1.NBR 70 O-Ring Performance Specifications
Nitrile rubber(NBR)is the most widely used elastomer for o-rings and seals due to its excellent resistance to petroleum-based oils,fuels,and greases.Nitrile(Buna-N)provides good mechanical properties,high abrasion resistance,and reliable performance at a low cost.Standard NBR 70 durometer compounds operate effectively in temperatures from -40℃ to +120℃(-40F to 250°F).These seals offer excellent tensile strength,tear resistance,and low compression set,making them ideal for dynamic applications involving constant movement.The as-326 o ring,with its thicker cross-section,delivers robust sealing against contaminants,pressure leaks,and mechanical wear in heavy-duty industrial environments.
2.Conveyor,Elevator,and Stacker Working Conditions
Logistics and warehousing equipment such as conveyors,elevators,and stacker machines forms the backbone of material handling and supply chain operations.These systems rely heavily on hydraulic cylinders,drive motors,and high-pressure lines that experience repetitive stress,vibration,and dusty conditions.In hydraulic lift systems,bucket elevators, and stacker cranes,NBR o-rings seal cylinders and connectors to prevent oil seepage under heavy loads.Buna-N nitrile seals are widely used in hydraulic applications for forklifts,conveyor drives,and lifting equipment due to their superior oil resistance and durability against abrasion from grit and friction.The AS-326 size is commonly applied in large hydraulic line connectors and motor housings to maintain pressure and lifting capacity without leaks.

Conclusion
To ensure the long-term reliability of material handling systems like conveyors,elevators, and stackers,the as-326 o ring provides heavy-duty sealing for hydraulic drive units and high-pressure connections.Maintaining a comprehensive nbr o ring kit allows technicians to quickly replace worn seals and minimize downtime in warehouses and distribution centers.Always confirm the NBR 70 Shore A specifications match your equipment's hydraulic fluid and pressure requirements for optimal performance.
