About Hatve Gear Industry - Gear Supplier in Turkey

Turkey‑based Hatve Gear Industry lists seven active product entries in its catalogue. The portfolio includes a differential crown wheel pinion gear, a differential spider gear set, a differential spider gear case, a differential rear axle shaft, a differential pinion output flange, a spiral bevel gear and a spiral bevel gearbox. Each item is classified under gear and drivetrain components, a segment commonly coded under HS chapter 84 (particularly 8483 for gears and 8484 for gearboxes). The supplier is recorded as an imported tier with a harbor trust tier, indicating it operates through Turkish export channels to international buyers.

The product set reflects typical mechanical transmission parts used in automotive rear‑axle assemblies and industrial gearboxes. Items such as the differential crown wheel pinion gear and the rear axle shaft are standard inputs for rear‑wheel‑drive differentials, while spiral bevel gears and gearboxes are employed in power‑train direction change applications. The catalogue does not specify material grades, but the listed components align with the conventional steel‑based gear families exported from Turkey. The active count of seven products provides a concise yet focused offering for buyers seeking specific drivetrain elements.

Product Range and Specialties of Hatve Gear Industry

The catalogue enumerates two differential gear families (crown wheel pinion gear, spider gear set and case, rear axle shaft, pinion output flange) and two spiral bevel families (gear and gearbox). In the gear manufacturing industry, such components are typically produced from alloy steels such as 8620 or 8625, heat‑treated to achieve surface hardness in the range of 55‑62 HRC. Standard gear accuracy grades follow ISO 1328, with grades 4 - 6 being common for automotive differentials and grades 7 - 9 for precision industrial applications. Spiral bevel gears often meet ISO 1328 grade 5 or higher and may be supplied with a lead angle of 45° for 90° power transmission. Gearboxes are usually delivered as fully assembled units, tested for torque capacity and noise levels, and may be coated with zinc or phosphate for corrosion protection.

Trade and Export Information - Hatve Gear Industry

Turkish gear manufacturers generally ship to automotive OEMs and tier‑1 suppliers in Europe, the Middle East and North Africa, where demand for rear‑axle components is strong. HS code 8483 covers gears and shafts, while HS code 8484 includes gearboxes; customs inspections frequently require a material certificate and a compliance declaration with standards such as ISO 9001. Buyers often request evidence of heat‑treatment processes and dimensional inspection reports. Common Incoterms for Turkish gear exports are FOB Istanbul Port or CIF Mediterranean ports, with packaging in wooden crates or steel drums to protect gear teeth during sea freight. Turkey’s automotive parts sector benefits from a well‑developed logistics network and a national export strategy that emphasizes high‑precision steel components.

Sourcing from Hatve Gear Industry - Buyer Guidance

When sourcing differential and spiral bevel components from Hatve Gear Industry, buyers should request a mill test report (MTR) confirming chemical composition and hardness, as well as a gear inspection certificate showing tooth profile, runout and ISO 1328 grade. Confirmation of heat‑treatment cycles and surface coating specifications helps verify durability for heavy‑duty applications. It is advisable to obtain a sample or a small‑batch trial to assess fitment with existing axle housings, and to verify that packaging meets ISO 1161 standards for wooden palletisation. Buyers should also confirm that the supplier can provide ISO 9001 certification or equivalent quality system documentation before committing to larger orders.

What types of differential components does Hatve Gear Industry list?

The catalogue includes a differential crown wheel pinion gear, a spider gear set, a spider gear case, a rear axle shaft, and a pinion output flange, all of which are standard parts for rear‑axle differentials.

Are spiral bevel gears and gearboxes part of the product range?

Yes, the supplier lists a spiral bevel gear and a spiral bevel gearbox, which are used for 90° power transmission in automotive and industrial applications.

Which HS codes are relevant for these gear products?

Differential gears and shafts fall under HS 8483, while the spiral bevel gearbox is classified under HS 8484, the standard codes for gears and gearboxes.

What material specifications should a buyer verify?

Buyers typically request confirmation that the gears are made from alloy steel (e.g., 8620/8625), heat‑treated to 55‑62 HRC, and that they meet ISO 1328 gear accuracy grades.

What documentation is commonly required before purchase?

A mill test report, gear inspection certificate showing tooth profile and runout, and evidence of ISO 9001 or equivalent quality system are standard documents.

What are typical packaging and shipping terms for these items?

Gear components are usually packed in wooden crates or steel drums, shipped FOB Istanbul Port or CIF to Mediterranean ports, with dimensions secured to prevent movement during transit.

Which markets typically import Turkish differential gears?

European automotive manufacturers, Middle‑East vehicle assemblers, and North African tier‑1 suppliers are common importers of Turkish differential and bevel gear products.

What sample or trial procedures are advisable?

Requesting a functional sample or a small‑batch trial allows verification of fit, tooth geometry and surface finish before scaling up the order.
