Custom Gear Racks
Gear racks developed for controlled linear motion, mounting, joining, lubrication, and load requirements.
Engineering review
SINOF reviews rack and pinion data together where possible, including mounting datums, segment joints, and inspection criteria.
- Straight and helical rack concepts evaluated
- Segmented rack and joint alignment requirements
- Mounting-hole, datum, and end-machining options
- Matched pinion requirements reviewed
Materials and precision
Pitch, straightness, mounting datum, and tooth-quality requirements are confirmed after drawing review.
- Carbon and alloy steels, subject to wear requirements
- Stainless steel for suitable environments
- Engineering plastics for suitable duty
Customization inputs
- Module or diametral pitch and pressure angle
- Rack length, section, hole pattern, and joint geometry
- Helix angle for helical racks
- Heat treatment and surface protection
Inspection
- Pitch and tooth geometry checks when specified
- Straightness, section, and mounting-datum inspection
- Joint and matched-pinion criteria as agreed
Frequently asked questions
Can long travel be built from rack segments?
Segmented solutions can be reviewed. Joint pitch, end geometry, mounting datum, and installation alignment must be defined.
Should the pinion drawing be included?
Yes. The mating pinion helps confirm tooth system, backlash target, duty, and the most useful inspection criteria.
