That's why the enterprise has developed various gear parts processing techniques, formed machine population and tooling backup.
Nowadays JSC EZTM designs, manufactures and supplies the following gears types: special spur gear speed reducers, bevel gear speed reducers, worm gear speed reducers, spiroid gear reducers and cone worm units, weighted from 10 kg to 90 t as well as gear clutches and rim sprockets for drives of rolling, metallurgical, mining and other heavy equipment.

Alloy steel grades (38ХА, 35ХМ, 20ХНЗА, and etc.) are used for production of the gears.
The main types of heat treatment and surface impregnation used in heat treatment department of the enterprise are:
-
gear bulk hardening up to 269…302 HB, gear diameter is up to 1800 mm;
-
tooth HF current surface hardening up to 42…55 HRC, gear diameter is up to 1400;
-
tooth cementation with subsequent hardening up to 54…62 HRC, gear diameter is up to 800 mm.
Gear grinding equipment of the shop allows to manufacture spur and bevel gearings with 6-7 degree of accuracy.
JSC EZTM gear shop is a regional center which manufactures and repairs spare parts for different types of equipment.
Specialists of the enterprise are ready to assist customers in elaboration of the designing documentation and manufacturing of special reducers as well as in identification and manufacturing of different gearings used as spare parts for imported equipment.
