NA69/22 Machined Needle Roller Bearing
NA69/22 Machined Needle Roller Bearing are with cylindrical rollers of small diameter relative to their length. Improved roller/raceway profile prevents stress peaks for longer bearing life.
Advantage:
● Smaller rollers and reduced overall bearing length
● Increased number of rollers, higher top speed
● Increased contact area between rollers and raceways for higher load carrying capacity
● Reduced noise and vibration levels
Shortcoming:
● More expensive than bearings with rolling elements
Needle bearings are commonly used in applications requiring high precision and low friction. Some industries that use needle roller bearings NA69/22 include:
● Motor vehicles
● Robot
● Machinery
● Aerospace
● Electronic product
