Slewing drives

TGB Slewing Drives – Power, Precision, and Innovation in Motion

At TGB Group Technologies, we design and manufacture complete slewing drive systems that combine precision engineering with unmatched durability. With more than three decades of experience in motion control technologies - including slewing rings, slew drives, bearings, and gears - TGB has become a global benchmark in the development of rotational motion solutions for industrial, renewable energy, and automation applications.

Headquartered in Barcelona, Spain, and supported by production facilities in China and India as well as a worldwide sales and service network, TGB delivers innovation through engineering excellence. Our Research and Development Department in Barcelona continually advances the design, materials, and efficiency of our drives to meet the most demanding requirements across industries.

What Makes a TGB Slewing Drive Unique

A slewing drive is a complete, enclosed rotary system that provides controlled rotational motion while supporting significant external loads. Unlike traditional open assemblies of gears and bearings, a TGB slewing drive integrates all critical components - slewing ring, worm gear, and sealed housing - into one compact, preassembled, and ready-to-install unit.

This design minimizes installation time, eliminates alignment errors, and ensures consistent performance throughout the product’s lifespan. Each TGB slewing drive is engineered to provide high torque transmission, precise movement, and long-term reliability under extreme working conditions. With their robust sealing systems and optimized lubrication, our drives operate smoothly in dusty, humid, and corrosive environments.

Engineering Excellence and Performance

TGB slewing drives are worm-driven systems, operated by electric, hydraulic, or pneumatic motors. The worm acts as a powerful speed reducer, transmitting torque to the slewing ring at a much lower output speed. This configuration provides two key advantages:

• High torque multiplication, allowing the movement of heavy loads with minimal input power.

• Self-locking capability, which prevents reverse motion and ensures safe, stable positioning without additional brakes or locking mechanisms.

Each drive is tested and certified to meet the highest international quality standards. TGB’s production processes include precision CNC machining, heat treatment, and surface hardening to ensure maximum strength and minimal backlash. Our drives typically operate within a temperature range of –20°C to +70°C and can be configured for horizontal or vertical installations.

Product Range and Customization

At TGB, we understand that every application has unique demands. That’s why we offer one of the most comprehensive slewing drive portfolios in the world, with models suitable for everything from lightweight automation systems to heavy industrial machinery:

• BE Series – Standard industrial version offering high reliability, IP65 protection, and smooth rotation.

• LBE Series – Lightweight aluminum version designed for weight-sensitive applications.

• PRO Series – Reinforced construction with minimal backlash, best sealing performance, and simplified maintenance.

• TE & TGE Series – Designed for high torque and heavy-duty applications; excellent dust and impact resistance.

• TGO Series – Open configuration for applications requiring direct access to gears or components.

• GE & LGE Series – Non-self-locking models for higher rotation speeds and dynamic operations.

• DAD Series – Dual-axis configuration that enables simultaneous azimuth and elevation movement, ideal for solar tracking and antenna systems.

All series are available in multiple sizes, gear ratios, and housing materials, and can be customized with options such as double worm gears, double ball raceways, reinforced flanges, or special surface coatings (C3–C5M or hot-dip galvanized for offshore applications).

Applications Worldwide

Our slewing drives are used across industries and continents in applications where reliability and precision are non-negotiable. They power systems in:

• Renewable energy – single- and dual-axis solar trackers, wind turbine positioning systems.

• Construction and lifting – cranes, aerial platforms, and concrete pumps.

• Industrial automation – conveyors, robotic arms, and assembly lines.

• Agriculture and forestry – harvesters, sprayers, and tree-handling machines.

• Marine and offshore – lifting boats, radar mounts, and offshore cranes.

• Defense and aerospace – antennas, tracking systems, and precision motion equipment.

TGB slewing drives deliver the strength, control, and longevity these demanding fields require.

Installation and Maintenance Excellence

We take responsibility not only for design and production but also for the integration and service life of our products. Each slewing drive is supplied pre-lubricated and tested but must be re-greased before operation to ensure optimal performance. Regular maintenance is simple, as all units feature grease nipples for easy servicing of the worm gear, bearings, and raceways.

We provide detailed installation manuals, specifying bolt tightening sequences, torque values, and re-lubrication intervals. Bolts should be rechecked after 100 working hours and then periodically—typically every three months—to maintain structural integrity. In normal environments, re-greasing is required every 200–400 hours of operation, while harsher environments like marine or desert conditions may demand shorter intervals.

Our focus on easy maintenance and long-term reliability reduces downtime and extends equipment life, giving customers peace of mind and lower operational costs.

Technical Support and Service

TGB offers complete pre-sales and after-sales support to ensure every project’s success:

• Technical consulting and design optimization

• Finite Element Analysis (FEA) and torque calculation assistance
