Description: 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. It can be used in applications where the bearing envelope dimensions need to be kept to a minimum. It tends to have slightly rounded ends as a stress-relieving feature, improving performance and life characteristics. Piston Pin or gudgeon pin or wrist pin is an integral part of all types of internal combustion engines. It is a component used to fasten the piston and the connecting rod severally and securely, but at the same time permitting enough play for the free angular movement of the connecting rod according to the requirements of kinematics of the engine assembly. Crank Pin is a vital part of kinematics of the transmission of a two/three wheeler assembly, where a direct transfer of power, without slip, is sought from the piston to the wheel/gear box. It is firmly connected to the connecting rod and as such the geometry of the outer diameter as well as side faces plays a vital role in fitment and running. It is a high precision item, having round cylindrical shape. It can be of hole or solid type with specially designed lubrication holes, with a high surface finish, to serve as running surface for needle bearings.
