1: What does the “B2” designation denote?
A1: B2 indicates a standard construction type for rotary shaft seals with a specific lip geometry and sealing performance for rotating shafts in industrial and mobile equipment.

Q2: Is the NBR material suitable for exposure to oils and industrial lubricants?
A2: Yes. NBR (nitrile-butadiene rubber) is widely used in rotary seals for its strong resistance to mineral oils, greases and many industrial fluids, making it appropriate for heavy-duty sealing tasks.

Q3: Can this seal be installed without modifying an existing bearing unit?
A3: Yes. The 40x72x12 mm size is a standard dimension facilitating direct replacement in many bearing housing assemblies without structural changes, aiding fast maintenance turnaround.

Q4: In what environments is this seal particularly useful?
A4: This seal is suited for agricultural machinery, gearboxes, bearing units in industrial drives, mobile equipment and any system where rotary shaft sealing in demanding conditions is required.
