Product Description

B Series Helical Bevel Gear Reducer

Introducing our high-performance B Series Gear Reducer, a robust industrial solution engineered to meet the most demanding power transmission needs. As a flagship offering, the B Series Helical Bevel Gearbox (also known as the Helical Bevel Gear Reducer B Series) combines precision helical and bevel gearing to deliver exceptional efficiency and torque output, making it a top choice for heavy-duty operations.
Designed as a true Industrial Bevel Helical Gear Reducer, our Heavy Duty B Series Gear Reducer is built for continuous operation in harsh environments—from mining equipment and cement production lines to conveyor systems and material handling machinery. The Right Angle Helical Bevel Gearbox configuration offers flexible installation options, adapting seamlessly to space-constrained setups while maintaining optimal power transfer.
 
At its core, the Hardened Tooth Surface Bevel Gearbox design ensures superior wear resistance, low noise, and a longer service life, even under extreme loads. As a High Torque Bevel Gear Reducer, it reliably handles high-load applications with minimal energy loss, ensuring your operations run smoothly and cost-effectively. For customers seeking an all-in-one power unit, our B Series Gear Motor integrates the reducer with a high-efficiency motor, streamlining installation and reducing maintenance overhead. 
Whether you need a standalone B Series Industrial Gearbox or a fully integrated drive system, our B Series Helical Bevel Gear Reducer range delivers the durability, precision, and performance that industrial professionals trust. Engineered to withstand the toughest conditions, it is the ultimate workhorse for your industrial power transmission needs.

Specification

Performance Features:

Performance Features:

Gears are made of high-strength low-carbon alloy steel through carburizing and quenching, with a tooth surface hardness of 54-62 HRC;

The special box design and gear grinding process ensure high precision, excellent tooth contact and low noise;

High transmission efficiency, strong load-bearing capacity and long designed service life.

The square design of the box outer surface increases the heat dissipation area; the auxiliary air-cooled and water-cooled design enhances heat dissipation performance, prolongs the service life of lubricating oil and reduces maintenance costs;

The box body is made of HT250 or Q235-A steel.
