Question: Which standard for controlling the clearance in sliding bearings is the most authoritative?
Thread Content
It seems that 1.5–2‰ is the commonly used value. There are several types of sliding bearings, and I wonder if there are different range of clearances – I would appreciate advice from experts.
This should be the approximate range of clearance; for each bearing specifically, it is still necessary to refer to the manual
The sliding bearings of conventional units can meet the above requirements; even with slightly less optimal performance, it has little impact. For important equipment, first consider the requirements of the manufacturer and the drawings.
Generally, it is done based on empirical values; for more precise applications, there are specific requirements, and it’s sufficient to follow those requirements! If we have to ask which authority is the most authoritative, it’s definitely the requirements for design and manufacturing!
Proceed in accordance with the data requirements or drawing specifications provided in the manufacturer’s instructions; if none are available, handle it in compliance with the relevant standards. Generally, the gap is set at its maximum allowed value to prevent the tiles from burning out.
Generally, repairs should be carried out according to the manufacturer’s repair manual
The specified clearance value for bearings is empirical reference data.
