Gear Types We Produce
Spur, helical, double helical, bevel, planetary and ring gears, pinion shafts and splined shafts from recent orders.
Which Gear Type Fits Your Drive?
| Gear type | Best for |
|---|---|
| Spur gears | Parallel shafts, moderate speed, simple and economical |
| Helical gears | Parallel shafts, higher speed and load, lower noise |
| Herringbone / double helical | Very high torque without axial thrust on the bearings |
| Bevel gears | Intersecting shafts, usually 90° |
| Worm gears | High reduction ratios in one stage, self-locking options |
| Planetary gears | High torque density, coaxial input and output |
| Internal & ring gears | Planetary stages, slewing drives, compact layouts |
| Gear racks | Converting rotation into linear motion |
Which Materials, Heat Treatments and Accuracy Grades?
Steel and Bronze
Case-hardening steels such as 16MnCr5, 20MnCr5 and 18CrNiMo7-6; through-hardening steels such as 42CrMo4 and 34CrNiMo6; CuSn12 and CuAl10 bronze for worm wheels.
- Forgings or bar
- EN 10204 3.1 certificates
Hardened to Drawing
Carburising and case hardening, induction hardening, nitriding, or quench and temper – with hardness and case depth reported.
- Surface and core hardness
- Case depth to drawing
Hobbed, Shaped or Ground
Accuracy grade decides the finishing route. Ground gears reach tighter DIN 3962 / ISO 1328 grades than hobbed or shaped gears.
- Profile and lead measured
- Grade confirmed at quotation
What Should a Gear RFQ Include?
A complete enquiry gets a faster and more exact quotation. These five points cover almost every gear and shaft we are asked to make.
- Gear dataModule or diametral pitch, number of teeth, pressure angle, helix angle and hand, face width, profile shift.
- MaterialSteel grade or bronze alloy, and whether the blank is a forging, bar or plate.
- Heat treatmentCase hardening, induction hardening, nitriding or quench and temper, with hardness and case depth.
- AccuracyGrade to DIN 3962 or ISO 1328, and which flanks, bores and seats are ground.
- Quantity and deliveryPieces per order, yearly demand if it repeats, required reports and the delivery address.

Questions About Our Gear Range
Do you sell standard catalogue gears?
No. Nika Gears manufactures custom gears to customer drawings or samples. That includes replacements for gears that are no longer available from the original supplier.
Can you make a gear from a worn sample?
Yes. Send the worn gear or clear photos with the main dimensions. We measure it, prepare a drawing for your approval and then manufacture.
What is the size range?
From small precision pinions up to Ø1,800 mm and module 30. Internal gears up to Ø1,600 mm and module 16.
Do you supply complete gear sets?
Yes – matched pairs, planetary sets and complete gearbox gear sets, inspected and packed together.
A Complete Range of Industrial Gears From One Manufacturer
Industrial drives combine several gear types. A conveyor drive may need a bevel gear stage, two helical stages and a splined output shaft; a mixer may run on a planetary gearbox with an internal ring gear. Nika Gears manufactures all of these, so a complete gear set can come from one source with one set of documents.
Parallel-shaft gears
Spur gears are the simplest and most economical choice for parallel shafts. Helical gears run quieter and carry more load at higher speeds. For very high torque, herringbone and double helical gears cancel the axial thrust that single helical gears put on the bearings.
Angle and worm drives
Bevel gears transmit power between intersecting shafts, usually at 90°. Worm gears give high ratios in a single stage and can be self-locking – useful for hoists, gates and positioning drives.
Planetary and internal gears
Planetary gear sets pack high torque into a compact, coaxial unit. Their ring gears, along with slewing rings and internally splined hubs, are produced on gear shapers as internal gears.
Racks and shafts
Gear racks convert rotation into linear motion. Pinion shafts, splined shafts, transmission shafts and drive shafts carry the gears, and gearbox components such as cluster gears and hubs complete the set.
Every type is made to drawing, inspected and documented. Check our machine park for capacity and quality for inspection scope, or send a drawing for a quotation.
