Description
The KAF Flanged Boss is a precision-machined locating and support component featuring a central bore and an extended integral flange. The flange provides a defined seating face and increased support area, while the machined boss controls the position of the mating pin, shaft, fastener, or sleeve. When manufactured to the approved dimensions, it helps maintain concentricity, alignment, and stable load transfer through the assembly.
Application and function
Used as a locating, mounting, spacing, bearing, or reinforcement feature within selected Honda motorcycle components where an integral flange is required to control axial position or increase the seating area.
Design features and benefits
Integral flange for positive seating; accurately machined central bore; controlled boss diameter and projection; defined mounting faces; supports correct centring, axial location, structural stability, and repeatable assembly.
Available variants
Custom bore sizes, boss diameters, flange diameters, flange thicknesses, projections, mounting details, chamfers, grooves, material grades, hardness levels, and protective finishes can be considered from an approved technical reference.
Material and finish
Precision-machined engineering-grade metal construction. The exact alloy, hardness, heat treatment, surface condition, corrosion protection, and lubrication requirements must be confirmed against the approved drawing, sample, and purchase specification.
Dimensions and tolerances
Produced to an approved drawing, master sample, or dimensional inspection schedule. Diameter, bore, length, flange or collar thickness, concentricity, runout, surface finish, and working clearances are confirmed before production; no unverified nominal dimensions are assumed.
Quality control
Inspection may include bore, boss and flange diameters, flange thickness, projection, concentricity, runout, perpendicularity, flatness, surface finish, edge condition, hardness, and visual quality according to the agreed control plan.
Packaging
Clean, dry, protective bulk or partitioned packaging is available, with rust-prevention treatment, labels, batch identification, and buyer-specified domestic or export packing confirmed in the quotation.
Information required for quotation
Provide the motorcycle model and year, installation position, bore and boss diameters, flange diameter and thickness, projection length, mating-part details, required fit or clearance, load direction, photographs, drawing or sample, and order quantity.
Model and dimensional verification required. Confirm the motorcycle model, model year, engine or chassis variant, installed position, mating-part dimensions, drawing, sample, or reliable part reference before ordering.
