FAQ

Q1: Why use NBR 70 ShA for industrial O-Rings?
A1: NBR (nitrile rubber) at a hardness of 70 ShA provides an excellent combination of elasticity and mechanical strength. It is highly effective for sealing in systems exposed to oils, lubricants and standard industrial fluids.

Q2: What kinds of equipment use an O-Ring 91.44x5.33 mm?
A2: This size is commonly applied in medium to large hydraulic or pneumatic systems, machine assemblies, pump housing covers and valve applications where an internal diameter around 91.44 mm and a cross-section of approximately 5.33 mm are required.

Q3: Is this O-Ring suitable for oil-rich environments?
A3: Yes, the NBR 70 ShA compound offers strong resistance to mineral oils, greases and many standard industrial fluids, making it ideal for hydraulic, pneumatic and machine-maintenance applications.

Q4: How to verify correct O-Ring sizing?
A4: Confirm the inner diameter (ID = 91.44 mm), cross-section (CS = 5.33 mm) and ensure the material and hardness (NBR 70 ShA) fit the service conditions (fluid type, temperature, motion). When all align, this O-Ring is appropriate.

Q5: Is this product practical for B2B procurement and inventory?
A5: Absolutely. Because of its standard size and widely accepted material specification, it is well-suited for industrial spare-parts stocking, maintenance stores and procurement planning aimed at minimizing downtime.
