Needle Rollers
Needle Rollers
Needle Rollers are mainly known as Rolling Element but also act as Bearing if to be used on hard shaft and housing. Needle rollers are used where radial load and medium speeds are encountered. Needle rollers can also be useful in applications where the bearing envelope dimensions need to be kept to a minimum. Needle rollers tend to have slightly rounded ends as a stress-relieving feature, improving performance and life characteristics.
