O-Ring 150x10 mm NBR

Applications

The O-Ring 150x10 mm NBR 70 Shore is designed for industrial-scale sealing tasks requiring a large inner diameter rubber gasket. With an inner diameter (ID) of 150 mm and a cross-section thickness of 10 mm, this sealing ring is ideal for heavy equipment such as hydraulic cylinders, pump casings, large bearing units and static seal interfaces within manufacturing, plant maintenance and mobile machinery sectors. The nitrile-butadiene rubber (NBR) compound with 70 Shore A hardness ensures robust performance in industrial sealing, hydraulic and pneumatic applications, rubber gasket systems and technical sealing components.

Advantages

• Large diameter format - The 150 mm ID and 10 mm cross-section allow a single O-Ring to cover larger bores, reducing the number of individual seals and streamlining part management.

• Material strength and chemical resistance - NBR provides excellent resistance to mineral oils, greases, hydraulic fluids and many aliphatic hydrocarbons.

• Ideal hardness for demanding use - At 70 Shore A the material enables a good balance between flexibility and structural integrity, allowing reliable static sealing and moderate dynamic use.

• Procurement-friendly B2B format - A standardised large size supports inventory consolidation, simplifies billing and reduces downtime for maintenance operations.

FAQ

Q1: What does “150x10 mm” mean?
A1: It refers to an O-Ring with an inner diameter of 150 mm and a cross-section (thickness) of 10 mm — suitable for sealing large-bore components.
Q2: Why is NBR material with 70 Shore hardness chosen for this O-Ring?
A2: NBR with 70 Shore A offers a balanced performance between elasticity and strength, providing excellent resistance to oils, greases and moderate hydrocarbon exposure—ideal for industrial sealing applications.
Q3: Can this O-Ring be used in hydraulic or pneumatic systems?
A3: Yes — this size and material specification suit hydraulic cylinders, pump housings, large bearing units and other systems requiring reliable large-diameter seals.
Q4: What are the procurement benefits of the large-ID format?
A4: Using a single large-ID O-Ring reduces the number of smaller parts, simplifies inventory control, supports quicker installation and enables faster service turnaround.
Q5: Are there limitations regarding temperature or media compatibility?
A5: While the seal performs well between -30 °C and +100 °C (short-term +120 °C) and resists many oils, it may not be ideal for long-term exposure to UV/ozone, aromatic fuels or certain aggressive solvents.
