Abstract

Overview

ISO 13012-2:2018 - Rolling bearings - Accessories for sleeve type linear ball bearings - Part 2 - specifies boundary dimensions, geometrical product specifications (GPS) and tolerances for accessories used with series 5 sleeve type linear ball bearings. Published as the second edition in 2018, this machine-element geometry standard defines the nominal sizes and tolerance/positioning rules for housings, shaft support rails, flanged shaft support blocks and solid or tubular shafts used with ISO 10285 sleeve type linear ball bearings.

Key topics and technical requirements

Scope of parts covered
- Closed and adjustable flangeless housings (series 5)
- Open and open-adjustable flangeless housings (series 5)
- Standard-height shaft support rails
- Flanged shaft support blocks
- Solid and tubular shafts for series 5 bearings
Boundary dimensions and nominal features
- Seating diameter (D), overall widths/heights (A, H), housing lengths (L), bolt centre distances (J), bolt/hole diameters (N), shaft centreline heights, etc. (referenced in figures and tables)
Geometrical Product Specifications (GPS)
- Position tolerances (symbols p1, p2, p3), angular features (α, β), and ISO GPS-compliant tolerance indications
- Geometric form requirements and two-point size rules per ISO 14405-1
Shaft material and treatment guidance
- References for surface-hardened and through-hardened shafts and layer thickness measurement (ISO 18203)
- Guidance on chamfers, shaft length tolerances, surface roughness and tolerance classes
Measurement and conformity
- GPS rules (ISO 8015) and decision rules (ISO 14253-1) apply
- Measurement uncertainty considerations per ISO 14253-2

Applications and who uses it

ISO 13012-2:2018 is intended for:

Bearing and accessory manufacturers (for consistent production and interchangeability)
Mechanical designers and machine builders specifying linear motion systems (automation, robotics, CNC machines, conveyors)
Quality, metrology and inspection labs verifying dimensions and positional tolerances
Procurement and regulatory teams requiring standardized part descriptions and conformity evidence

Using this standard helps ensure smooth, accurate, low-friction linear motion by enabling correct selection and matching of housings, shafts and supports to sleeve type linear ball bearings.
