“…Initially in the present work author has carried out sufficient literature review (Somasundar & Krishnamurthy, 1984;Harris & Aaronson, 1967;Bamberger, Parker & Dietrich, 1976;Bhateja & Hahn, 1980;Murthy & Rao, 1983;Hong & Jianjun, 1998;Zhao, 1998;Yangang, Raj & Qingyu, 2004;Darji & Vakharia, 2008) and market survey to understand the practical application of hollow cylindrical roller bearing and its advantages in comparison with solid roller bearing. It is concluded that bearing manufacturer are production these type of bearing as per the requirement, but no standard formula or catalogue is available through which user can directly select hollow cylindrical roller bearing.…”

“…To reduce this kind of failure, a hollow roller was suggested in the bearing (Bamberger et al , 1976). Hollow rolling elements have advantages of higher speeds, as these are required in various applications (Harris and Aaronson, 1967; Bowen and Bhateja, 1980; Bhateja and Hahn, 1980; Murthy and Rao, 1983; Zhao, 1998). Hollow rollers possess better lubrication, lighter weight and high rotational speeds than the solid rollers.…”

Purpose The purpose of this paper is to develop a mathematical model to determine optimum hollowness of a layered cylindrical hollow rolling element when it contacts with a flat plate. Design/methodology/approach In this work, finite element analysis (FEA) is carried out for different hollowness percentages ranging from 10 to 90 layered cylindrical hollow rolling elements corresponding to five standard NU 22 series bearings, i.e. 2206, 2210, 2215, 2220 and 2224. An experimental investigation is carried out for the NU 2206-layered cylindrical hollow roller bearing (LCHRB) at optimum hollowness under static loading condition. Findings Different parameters, such as bending stress (von Mises stress at the bore of the roller), von Mises stress, contact pressure and deflection in loaded contact are presented here. Originality/value The value of this research work is the development of a generalized solution that can be used to find the exact value of optimum hollowness for the layered cylindrical hollow rolling element, which is dependent on the yield strength of the material and the geometry of the roller under static loading condition. A static load test rig is designed to observe the load carrying capacity of the LCHRB as compared to the hollow cylindrical roller bearing.

“…Hollow cylindrical roller bearings are advantageous for higher speeds and loads, as they are required in various applications (Harris and Aaronson, 1967;Bowen and Bhateja, 1980;Bhateja and Hahn, 1980;Murthy and Rao, 1983;Zhao, 1998). Cylindrical roller bearings having hollow rollers possess lower weight, better lubrication capabilities and higher operating speeds as compared to solid rollers.…”

Purpose The purpose of this paper is to extend the Hertz equation for the contact interaction between a layered cylindrical hollow roller and a flat plate through an experimental technique. Design/methodology/approach In this work, an experimental investigation is carried out for an elastic contact between layered cylindrical hollow rollers of different hollowness, ranging from 30 to 75 per cent hollowness and a flat plate. The footprint method was used for the evaluation of the contact width corresponding to the applied load. Findings The contact width for the layered cylindrical hollow roller was evaluated and the Hertz equation was extended on the basis of the experimental results. Originality/value The value of this research work is the development of an extended Hertz equation for a cylinder-on-plate configuration for a new kind of cylindrical roller.
