BS ISO 12130-1:2021

This standard BS ISO 12130-1:2021 Plain bearings. Hydrodynamic plain tilting pad thrust bearings under steady-state conditions is classified in these ICS categories:

• 21.100.10 Plain bearings

This document specifies a calculation method for oil-lubricated hydrodynamic plain bearings with complete separation of the thrust collar and tilting pad thrust bearing surfaces by a film of lubricant.

This document applies to plain thrust bearings with tilting-type sliding blocks (tilting pads), where a wedge-shaped lubrication clearance gap is automatically formed during operation. The ratio of width to length of one pad can be varied in the range B/L = 0,5 to 2.

This document is not applicable to heavily loaded tilting pad thrust bearings.
