A Gear Manufacturer Built for European Machinery Builders
Nika Gears has produced industrial gears in İzmir since 2004. It has one job: make custom gears and shafts to the customer's drawing, inspect them properly and deliver them to European plants with the documents incoming inspection expects.

What Does Nika Gears Produce?
We manufacture spur gears, helical and double helical gears, bevel gears, worm gears, planetary gear sets, internal gears, gear racks and the shafts that carry them. Every part is built to the customer's drawing and specification – module, profile shift, tooth count, material, heat treatment and accuracy grade.
Our customers are machinery builders, gearbox makers and maintenance teams who need a reliable gear manufacturer in Türkiye: one contact who reads the drawing, asks the right questions, produces the parts and ships them with traceable documents.
Nika Gears is the gear company of the Nika group, producing gears since 2004. Our sister company Nika Steelworks handles steel fabrication, welding and large CNC machining, so a gearbox housing or machine frame can be produced alongside the gears.

Three Things Every Order Gets
Gear buyers do not need slogans. They need parts that fit, arrive on time and come with paperwork that passes incoming inspection.

Material You Can Trace
Every bar and forging is matched to its mill certificate and heat number before machining starts. The heat number follows the part through production.
- EN 10204 3.1 certificates
- Heat numbers marked on blanks
- Material grade checked on arrival

The Right Process for the Part
Blank turning, hobbing or shaping, hardening and grinding are planned per drawing. A ground pinion and a large hobbed gear follow different routes.
- Hobbing, shaping, rack milling
- Case hardening, induction, nitriding
- Profile and worm grinding

Checked Before It Ships
Gear geometry, hardness and dimensions are measured and reported. You receive the reports you asked for, not a generic certificate.
- Gear measurement and runout
- Hardness and case depth
- CMM dimensional reports
Why Buy Gears from Türkiye?
Türkiye has a long tradition of industrial gear cutting, and our machine park includes hobbing machines, gear shapers and grinders from builders such as Pfauter, Liebherr, Lorenz, Reinecker, Niles and Maag. We work to DIN and ISO standards that European engineers already use on their drawings.
From İzmir, road freight reaches Central Europe in days, and engineering questions are answered in the same working day and the same time zone. That makes Nika Gears a practical choice for spur gears, helical gears and gearbox components that are expensive or slow to source elsewhere.
- DIN 3962 / ISO 1328 gear accuracy as specified
- DIN 5480 and DIN 5482 splines
- Export packing and EU delivery

From Drawing to Delivery
The same five steps for a single gear or a repeat series.
- Drawing reviewWe check the gear data, tolerances, material and heat treatment, and ask before we quote.
- QuotationPrice, lead time, processes and inspection scope in one offer.
- ManufacturingBlank preparation, gear cutting, hardening and finishing to drawing.
- InspectionGear measurement, hardness, CMM and material traceability before release.
- DeliveryPreserved, crated and shipped with documents to your plant.

Gears and Steel From One Group
Gearboxes and drive systems need housings, frames and machined steel parts as well as gears. Nika Steelworks produces them in İzmir:
- Welded gearbox housings and machine frames
- CNC machining of large steel parts
- The Nika Steelworks machine park

Are you ISO certified?
Our gears are produced under an ISO 9001 certified quality management system. A copy of the certificate is available on request, and material is supplied with EN 10204 3.1 certificates. See our quality page.
Nika Gears: Custom Gear Manufacturing From İzmir
Nika Gears is a Turkish gear manufacturer based in Menderes, İzmir. We produce custom gears, pinions and shafts to customer drawings for machinery builders across Europe. Our range covers the gear types found in most industrial drives, from small precision pinions to gears up to Ø1,800 mm and module 30.
Why a dedicated gear company
Gear manufacturing is a discipline of its own. Hobbing, shaping, grinding and hardening interact – a tooth profile that is correct before hardening can move out of tolerance after it. A gear company plans for that from the start: the right stock allowance, the right heat-treatment route, and grinding where the accuracy grade calls for it. That is the knowledge Nika Gears brings to every order.
What we manufacture
Our main products are spur gears, helical gears, herringbone and double helical gears, bevel gears, worm gears, planetary gears, internal and ring gears, gear racks, pinion shafts, splined shafts, transmission shafts, drive shafts and gearbox components. Quantities range from a single gear to repeat series for OEM production. Replacement gears made from a worn sample are one of our services.
Quality and documentation
Gears are produced under an ISO 9001 certified quality management system and supplied with EN 10204 3.1 material certificates. Gear geometry, hardness and dimensions are measured before release, and the reports travel with the shipment. Our quality page lists the inspection scope in detail, and the machine park page lists our hobbing, shaping, grinding and machining capacity.
Industries we serve
Our gears run in industries where downtime is expensive: mining and quarrying, steel and metal processing, power generation, recycling and wastewater treatment, construction machinery, marine equipment, food and beverage, sugar processing, plastic and rubber, chemical plants and general industrial machinery.
