SELECTION FOCUS
Questions that change the direction.
- Machine maker and exact 4B model or existing approved sample
- Blue-steel sheet versus a protected-contact construction
- Workpiece count, loading method and minimum web width

4B Blue-Steel Lapping Carriers
A blue-steel carrier configuration developed for a confirmed 4B double-side machine and its actual workpiece layout.
HOW THIS PRODUCT IS JUDGED
Connect the physical product to its process function.
4B is a machine-family label, not a universal tooth drawing. The outside gear, plate opening, carrier count and workpiece envelope need to be reconciled with the exact machine before a sheet thickness or pocket pattern is released.RFQ & DRAWING FIELDS
Evidence needed before release.
- Outside diameter, tooth count, pitch/profile and centre geometry
- Steel grade, thickness range, flatness and burr direction
- Pocket outline, workpiece clearance and edge finish
- First-article fit, tooth engagement and wet-process trial
PRODUCT REFERENCE
Confirm the configuration for your part.

A practical review sequence for this product family.
Material choice
Specify the alloy or review candidate materials against stiffness, wear and the actual wet chemistry.
Drawing definition
Confirm carrier outside diameter, tooth form, pocket map, thickness and the agreed burr limit.
Release checks
Agree the method for thickness and flatness checks, and inspect the pocket and tooth edges before a process trial.
Order-specific dimensions, material grades and acceptance values are recorded in the approved specification. This sequence is selection guidance, not a pre-validated process recipe.
PUBLIC CLAIM BOUNDARY
Typical direction is not a performance guarantee.
Dimensions, materials, removal rate, roughness, life and compatibility are published only when supported by an approved drawing, material record or project-specific validation. Unverified label examples, third-party photographs and customer pricing remain internal references.
