A pair of final drive gears (main pair) is designed to transmit torque directly to the drive wheels.
The main pair is designed for vehicles of UAZ 452,469,3151 models equipped with Timken (aka Kolkhozny) and Hybrid axles.
Quality and reliability are the main criteria that we pay attention to.
The production technology involves the gradual processing of the surface layer of the main pair - so the gear teeth acquire optimal physical characteristics.
Nitrocarburizing of the teeth gives the metal layer increased wear and corrosion resistance, while maintaining the internal plasticity of the metal structure: it is important under extreme loads on the transmission during operation.
Surface hardening of the teeth increases the strength characteristics of the product to 57-63 HRC on the Rockwell scale.
Phosphate-molybdenum coating of the teeth eliminates deformation and minimizes noise during the rolling of gears.
