[JMC] Yoke Type Track Roller NA-4903 (NA 49/17mm/30mm/13mm/37g, 1pc)

Capable of withstanding high loads due to high friction coefficient
Equipped with a cage that divides the needle rollers to prevent friction between them during high-speed rotation, allowing for high-speed rotation depending on the load
Even under high loads, if the contact surface area is wide, the contact surface stress is lower than that of ball bearings, resulting in less localized plastic deformation beyond the material's elastic limit
Suitable for light, medium, and heavy loads
Needle roller bearings are suitable for various applications as they occupy minimal space at the installation site
The outer ring assembly, RNA49, can be directly fitted onto the shaft for intermittent motion
Suitable for intermittent motion
Application
Used in automotive transmissions, universal joints, printing machines, gearboxes, small engine crankshafts, piston pins, air pumps, electromagnetic clutches, hydraulic machinery, etc.
