Advanced Spiral Bevel Gear Design for Quiet, Smooth Operation
The TC Series uses precision-machined spiral bevel gear sets to ensure quiet, shock-free transmission. Its advanced geometry enhances contact ratios, leading to higher torque and reduced backlash, making it a superior option compared to conventional bevel gear box designs. This technology is widely trusted by global gear motor manufacturers.

Configurable Inputs and Outputs to Match Any Gearmotor
Compatible with various gearmotor inputs, the TC Series supports 1-in/1-out, 1-in/2-out, 2-in/1-out, and 2-in/2-out designs. Its modular architecture allows for seamless integration into existing setups, whether upgrading a helical gear motor system or engineering a custom industrial drive.

High Torque Density in Compact Dimensions
Despite its small footprint, the TC gearbox supports torque ratings up to 5000 Nm. It’s ideal for applications where space is tight but high power is required—such as conveyor systems, hoisting platforms, or synchronized machinery—especially when used with a high-efficiency helical gear motor or gearmotor.

Built for Demanding Environments
The robust casing, wear-resistant gears, and heat-treated steel components enable the TC Series to perform in extreme industrial environments. As a trusted product from SLM, one of China's top gear motor manufacturers, it guarantees longevity and low maintenance.
