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.

Cylindrical Rollers

Cylindrical Rollers

Cylindrical rollers are used in bearings where the majority load is in the radial direction. Although mostly cylindrical in shape, some specialist bearings have convex barrel shapes or concave profiles depending on the application type and conditions. Pure cylindrical roller bearings cannot support any load in an axial direction. If axial support is required a separate bearing arrangement will be required.
