Scope

Scope: This document specifies the test procedures for dustproofness, grease leakage, and temperature rise of general-purpose sealed deep groove ball bearings (with sealing rings on both sides or dustproof covers on both sides) whose dimensions comply with GB/T 276's diameter series 0, 2, and 3, with a nominal inner diameter of 5 mm ≤ d ≤ 60 mm and a nominal outer diameter of D ≤ 130 mm (hereinafter referred to as sealed ball bearings). Bearings of other types, size series, and size ranges may be used as a reference. This document applies to the test methods and procedures for dustproofness, grease leakage, and temperature rise of sealed ball bearings conducted on a sealing performance testing machine.
