Full title and description
STB DIN 506: 2004-09 — Driving components: cap-bearings and half-bearings (bearing shells) — bearing fastening with four screws. This document is the September 2004 edition of DIN 506 and specifies dimensional, material and fastening requirements for cap/half plain bearings secured with four screws.
Abstract
DIN 506:2004-09 defines the form, dimensions, designation and marking of cap-bearings and half-bearings (bearing shells) that are fastened using a four-screw arrangement. The standard covers nominal sizes, tolerances, material designation and marking requirements necessary for interchangeability and correct mounting of plain bearing shells in mechanical assemblies.

Scope
This standard applies to cap-bearings and half-bearings (bearing shells) that are intended to be fastened by four screws. It standardises dimensions and designation, specifies acceptable materials and marking, and includes normative references and relevant tolerances so that bearing shells from different manufacturers are mutually interchangeable and can be mounted reliably in machines and gearboxes. The standard is primarily limited to the mechanical and dimensional requirements for the four-screw fastening variant of bearing shells.
Key topics and requirements
- Dimensional specifications and nominal sizes for cap-bearings and half-bearings (bearing shells).
- Designation and labelling rules to identify bearing shells and their orientation.
- Material designation and basic material requirements for bearing shells used with four-screw fastening.
- Requirements for the four-screw fastening arrangement (hole positions, clearances and basic mounting geometry).
- Tolerances and marking to ensure interchangeability and correct assembly.
Typical use and users
Used by mechanical designers, bearing manufacturers, maintenance engineers, quality assurance personnel and technical libraries. Typical applications include engine and gearbox assemblies, industrial machinery, agricultural equipment and any mechanical system that uses plain bearing shells secured by four screws where standardised dimensions and fit are required.
Related standards
DIN 506 is referenced and used alongside other bearing and casting standards and handbooks. Relevant related documents include entries in DIN Handbook 126 (plain bearings), various DIN/ISO standards addressing bearing materials, tolerances and mounting (examples include standards for lubrication holes, tolerances for castings and plain bearing testing methods). The 2004 edition supersedes DIN 506:1973-07.
