This part of ISO 2982 specifies: - dimensions of locknuts; - runout tolerance of locknut clamp face with respect to pitch diameter of screw thread; - dimensions of lockwashers with straight inner tab for use with 4-slot thread; - dimensions of locking clip assemblies for use with 8-slot...

Scope and field of application This standard specifies dimensions and requirements for materials, marking, use and installation of rotary shaft lip seals used for retaining fluid or grease in unpressurized equipment, or equipment with a low differential pressure, that has rotating...

This document specifies the method for comparing performance evaluation results for a foil thrust bearing that supports load with aerodynamic force generated by the rotation of a driving shaft and lubricates using air, not lubricating oil. The test procedure explained in this document...

This document specifies tolerances on form and position as well as the surface roughness of shafts, flanges and thrust collars as used in plain bearing units. It is applicable to journal or thrust plain bearing units or to a combination of both, installed either horizontally or...

Specifies shapes and sizes of cylindrical and conical shaft ends with keyways in diameters 6 mm to 630 mm inclusive. Provision is made for both long and short series and for external and internal screw threads for retaining matching parts by means of nut or screw.

1.1 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 MS51962 inner...

This document specifies the requirements for an engine bearing test rig that uses an actual connecting rod to determine plain bearing performance in automotive engines, evaluating fundamental bearing properties such as seizure resistance, wear resistance, fatigue resistance and...

This document specifies dimensions for lubrication holes, grooves and pockets for bearing bushes. These dimensions can be entered, for example on drawings, using the designation examples. Their use depends in particular on the specific operating conditions. In addition, it enables the user...

This document specifies parameters for the hardness testing of compound materials for plain bearings made from steel and bearing metal with bearing metals based on copper and aluminium, manufactured by casting, sintering or bonding. It represents a supplement to the existing...

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 document specifies the testing and evaluation method of rolling bearing grease noise in accordance with the method BQ+.

This document specifies the testing and evaluation method of rolling bearing grease noise in accordance with the method MQ.

This document specifies the testing and evaluation method of rolling bearing grease noise in accordance with the method NQ.

This Technical Report gives recommendations for automotive crankshaft bearing environments. It specifies the various dimensions and conditions that most engine manufacturers can achieve with current production machinery in order to produce crankshaft bearing environments, which,...

1.1 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 MS51962 inner...

This part of ISO 12240 specifies dimensions, tolerances and radial internal clearances for various dimension series of spherical plain bearing rod ends. The dimensions and tolerances specified in this part of ISO 12240 have been selected to permit the design and use of...

This document describes a method for comparing the performance test results of foil journal bearings, which are lubricated by air (gas) and supported by the gas-dynamic force generated via the rotations of the rotating shaft. The test procedure proposed in this document aims to predict and...

This document specifies dimensional characteristics, nominal boundary dimensions and tolerance values for needle roller bearing track rollers, yoke and stud types.

This document specifies a method for the determination of the endurance limit in fatigue of plain strips of multilayer bearing materials. Additionally, it provides the opportunity of studying the influence on the strips of hydraulic pressure and variable temperature.
