Overview
ISO 5429:2012 specifies nominal dimensions and limit deviations for coated-abrasive flap wheels with incorporated flanges (version A) or separate flanges (version B) intended for use on stationary grinding machines. This third edition updates the 2005 version by adding additional flap-wheel widths and aligning the dimensional table editorially with ISO 3919. The standard defines how to designate and mark these flap wheels for consistent identification and safe operation.
Key Topics
- Scope and use: Applies to flap wheels fitted with incorporated or separate flanges for stationary grinding machines.
- Dimensions and tolerances:
- Diameter (D) and width (T) combinations are listed in a dimensional table (Table 1).
- Diameter tolerance shown in the document header is D ±1 mm (as specified in the table).
- Bore diameter (H) for version A is indicated but H dimensions are left to the manufacturer’s discretion.
- Designation format:
- Required designation elements: product name, reference to ISO 5429, flange version (A or B), diameter D (mm), width T (mm), and bore H (mm for version A).
- Example: Flap wheel ISO 5429 - A 350 × 75 × 40
- Marking requirements:
- Manufacturer, supplier or trademark
- Dimensions
- Maximum operating speed
- Maximum permissible speed of rotation
- Grit size
- Informative illustrations: A flange sketch is included for information only and does not mandate flange shape or attachment method.
Applications
ISO 5429 is directly relevant to manufacturers, suppliers, quality engineers, procurement professionals, and end-users of coated-abrasive flap wheels who need standardized products for:
- Surface finishing, deburring, blending and edge work on stationary grinding machines
- Ensuring interchangeability and safety through consistent dimensions and marking
- Compliance checks during incoming inspection and quality control
Typical users:
- Flap wheel manufacturers and tool designers
- Industrial buyers and maintenance teams in metalworking, fabrication, and manufacturing shops
- Standards and compliance officers managing abrasive product specifications
