GGM K8H Series Gearhead: K8H5B, K8H10B, K8H15B, K8H20B, K8H30B, K8H50B, K8H100B, K8H200B

GGM K8H Series Gearhead: K8H5B, K8H10B, K8H15B, K8H20B, K8H30B, K8H50B, K8H100B, K8H200B

The GGM K8H Series gearhead is a reduction gearbox designed for GGM Korea Brushless AC/DC motors, ideal for compact drive systems requiring speed reduction, increased torque, and stable operation in automated machinery. Available models include K8H5B, K8H10B, K8H15B, K8H20B, K8H30B, K8H50B, K8H100B, and K8H200B.

The GGM K8H series is typically paired with motors such as K8BH60N, K8FH60NC, and K8XH50N2, meeting various requirements for output speed, load torque, and installation space. Featuring an 80 mm flange, a Ø15 mm output shaft, and gear ratios ranging from 5 to 200, the GGM K8H gearhead is an excellent choice for small conveyors, packaging machines, labeling machines, rotary mechanisms, automatic turntables, and OEM drive assemblies.

MDriveTech provides genuine GGM K8H gearheads, offering support for legacy model verification, gear ratio selection, compatible motor consultation, and suitable replacement solutions for existing machinery.

GGM K8H Series Gearhead Specifications

GGM K8H Gearhead Dimensions and Mounting Bolts

When replacing a GGM K8H gearhead for existing equipment, verify the gear ratio, shaft diameter, gearhead length, bolt hole positions, and the installed motor model. Incorrect gear ratio selection may lead to incorrect output speed, insufficient torque, or failure to fit the existing assembly.

GGM Motors Compatible with K8H Gearhead

The GGM K8H gearhead can be mounted with the following compatible GGM motor series:

In GGM motor codes, the character U typically indicates 1-phase 100–115V, while C indicates 1-phase 200–230V. Beyond the standard version, motors may include options for brake, encoder, or brake + encoder depending on requirements for stopping, load holding, or speed feedback.

Permissible Torque with AC Brushless Motor

For the K8BH60N + K8H Gearhead combination, the permissible torque is as follows:

For the K8FH60NC motor, when operating in the 100–3000 rpm range, the reference torque values are similar to the table above. If running at 4000 rpm, please check the permissible torque in the catalog to avoid undersizing the load.

Permissible Torque with DC Brushless Motor

For the K8XH50N2 + K8H Gearhead combination, the permissible torque in the 100–2500 rpm range is as follows:

When the DC Brushless motor operates at 3000 rpm, the permissible torque will vary according to the gear ratio. Therefore, when selecting a motor + gearhead set for continuous operation or variable loads, ensure to carefully check the actual operating speed, load torque, and safety factor.

Transmission Efficiency of GGM K8H Gearhead

Transmission efficiency directly affects output torque, operating temperature, and the long-term durability of the drive system. For high gear ratios such as 100 or 200, it is recommended to select the motor and gearhead based on the actual load rather than just the desired speed.

Permissible Shaft Load of GGM K8H Gearhead

Shaft load specifications are critical when the gearhead drives loads via pulleys, sprockets, gears, rotary discs, or mechanisms with lateral forces acting on the shaft. If the overhung load or thrust load exceeds the permissible limits, the bearings and internal gears may wear prematurely, cause noise, or reduce service life.

Applications of GGM K8H Series Gearhead

The GGM K8H gearhead is suitable for small and medium drive assemblies in automation systems, especially in applications requiring low speed, stable torque, and compact installation dimensions.

Common applications:

• Mini conveyors, packaging conveyors

• Labeling machines, date printers, feeding machines

• Packaging machines, filling machines

• Automatic turntables, rotary positioning mechanisms

• Film pulling, paper pulling, and light product pulling assemblies

• Automatic product inspection machines

• OEM equipment in production lines

• Small drive systems using GGM Brushless Motors

With a synchronized design between motor and gearhead, the K8H series enables machine builders to easily select appropriate drive systems, reducing mechanical design time and minimizing errors during component replacement.
