(Practice)Standard Practice for Damage Prevention of Bearings, and Bearing Components Through Proper Handling Techniques
Standard Practice for Damage Prevention of Bearings, and Bearing Components Through Proper Handling Techniques
SCOPE
1.1 This practice covers requirements for the handling of all bearings and bearing components.
1.2 This is a general practice. The individual bearing handling requirements shall be as specified herein or as specified in the contract or purchase order. In the event of any conflict between requirements of this practice and the individual bearing requirements of an OEM drawing, procurement specification, or other specification, the latter shall govern. Many companies, organizations, and bearing users have excellent facilities, equipment, and knowledgeable personnel for handling bearings. The thrust of this practice is for users that do not have this knowledge of bearings.
1.3 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.
