RNA Type Heavy Duty Needle Roller Bearings with 74.8-800 kN Dynamic Load Capacity and 2640 RPM Speed Rating

NA69 RNA69 type heavy duty needle roller bearings feature a through-hardened outer ring that delivers exceptional static and dynamic load capacities, withstanding overloading, shocks, and vibration. These bearings are ideal for oscillating motion applications and can operate at high speeds when proper alignment is maintained.

• Through-hardened outer ring for maximum durability
• High static and dynamic load capacity
• Excellent resistance to overloading, shocks, and vibration
• Optimized for oscillating motion applications
• Suitable for high-speed operation with proper alignment
• Retained needles in outer ring for easy installation
• Convex inner ring raceway option (suffix R6) for improved misalignment tolerance

Shaft journals used as inner ring raceways require adequate hardness (58-64 HRC) and surface finish to achieve full load capacity. Convex inner ring raceways can accommodate misalignment up to 1 in 1000 without affecting bearing performance.

Our facility maintains IATF16949 certification since 2011, with annual production capacity exceeding 100 million bearings across various sizes and types.
