1.1 This practice prescribes the design of journal-bearing type rollers to support each end of fiber-reinforced concrete beams tested using Test Method C1399/C1399M or Test Method C1609/C1609M. The roller design is intended to provide a consistent and relatively low value of...
4.1 This practice is intended for the application of in-line, full-flow inductive wear debris sensors. According to (1), passing the entire lubrication oil flow for aircraft and aero-derivative gas turbines through a debris-monitoring device is a preferred approach to ensure sufficient detection...
5.1 This test is a simple, effective way of determining the ability of bearings to roll freely. Most bearing manufacturers do not supply information on the breakaway friction coefficient of their products and if this is a design factor, users often buy candidate bearings and try them until...
The application of cylindrical roller bearings (CRB) is widely spread in mechanical engineering. CRB can carry comparatively high loads and are usable in high speed ranges. These bearings have been proven to be variously applicable and economic. With lipped inner and outer rings CRB permit...

This specification covers ferrous needle rollers having spherical ends. Spherical-ended needle rollers designed to this specification are intended for use as bearing components. A complement of rollers is run on a hardened (HRC 58-65, see Test Methods E18) shaft and in a...
This specification covers needle roller bearing assemblies. These assemblies have thick outer rings, cages, rollers, and inner rings. The assemblies consist of a MS51961 thick outer race needle roller bearing as specified in Specification F2246 and a corresponding...
This part of ISO 5753 specifies values of radial internal clearance for the following types of radial rolling bearings: - radial contact groove ball bearings, except those for insert bearings, - double-row self-aligning ball bearings, - cylindrical roller bearings, - needle...
ESDU 81037 is the second of a group of three dealing with design considerations in rolling bearing selection. It will assist designers in those applications where a bearing arrangement consisting of a single row radial ball bearing or a single row cylindrical roller...
INTRODUCTION ESDUpac A9611 provides a computer program for calculating the key dimensions, motion characteristics, forces, torques and power requirement for the operation of either external or internal Geneva mechanisms. Both constant and varying crank angular velocity definitions are permissible....
This specification covers the procurement requirements for solid ferrous needle bearing rollers including the MS19065 spherical ended solid ferrous needle rollers as specified in Specification F2443. Intended Use-The rollers covered in this specification are intended for...
This specification covers requirements for metric series, tapered roller bearings with a single row of rollers. Intended Use-The bearings covered in this specification are intended to be used in general industrial and vehicle applications where the operating temperature does not...
INTRODUCTION This Data Item describes the use of ESDUpac A0015 which provides a computer program for analysing a disc cam/follower system. The program allows the following tribological aspects to be examined. • The surface and sub-surface stresses at the contact between the cam and follower....
