DESC:TECHNICAL FIELD
[001] The embodiments herein generally relate to bearings and more particularly, to a roller bearing assembly (needle roller bearing assembly, cylindrical roller bearing assembly and the like) for use in applications such as vehicles, machines and the like, which comprises a modular spring-loaded bearing cage and roller assembly, and a rotating member having various sizes (outer diameter dimensions), where the modular spring-loaded bearing cage and roller assembly is configured to be automatically adjusted to at least one of a plurality of sizes (inner diameter dimensions) in accordance to corresponding sizes (outer diameter dimensions) of the rotating member therein to facilitate mounting of the modular spring-loaded bearing cage and roller assembly onto the rotating member having various sizes, wherein the rotating member is at least one of a bush and an inner bearing ring. The modular spring-loaded bearing cage and roller assembly can also be mounted onto other rotating members such as shafts, axles and the like having various sizes (outer diameter dimensions).

BACKGROUND
[002] Generally, bearing is a means which allows rotating members such as shafts, axles and the like, to rotate or move in contact with another rotating part with less friction. Bearings are used to support the rotating member (shaft, axle and the like) and facilitate smooth rotational motion of the rotating members by reducing the friction between rotating members. Bearings are commonly used in a power transmission unit (gearbox assembly) of vehicles, industrial machines, and the like. Bearings are also used in engines, electric motors, pumps, motorcycles, wind turbines and paper making industrial machines.
[003] Many plain bearings (bushes) have been used for automotive transmissions. However, in order to prevent seizure caused in the bushes or to reduce torque required for the automatic transmissions, the plain bearings have been substituted by needle roller bearing. The needle roller bearing (hereinafter NRB) and bush (plain and flanged) are manufactured separately by different manufacturers. The bush is generally press fitted on shaft. Hence, any variation in bush inner diameter (ID) and outer diameter (OD) will have direct impact on performance and life of NRB. The NRB may break if the flange bush is assembled upside down (or) reverse way. Further, unmatched assembling of the NRB may produce scratch mark on gear bore, NRB rollers and on the bush OD. Thus, leading to reduced NRB life and performance. The assembling (mounting) of single NRB onto rotating member such as bushes having various sizes is difficult and is one of the challenges posed to original equipment manufacturers (OEM’S).
[004] Therefore, there exists a need for a roller bearing assembly, and a bearing cage and roller assembly, which obviates the aforementioned drawbacks. Further, there exists a need for a modular spring-loaded bearing cage and roller assembly, which automatically adjusts the size of the modular spring-loaded bearing cage and roller assembly in accordance to various sizes of a rotating member such as bush, inner bearing ring, shaft, axle and the like.
