Scope

Scope: This document specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of marine water-lubricated bearings (hereinafter referred to as bearings). This document applies to the design, manufacture, and inspection of non-metallic water-lubricated bearings with an inner diameter of 40mm to 2000mm. Main Technical Content: 3.1 Water-lubricated bearings: Bearings that use clean freshwater or seawater as the lubricating medium, with overall structures divided into cylindrical bearings and segmented bush bearings. 3.2 Water-lubricated bush bearings: Bush bearings using clean freshwater or seawater as the lubricating medium, primarily categorized into plastic bush bearings and rubber bush bearings based on material. 3.3 Marine water-lubricated bearings: Water-lubricated bearings used on ships and marine engineering projects. 3.4 Bush bearing type: A bush bearing composed of a bush base and a bush liner, available in assembled or embedded versions. 3.5 Bush support: A supporting body directly connected to the bush liner to provide the required strength and rigidity, made from metallic or non-metallic materials. 3.6 Bush liner: The portion of the bearing that mates with the journal during wear, or the portion of the thrust sliding bearing that mates with the journal support surface, made from non-metallic materials. 3.7 Shelling: The separation phenomenon between the bush liner and the bush base. 3.8 Bush temperature: The temperature measured at corresponding positions on the bush liner or bush base, referred to as "bush temperature," with units in °C. 3.9 Working pressure (specific pressure): The ratio of the bearing's working load to its effective bearing area, expressed in MPa. 3.10 Width-to-diameter ratio: The ratio of the bearing bush width to the journal diameter. 3.11 Radial clearance: The total one-way clearance between the journal and the journal bore. 4 Classificati
