ISO 12043:2007 specifies the minimum chamfer dimensions for loose rib and non-rib sides of single-row cylindrical roller bearings of diameter series 0, 2, 3, and 4 (except dimension series 24) as specified in ISO 15. Indication is given for those minimum chamfer dimensions that are identical to those in ISO 15.

Overview

ISO 12043:2007 - "Rolling bearings - Single-row cylindrical roller bearings - Chamfer dimensions for loose rib and non-rib sides" specifies the minimum chamfer dimensions for the loose‑rib and non‑rib faces of single‑row cylindrical roller bearings. It applies to diameter series 0, 2, 3 and 4 (except dimension series 24) as defined in ISO 15. Minimum chamfer values are given in a tabular form (Table 1) in millimetres, and the Standard indicates where those minimums match the chamfer values already published in ISO 15. Maximum chamfer limits are referenced to ISO 582.

Key topics and requirements

Scope and applicability: Minimum chamfer dimensions for single‑row cylindrical roller bearings (diameter series 0, 2, 3, 4; excluding series 24).

Chamfer symbols and terms: Uses symbols defined in ISO 15241 and terminology from ISO 5593 (for example, r, r1s min).

Dimensional data: Table 1 provides the nominal minimum chamfer dimensions (r and r1s min) in millimetres for the covered diameter series and bore sizes.

Design coverage: Values are valid for both standard design and E‑design cylindrical roller bearings (E‑design indicates reinforced roller/cage assembly for increased radial load capacity).

Cross‑references: Points out when chamfer minima are identical to those in ISO 15 and refers to ISO 582 for maximum chamfer dimensions.

Normative references: ISO 15, ISO 582, ISO 5593, ISO 15241.

Practical applications

Ensures consistent bearing chamfer geometry to prevent interference with mating components (ribs, shoulders, housings) during assembly.

Reduces risk of edge stresses, improper seating, or roller/rib contact that could shorten bearing life.

Guides bearing designers and manufacturers when specifying internal edge radii for single‑row cylindrical roller bearings.

Helps quality control and inspection teams verify minimum chamfer compliance as part of incoming or final inspection criteria.

Useful for procurement and engineering teams specifying bearings for machinery where shaft shoulders or housing ribs interact with bearing faces.
