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...
1.1 This specification covers needle roller bearings having thick outer rings, with rollers and cages. 1.2 The bearings being specified are intended to be used with hardened shafts (HRC58-65; see Test Methods E18). For use with unhardened shafts, bearings should be used in conjunction...
This specification covers annular ball bearings intended primarily for use in instrument and precision rotating components. Annular ball bearings for instrument and precision rotating components shall be of the following types, as specified: type I - deep groove, unflanged; type II - deep groove,...
5.1 Relevance of the Spiral Orbit Tribometer (SOT)-The SOT was designed to evaluate the relative degradation rates of liquid lubricants in a contact environment similar to that in an angular contact bearing operating in the boundary lubrication regime. It functions as a...
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...
This specification covers needle roller bearing assemblies that have thick outer rings, cages, rollers and inner rings. The assemblies consist of a MS51961 thick outer race needle roller bearing as specified and a corresponding MS51962 inner ring as specified. The...
5.1 Total Facet Prosthesis Components-The total facet replacement may comprise a variety of shapes and configurations. Its forms may include, but are not limited to: ball-and-socket articulating joints, joints having a free-floating or semi-constrained third body, metallic load-bearing...
1.1 This specification covers inner rings for needle roller bearings having thick outer rings. 1.2 The inner rings being specified are intended for use on unhardened shafts in conjunction with the MS51961 needle roller bearings specified in Specification F2246. 1.2.1 For needle...
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...
5.1 This guide can be used to develop test parameters for evaluating fatigue and wear behavior of IVD prostheses under impingement loading. It must be recognized, however, that there are likely many possible impingement conditions for a given IVD prosthesis. 5.2 The user should attempt to determine...
This specification covers needle roller bearing assemblies that have thick outer rings, cages, rollers and inner rings. The assemblies consist of a MS51961 thick outer race needle roller bearing as specified and a corresponding MS51962 inner ring as specified. The...
INTRODUCTION This Data Item presents a procedure for assessing the suitability of a user-specified commercial needle-bearing roller follower driven by a disc cam. The choice of an appropriate roller follower is an important step in the design of cam systems used in many...
