Full title and description
Plain bearings — Sintered bushes — Dimensions and tolerances. This International Standard specifies dimensional and tolerance requirements for sintered (porous, self-lubricating) plain bearing bushes in common configurations (cylindrical, flanged and spherical) used in general engineering and machinery design.
Abstract
This document gives the dimensions and tolerances applicable to sintered bushes for defined ranges of inside diameters and types (cylindrical, flanged and spherical). It standardizes nominal sizes, limit deviations and tolerance zones to ensure interchangeability and repeatable manufacturing and inspection.

Scope
ISO 2795:2020 specifies the dimensions and tolerances applicable to sintered bearing bushes for the following inside-diameter ranges: cylindrical bearings 1 mm to 60 mm; flanged bearings 1 mm to 60 mm; spherical bearings 1 mm to 20 mm. The standard covers nominal sizes, limit deviations and tolerance zones necessary for design, manufacture and inspection of these types of sintered plain bearings.
Key topics and requirements
- Definition and designation of sintered bush types (cylindrical, flanged, spherical).
- Nominal inside-diameter series and permitted inside/outside dimensional limits.
- Tolerance zones and limit deviations for bore and outer dimensions to ensure interchangeability.
- Dimensional tables, nominal size lists and example tolerancing practices for manufacturing and inspection.
- Guidance for application of the tolerances to typical sintered bearing geometries and flanges.
Typical use and users
Design engineers, bearing and component manufacturers, quality and inspection personnel, procurement specialists and standards librarians use this standard. It is referenced when specifying sintered bush dimensions on drawings, when setting production tolerances and when carrying out dimensional inspection to ensure replacement/fit with mating shafts and housings.
