Extendable Linear Rack Gear Mod 1.6 50-Tooth with Joining Mechanism for Unlimited Length

Quick Introduction: Break the limits of travel distance with the Extendable Linear Rack Gear. While standard racks restrict your movement to their cut length, this 22.6 cm with Mod 1.6 rack features a smart joining mechanism that allows you to snap or screw multiple units together end-to-end. Whether you are building a 2-meter-tall elevator mechanism or a long-span sliding camera rig, this 50-tooth rack grows with your project.

Detailed Specifications

• Module (Pitch): Mod 1.6.

• Length: 22.6CM per segment.

• Teeth Count: 50 Teeth per segment.

• Material: High-Quality Industrial Plastic (Yellow/Nylon).

• Extension Feature: Integrated interlocking ends (Extension Provision) for seamless joining.

• Mounting: Multiple mounting holes along the body for secure chassis attachment.

• Gear Type: Straight Spur Rack.

Quality Advantage & Differentiation: Why choose this Extendable Rack?

1. Unlimited Travel: The specialised extension provision allows you to chain multiple racks together without pitch errors at the joint, enabling travel distances of 1 meter, 2 meters, or more.

2. Mod 1.6 Strength: Built with the robust Mod 1.6 profile, the teeth are thick enough to handle significant torque applications like window openers or heavy sliding doors, unlike fragile Mod 1.0 gears.

3. Modular Design: Buy exactly what you need. If your machine expands, just add another rack segment instead of replacing the entire rail.

Key Applications & Usage

• Long-Span Sliders: Camera dollies or linear tracks that need to span several feet.

• CNC & Plotters: X or Y-axis movement for large-format drawing machines.

• Vertical Lifts: Multi-stage elevators or dumbwaiter prototypes requiring long vertical travel.

• Automatic Doors: Sliding mechanisms for pet doors or windows.

What's Included & Required

• Included: 1x Extendable Linear Rack Gear (50T).

• Required: Compatible Mod 1.6 Pinion Gear (Sold separately). To extend, simply purchase multiple units.

The "Virtual Technician" Support Panel

• ⚠️ JOINING INSTRUCTIONS:

  • Mechanism: The ends of the rack are shaped (dovetail or step-lock) to mate perfectly with the next rack.

  • Alignment: When joining two racks, place them on a flat surface. Use an old Mod 1.6 gear (or the pinion you plan to use) to bridge the gap and check that the teeth mesh smoothly across the joint before tightening the mounting screws. This ensures there is no "bump" when the motor passes the seam.

• ⚠️ COMPATIBILITY CHECK:

  • Ensure you are using Mod 1.6 Pinions. Standard hobby servo gears (often Mod 0.5) or small DC motor gears (Mod 0.8/1.0) will NOT fit.

• ⚠️ MOUNTING:

  • The joining mechanism aligns the teeth, but the structural strength comes from mounting both racks firmly to a rigid backing beam (wood, metal, or extrusion). Do not rely on the plastic joint alone to hold the weight.
