GGM K9G Gearhead – 90mm Parallel Shaft Reduction Gearbox for 40W GGM Motors

GGM K9G Gearhead – 90mm Parallel Shaft Reduction Gearbox for 40W GGM Motors

The GGM K9G Gearhead is a series of parallel shaft reduction gearboxes from GGM, specifically designed for 40W GGM motors with a 90mm flange size. This product is used to reduce output speed, increase transmission torque, and ensure stable operation of motor assemblies in compact automation machinery.

The K9G gearhead is compatible with 40W GGM motors using the K9G□B(C) gearhead model, with the K9G10BX decimal gearhead option available for deeper speed reduction. This series is ideal for drive assemblies requiring a compact footprint, direct motor mounting, and ease of replacement during maintenance.

GGM K9G gearheads are commonly applied in mini conveyors, small packaging machines, labeling machines, rotary mechanisms, feeding systems, automated testing equipment, product sorting machines, OEM equipment, and small-capacity drive units. With a wide range of gear ratios, the K9G series allows users to easily select the appropriate output speed for specific operational requirements.

Key Features of GGM K9G Gearhead

The GGM K9G gearhead features a compact, square-box design, perfectly matching GGM motors with a 90mm flange size. The parallel shaft configuration enables direct transmission, making it easy to integrate into machines with limited space while maintaining stable performance.

The K9G series offers various gear ratios, from low ratios such as 1/3, 1/5, 1/10 to high ratios like 1/100, 1/150, 1/180, 1/200. Low gear ratios are suitable for applications requiring higher output speeds, while high gear ratios are ideal for mechanisms needing slower speeds and higher torque.

For deeper speed reduction, users can integrate the K9G10BX decimal gearhead. This is the optimal choice for mechanisms requiring lower output speeds than standard gear ratios provide.

The strengths of the GGM K9G gearhead include ease of model selection, simple replacement, compact design, and suitability for various small-capacity automation applications. This series is particularly well-suited for systems requiring stable transmission, quiet operation, and optimized installation space.

Main Technical Specifications

GGM K9G Gearhead Model List

In addition to the popular gear ratios above, the K9G series also offers intermediate ratios such as 3.6, 6, 7.5, 9, 12.5, 18, 25, 36, 40, 60, 75, 90, providing users with greater flexibility in selecting output speed and torque for specific applications.

Dimensions and Installation Structure

The GGM K9G gearhead uses a 90mm flange, mounting directly to a 40W GGM motor of the same size. The square-box design facilitates easy machine layout, especially in small drive assemblies where space-saving is critical.

Gearhead weight varies by gear ratio group. Higher gear ratio groups typically have larger dimensions and weights, so when replacing, it is essential to verify the correct old model, installation length, and actual space available on the machine.

GGM Motors Compatible with K9G Gearhead

The K9G gearhead is used for 90mm, 40W GGM motors. Compatible motor series include lead wire types, terminal box types, and T5 terminal box types.

Motor information is only used to determine compatibility with the gearhead. When selecting a product, the focus should remain on the K9G series, gear ratio, B/C type, flange size, and actual installation space. For 3-phase motor versions with voltages above 380V, it is not recommended to use them with VFDs as this may affect the motor winding insulation. This is a point to note when selecting a motor-gearhead combination for automation machines.

Applications of GGM K9G Gearhead

The GGM K9G gearhead is suitable for small-capacity drive mechanisms requiring stable output speed, compact size, and easy replacement.

Common applications include:

• Mini conveyors
• Small packaging machines
• Labeling machines
• Feeding machines
• Product inspection machines
• Product sorting machines
• Slow rotary mechanisms
• Light-load push/pull mechanisms
• Compact automation equipment
• OEM machines
• Drive assemblies in production lines

With various gear ratios, the K9G gearhead helps users easily select the appropriate output speed for each machine mechanism. Low gear ratios are suitable for mechanisms requiring faster speeds, while high gear ratios are suitable for mechanisms requiring slow, stable operation and better pulling force.

How to Select the Right GGM K9G Gearhead

When selecting a GGM K9G gearhead, it is necessary to identify the correct model and gear ratio to avoid incorrect output speeds or incompatibility with actual loads.

Information to verify includes:

• Whether the motor in use is the correct 90mm size, 40W capacity
• Whether the required gearhead is K9G...B or K9G...C
• Required gear ratio
• Desired output speed
• Actual load torque
• Installation space on the machine
• Whether the gearhead length fits the installation position
• Whether an additional K9G10BX decimal gearhead is needed

If a high output speed is required, low gear ratios such as 1/3, 1/5, or 1/10 can be chosen. If a slow speed and higher pulling force are required, high gear ratios such as 1/50, 1/100, 1/150, 1/180, or 1/200 can be chosen.

Notes on Replacing GGM K9G Gearheads

When replacing a GGM K9G gearhead, customers should check all information on the old product label. Important information includes the K9G series, gear ratio, B or C symbol, flange size, and the model of the motor attached.

It is necessary to clearly distinguish between models such as K9G10B, K9G20B, K9G50B, K9G100B, K9G200B, as each model has different gear ratios, output speeds, and operating torques.

Choosing the wrong gearhead can result in the motor assembly not fitting, incorrect speeds, lack of pulling force, noise generation, or reduced service life of the drive assembly. For machines currently in operation, it is recommended to take photos of the motor label, gearhead label, and installation position for comparison before replacement.
