Custom ratchets and jaw clutches
Commercial Gear & Sprocket manufactures custom ratchets and jaw clutches for OEMs, machine builders, replacement applications and industrial equipment — combining dedicated ratchet and clutch cutting equipment, CNC machining, secondary operations and inspection.
Ratchets and jaw clutches made to your specifications
Ratchets and jaw clutches are specialized mechanical components for equipment that needs controlled engagement, indexing, holding or torque transmission.
We manufacture custom ratchets and jaw clutches to your drawings, component geometry, dimensions, material, bore configuration, tolerances and quantity — with involute gear milling, ratchet cutting and clutch cutting among our specialized capabilities.
Ratchet and jaw clutch size range
Ratchet diameter
Up to 30″
Custom ratchets manufactured up to 30 inches in diameter.
Jaw clutch diameter
Up to 24″
Custom jaw clutches manufactured up to 24 inches in diameter.
Additional machining
As required
Bores, shafts, keyways and holes to the part requirements.
Product type
Custom ratchets & jaw clutches
Manufacturing
To your requirements
Tooth profile, number of teeth or jaws, bore configuration, shaft features, material, heat treatment, finish, tolerances, mating components and inspection should be shown on your drawing or reviewed during quotation.
How we manufacture ratchets and jaw clutches
Dedicated ratchet and clutch cutting machinery with CNC machining, secondary operations, finishing and inspection — chosen around geometry, tooth or jaw form, diameter, material, quantity and the mating part.
Whiton #1 and Whiton #2 machines cut ratchet teeth and involute gear forms, for ratchets up to 30″ diameter.
Whiton equipment with face gear attachments cuts custom jaw clutches up to 24″ diameter to your jaw configuration.
CNC turning centers with live tooling and 4-axis vertical machining for bores, shafts, keyways and holes.
Chamfering, automatic deburring, heat treatment coordination, metal finishing and inspection.
Dedicated cutting equipment
Ratchet teeth and clutch jaws need specialized cutting. Our Whiton machines are set up specifically for involute gear milling, ratchet cutting and clutch cutting, with face gear attachments for jaw forms.

Ratchet and clutch design
A ratchet lets motion pass one way and locks it the other; a jaw clutch engages or disengages a drive through interlocking jaws. Both rely on tooth or jaw geometry that suits the mating part exactly.
What we confirm from your drawing:
Profile angle, number of teeth or jaws and tooth-top flat.
Teeth on-center or off-center relative to the bore.
The pawl or mating clutch half the part engages.
Bore, keyway and shaft features for the assembly.
CNC machining
Machining before or after the teeth or jaws are cut, in the same job.
Diameters, faces and hubs turned to size.
Milled features produced to the drawing.
Bores machined for the required fit.
Shafts machined and bores opened up as needed.
Keyways cut to your specification.
Holes and other customer-specified features.
Finishing & secondary operations
Dedicated chamfering and automatic deburring equipment, plus outside sources for heat treatment and metal finishing.
Tooth and jaw edges chamfered after cutting.
Burrs removed from teeth, jaws and machined features.
Specified heat treatment sourced and coordinated.
Finishes applied as your drawing requires.
Critical dimensions verified to the drawing.
Tooth form checked on an optical comparator.
Prototype to production
Prototype ratchets and clutches for new designs.
Replacement ratchets and jaw clutches for existing equipment.
Components made to your existing drawings, from your blanks or ours.
Short runs through production-volume OEM orders.
Ratchets and jaw clutches for industrial equipment
Custom ratchets and jaw clutches are used in machinery where component geometry and engagement must match a specific mechanical application. Send the drawing, mating-part information, material, quantity and operating requirements with your quote request.
Ratchets that lock motion in one direction.
Controlled step-by-step indexing.
