Gearhead (3-axis) K&F SB10557 — payload 6 kg, outputs 1/4" and 3/8" for CNC / Arcaswiss

The Gearhead (3-axis) K&F SB10557 is a compact three-axis gearbox designed to convert motor rotation into controlled multi-axis motion for CNC adapters and Arca‑Swiss-compatible mounts. Specified for a payload capacity of 6 kg, this unit features both 1/4" and 3/8" threaded outputs to fit common camera and accessory mounting standards. Its small footprint and geared output make it suitable for precise positioning in camera rigs, small-scale robotic assemblies, and CNC accessories where limited load and standardized screw interfaces are required.

Advantages

The three-axis gearhead provides smooth, repeatable motion transfer with gearing optimized for low backlash and precise adjustment. Inclusion of both 1/4" and 3/8" threaded outputs ensures compatibility with a wide range of tripods, heads, clamps and accessory plates without additional adapters. Its rated 6 kg payload offers a balance between compact size and the ability to manage lightweight camera systems or tooling fixtures in CNC setups. The compact mechanical design simplifies integration into motorized assemblies while keeping alignment and mounting straightforward.

Suitable for

• Motorized camera sliders and compact pan-tilt heads
• CNC accessories requiring small geared axes and standardized mounts
• Arca‑Swiss-style camera plates and clamps integration
• Small robotic joints and prototype automation with limited payload
• Time‑lapse rigs and precision positioning systems for lightweight setups

Key specifications

• Axis configuration: three-axis geared output for multi-axis motion control
• Payload capacity: 6 kg (maximum recommended working load)
• Output fittings: both 1/4" and 3/8" threaded mounts for accessory compatibility
• Form factor: compact gearbox suitable for integration into small assemblies
• Intended use: compatible with CNC and Arca‑Swiss-style mounting systems

How to use

Mount the gearhead securely to the motor or adapter plate according to your assembly layout, ensuring alignment of input and output axes to prevent side loads. Use the appropriate threaded output (1/4" or 3/8") for your camera, plate, or fixture; select the thread that matches the receiving component and tighten to a firm yet controlled torque to avoid damaging threads. For multi-axis setups, confirm each axis is indexed or locked as required before powering any drive motors. Regularly verify mounting integrity and range of motion during initial setup and testing to ensure smooth operation.

Usage recommendations

Use the gearhead within its 6 kg payload guideline and avoid exposing it to excessive lateral loads or impacts. Pair with motors and controllers that provide smooth acceleration and low holding vibration to preserve gear life and positional accuracy. Periodically inspect threaded connections and mechanical interfaces, and apply light lubrication to gears if specified by your integration or maintenance procedures.
