Описание (английский):

ISO 5753-1:2009 specifies values of radial internal clearance for: - radial contact groove ball bearings, except those for insert bearings; - double-row self-aligning ball bearings; - cylindrical roller bearings; - needle roller bearings, except drawn cup needle roller bearings; - toroidal roller bearings; - double-row self-aligning roller bearings. It gives clearance values for all six types of bearing with cylindrical bore and also for double-row self-aligning ball bearings, cylindrical roller bearings, toroidal roller bearings and double-row self-aligning roller bearings with tapered bore.

Overview

ISO 5753-1:2009 - Rolling bearings - Internal clearance - Part 1: Radial internal clearance for radial bearings specifies standardized values of radial internal clearance (given in micrometres) for several common radial rolling bearing types. It defines clearance values for bearings with cylindrical bores and, for selected bearing types, for tapered bores. This first edition replaces ISO 5753:1991 and extends clearance values to larger bore sizes and additional bore types.

Key topics and technical requirements

Bearing types covered: radial contact groove ball bearings (excluding insert bearings), double‑row self‑aligning ball bearings, cylindrical roller bearings, needle roller bearings (excluding drawn‑cup types), toroidal roller bearings, and double‑row self‑aligning roller bearings.

Bore variations: values provided for cylindrical bores for all listed types; tapered bore clearance values are included for double‑row self‑aligning ball bearings, cylindrical roller bearings, toroidal roller bearings and double‑row self‑aligning roller bearings.

Clearance tables: the standard contains tabulated radial clearance values (by bore diameter ranges and clearance groups such as Group 2, N, 3, 4, 5).

Measurement considerations:

Radial internal clearance is defined as the arithmetical mean of radial displacements between ring extreme positions with no external load.
Actual measurement requires applying a measuring load; because this induces elastic deformation, that deformation must be added to the clearance values specified.
Scatter in repeated measurements is acknowledged; manufacturers should account for this by applying appropriate manufacturing tolerances.

Scope exclusions / references: insert‑bearing clearances are covered in ISO 9628. Measurement methods and related terms are referenced (e.g., ISO 1132‑2 for measurement methods, ISO 1132‑1 and ISO 5593 for terms).

Practical applications and users

Who uses ISO 5753-1:2009 and why:

Bearing manufacturers - to set production tolerances and to specify nominal internal clearances for product ranges.

Design and application engineers - to select appropriate bearing clearances for machine designs where radial clearance affects preload, running accuracy, thermal growth and life.

Quality control and metrology teams - to validate delivered clearances against standardized values and to interpret measurement results (accounting for measuring load deformation).

Maintenance and reliability engineers - to diagnose running issues, specify replacements and determine acceptable clearances for reassembly.

Procurement and specification writers - to reference standardized clearance classes in purchase documents and drawings.
