Key technical specifications include:

• Shaft diameter range: Typically from 10 mm to 200 mm, with custom sizes available up to 500 mm.
• Dynamic load rating (C): Ranges from 5 kN to over 300 kN depending on the series.
• Static load rating (C0): Usually 1.5 to 2 times the dynamic rating.
• Speed limits: Up to 8,000 RPM for grease-lubricated versions and higher for oil-lubricated systems.
• Temperature range: Standard models operate from -30°C to +120°C, with high-temperature variants reaching 200°C.

International standards governing these bearings include:

• ISO 104:2015 – Rolling bearings: Thrust bearings, boundary dimensions, and tolerances.
• DIN 722 – German standard for needle roller bearings, widely adopted in European machinery.
• ABMA 9:2015 – American Bearing Manufacturers Association standard for load ratings and fatigue life.
• JIS B 1513 – Japanese Industrial Standard, commonly referenced in Asian markets.

Compliance with these standards ensures interchangeability, reliability, and safety across global supply chains.
