SIZE REFERENCE / YZEFY SPROCKETS

10B sprockets

10B sprockets are selected for European industrial drives, conveyors, packaging, woodworking and replacement equipment. The 10B designation identifies the ISO 606 B-series chain family, but it does not finish the sprocket specification. Confirm strand, teeth, bore, keyway, hub and available axial space before ordering. 10B is identified by the B-series dimensions first. Teeth, strand and the shaft interface are then selected for the actual machine.

A standard request can start with the chain marking and required tooth count. A custom or replacement request should include the applicable drawing, sample, measured sprocket or shaft information. The chain and the shaft interface need to be checked as one assembly.

Chain & Size Reference

These values identify the mating chain. They are not finished sprocket dimensions. Pitch diameter, outside diameter, tooth width, bore and hub dimensions depend on the tooth count, strand arrangement and machine drawing.

Simplex / Duplex / Triplex

A simplex sprocket carries one chain row. Duplex and triplex versions carry two or three rows and use different transverse spacing and total tooth width. Include the full strand suffix with 10B. The base designation alone is not enough for a multi-strand part.

Available Sprocket Configurations

  • Type A plate sprockets for compact layouts or separate-hub assemblies.
  • Type B sprockets with a hub on one side.
  • Type C sprockets with hubs on both sides or a wider shaft interface.
  • Idler, split, weld-on, bushing-mounted and other drawing-defined forms.

Do not assign a tooth count from the chain size alone. Confirm driver and driven teeth in the RFQ or drawing.

Bore & Hub Options

Specify pilot bore, finished bore, keyed bore, set screw, bushing, split hub or another shaft connection. Include shaft diameter, keyway size and position, hub side, hub length, face width and axial clearance. For a replacement, measure the shaft and keyway separately from the worn sprocket. If a taper-lock or QD arrangement is used, send the bushing reference and assembly space.

Materials

Carbon steel is used for many general industrial drives. Alloy steel can be considered for higher load, shock or wear requirements. Stainless steel suits corrosion, washdown and cleaning exposure. Cast iron, aluminum and engineering plastics may fit specific low-load or weight-sensitive designs. State the material grade, supply condition and certificate requirement in the RFQ.

Heat Treatment & Surface Treatment

Tooth hardening, induction hardening or carburizing may be specified when the drawing or application requires greater tooth wear resistance. Protective surface treatment can be considered for corrosion, storage or washdown conditions. Include hardness, case depth, treated area, surface finish and inspection method when those values are controlled by the purchase specification.

Custom 10B Sprockets

Send the ISO series, chain reference, number of teeth, strand, bore, keyway, hub dimensions and quantity. Add material, heat treatment, surface treatment, tolerances, marking and inspection requirements from the drawing. For sample-based work, include the chain marking, tooth count, pitch, roller diameter, inner width, face width and shaft measurements. Application speed, load, center distance and operating environment can resolve details that a worn sample cannot show.

Replacement Sprockets

A replacement 10B sprocket should be checked against the mating chain and shaft, not copied from worn tooth tips. Send the old chain marking, tooth count, bore, keyway, hub, face width, photos and any part number. If the failure involved chain elongation, poor alignment, inadequate lubrication or contamination, inspect the chain and mating sprocket before replacing one part.

Applications

10B sprocket requests commonly come from European industrial drives, conveyors, packaging, woodworking and replacement equipment. The application helps define the review, but it does not choose the tooth count or shaft connection. Load, speed, chain line, environment and mounting space still belong in the specification.

Standard & Compatibility Notes

10B and 10A share a listed pitch but use different inner widths and series geometry. The B-series suffix must remain visible in the product record. The series suffix must stay in every RFQ and drawing. Compare pitch, roller diameter, inner width, strand spacing, tooth form and shaft interface before approving a substitute.

How to Select

  1. Confirm ISO 606, the B-series suffix and the complete 10B chain reference.
  2. State simplex, duplex or triplex and the complete strand suffix.
  3. Record driver and driven teeth, speed ratio, center distance and chain line.
  4. Check pitch, roller diameter, inner width and transverse spacing.
  5. Select Type A, Type B, Type C or another drawing-defined form.
  6. Specify bore, keyway, locking method, hub dimensions and axial clearance.
  7. Add material, treatment, finish, quantity, inspection and drawing revision.
  8. Send a sample or measured photo if any original dimension is uncertain.

FAQ

What is the 10B pitch?

The 10B reference row lists a 15.875 mm pitch.

Why must 10B stay separate from 10A?

Their roller and inner-width dimensions differ, so a pitch match is not a sprocket fit confirmation.

Can 10B sprockets be made for duplex chain?

Yes, if the complete chain suffix and transverse spacing are supplied.

Which documents help with a 10B RFQ?

A current or legacy drawing, chain marking, shaft measurements and a photo of the existing assembly are useful.

Request a Quote for 10B Sprockets

Send the ISO series, chain reference, number of teeth, strand, bore, keyway, hub, quantity and application. For custom or replacement work, attach the drawing, sample photo, old sprocket dimensions or existing part number. This prevents a shared-pitch comparison from being treated as a complete fit confirmation.
