Bevel Gear Manufacturer in Türkiye
We manufacture straight bevel gears, spiral bevel crown wheels and bevel pinion shafts for angle drives, axles and gearboxes – supplied as matched sets with the contact pattern checked.

- 90°typical shaft angle
- Straightand spiral bevel
- Setsmatched gear and pinion
- 3.1material certificates
Power Transmission Around a Corner
Bevel gears transmit motion between intersecting shafts, usually at 90°. Their teeth are cut on a cone, and gear and pinion only work properly as a pair – which is why bevel gears are always made, checked and supplied as matched sets.
Nika Gears produces straight bevel gears for moderate speeds and spiral bevel gears for higher speeds and loads, including bevel pinions cut integral with the shaft.

Questions About Bevel Gears
Do bevel gears have to be replaced in pairs?
Yes. Gear and pinion are checked together, so we always manufacture and supply bevel gears as a matched set.
Straight or spiral bevel?
Straight bevel gears are simpler and suit lower speeds. Spiral bevel gears run smoother and quieter and carry more load at higher speeds.
Can you make a bevel pinion on the shaft?
Yes. Bevel pinion shafts are turned, cut and hardened as one part – see also pinion shafts.
Can you copy a worn bevel set?
Often yes, from the sample and its mating gear. We measure both, prepare drawings for approval and manufacture a new matched set.
Straight and Spiral Bevel Gears: A Buying Guide
Bevel gears turn a drive through an angle – most often 90° – by meshing two conical gears whose axes intersect. They are found in right-angle gearboxes, vehicle and machine axles, agricultural PTO drives, mixers and machine tools.
Straight bevel gears
Straight bevel gears have teeth that run straight towards the cone apex. They are simple to produce and generate modest axial forces, which suits slower drives, differentials and agricultural machinery. Many straight bevel pinions are cut directly on their shafts – see our pinion shafts.
Spiral bevel gears
Spiral bevel gears have curved teeth that engage gradually, like helical gears on parallel shafts. They run quieter and carry more load at higher speeds, which makes them the standard in axle drives and high-performance angle gearboxes.
Why bevel gears come in pairs
The tooth geometry of a bevel gear is generated together with its mate, and the contact pattern depends on both parts and their mounting distances. We therefore manufacture, check and pack gear and pinion as a matched set, and record the mounting distance and backlash for assembly.
Materials and heat treatment
Most bevel gears are case-hardened steels such as 16MnCr5 or 18CrNiMo7-6, carburised to a specified case depth and hardness. Larger, slower bevel gears may be through-hardened 42CrMo4. All material is traced to EN 10204 3.1 certificates.
Alternatives
If you need a high reduction ratio at 90°, a worm gear set may be more compact. If shafts are parallel, use spur or helical gears. As a bevel gear manufacturer in Türkiye we can advise – send your drawing or sample.
