(Specification)Standard Specification for Bearing, Roller, Thrust, Two Channeled Race Surface, Rigid or Flat Seat Type
Standard Specification for Bearing, Roller, Thrust, Two Channeled Race Surface, Rigid or Flat Seat Type
ABSTRACT
This specification covers requirements for rigid or flat seat type, two channeled race surface, thrust roller bearings intended for use in slow rotating or oscillating applications where pure thrust loads are applied. The thrust bearing shall be made of the specified high carbon chromium alloy steel. Requirements for (1) physical properties such as heat treatment, (2) dimensions and mass, and (3) surface finish are specified. Dimensions of retainer type, steering gear service and retainerless type, intermittent operation, are illustrated.
SCOPE
1.1 This specification covers requirements for rigid or flat seat type, two channeled race surface, thrust roller bearings.
1.2 Intended UseThe bearings covered in this specification are intended for use in slow rotating or oscillating applications where pure thrust loads are applied.
1.3 This specification contains many of the requirements of MS17169, which was originally developed by the Department of Defense and maintained by the Defense Supply Center in Richmond. The following government activity codes may be found in the Department of Defense, Standardization Directory SD-1.Preparing ActivityCustodiansReview ActivitiesDLA-GS4Army-ATArmy-MINavy-MCAir Force-84Air Force-99DLA-GS4
1.4 For design feature purposes, this specification takes precedence over procurement documents referenced herein.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
