Key Advantages

Drop-in Interchangeability: Built to standardized international mounting dimensions, offering seamless, cost-effective replacement for mainstream European brands.

Right-Angle Space Efficiency: The 90° bevel output minimizes long linear footprints, allowing close-coupled installation along machine walls and conveyors.

Integrated Drive Reliability: Pre-engineered motor-gearbox coupling eliminates alignment errors, reducing vibration and installation labor on machine floors.

High-Precision Power Transmission: Premium case-hardened steel gears milled to ISO/DIN Grade 5–6 yield mechanical energy efficiencies up to 95% per stage with minimal heat generation.

Rugged Mechanical Options: Supports both foot/flange mountings and solid/hollow output shaft configurations for high adaptability across diverse drive designs.

Industrial Applications

Conveyor Systems: Continuous duty drives for heavy bulk material, roller, chain, and belt conveyors in logistics and mining.

Bucket Elevators & Hoists: High-torque, right-angle lifting drives requiring backstops or brake configurations for secure vertical handling.

Agitators & Industrial Mixers: High axial load capability suited for chemical, food processing, and wastewater treatment mixing tanks.

Material Handling & Cranes: Smooth travel drives for gantry cranes, automated transfer cars, and port machinery.

Packaging & Processing Lines: Precision gear ratios support synchronized automation in bottling, timber, and pharmaceutical equipment.

Gearbox Construction

The GK Series utilizes a balanced housing architecture integrating high-grade materials and precision components:

Helical Gear Stage

High-tensile alloy steel (20CrMnTi) gears, carburized and ground to ISO Grade 5–6, providing primary speed reduction and torque transfer.

Bevel Gear Stage

Precision spiral bevel gears change transmission direction by 90° while smoothly handling multi-directional loads.

Robust Housing

High-rigidity HT250 cast iron casing designed with finite element analysis (FEA) to absorb vibration and maintain internal alignment.

Heavy-Duty Bearings & Seals

Premium brand tapered roller bearings absorb high radial and axial thrust loads; dual-lip FKM oil seals protect against leakage and ingress.

Optimized Lubrication

Built-in splash lubrication with strategic breather and drain plugs tailored to specific mounting orientations.

Mounting & Output Shaft Configurations

Flange Mounted Bevel Helical Geared Motor

To accommodate varied machine designs, the GK Series offers multiple structural configurations:

Foot Mounting (GK): Rigid bottom-mounting feet for secure bolting to machine foundations.

Flange Mounting (GKF/GKAF): Precision B5 or B14 flanges for direct face-mounting to driven equipment.

Solid Output Shaft: Fitted with keyways for coupling, chain sprocket, or belt pulley attachments.

Hollow Output Shaft (GKA/GKAF): Keyed, splined, or shrink-disc clamping for space-saving, direct-drive shaft insertion.

Torque Arm Support: Rubber-buffered torque arm absorbs reaction forces in shaft-mounted arrangements.
