Quick answers to common questions about gear manufacture, materials, tooth forms, tolerances and choosing between standard and bespoke components.
Common choices include case-hardening steels, through-hardening alloy steels, stainless steels, engineering bronzes and engineering plastics. The right material depends on load, speed, duty cycle, environment, wear requirements and whether heat treatment is needed.
Hardening is usually considered when higher surface durability, wear resistance or load capacity is required. Case hardening, nitriding and through hardening are typical options, with the choice depending on material, tooth size, distortion limits and final accuracy requirements.
A drawing is best, but useful gear data can include module or DP, number of teeth, pressure angle, helix angle, face width, bore and mounting details, material, heat treatment, quality grade and any profile or lead modifications.
Manufacturing enquiry guidance →Yes. We can review existing drawings and specifications for manufacture, and can support prototypes, development work, small batches and repeat production.
Standard gears are catalogue products with defined sizes and ratios. Bespoke gears are made to a customer drawing, application requirement or specific gear geometry where a standard part is not suitable.
Inspection can include dimensional checks together with gear-specific measurement such as profile, lead, pitch and runout, depending on the drawing and required quality level.
Gear inspection guidance →Speak with our engineering and sales team about standard products, precision gears, gearboxes, splines or bespoke made-to-drawing manufacture.
Send us your drawing, specification or application details. We can help identify a suitable standard product or the appropriate design and manufacturing route.
