Upgrade your drivetrain or mechanism in mobile robotics, mobile automation, or FIRST Robotics Competition (FRC) builds with this 20 DP aluminum spur gear from WestCoast Products—offered via CTR Electronics. Engineered for performance, this gear fits ½″ hex shafts and offers consistent dimensions for flexible design and ratio changes.

Key Features & Specifications:

• Diametral Pitch: 20 DP with 14.5° pressure angle (industry standard for many FRC gearbox systems)
• Bore: ½″ hex bore, compatible with hex or ThunderHex shafts
• Material: 7075-T6 aluminum with a Teflon-infused ceramic coating for wear resistance
• Face Width / Overall Width: Uniform width (0.500″) across all gear variants, enabling interchangeable gear stages without changing housing width 
• Clocked Hex Bore: All laser-engraved gears are clocked (i.e. rotational orientation is fixed), ensuring alignment consistency in gear meshes 

Benefits for Robotics, FRC & Automation Use:

• Interchangeable Ratios: Because all sizes share the same width and pressure angle, you can swap in different tooth-count gears easily in your robot’s gearbox or mechanism without redesigning mounts or spacing.
• Lightweight & Strong: 7075-T6 aluminum gives a strong yet lightweight option, ideal for mobile robotics where weight is critical.
• Smooth Meshing: The consistent 20 DP spec ensures compatibility with common FRC spur gear sets and allows precise tooth engagement, reducing noise, backlash, and wear in drivetrain and actuator systems.
• Mobile Automation Ready: Whether your system is an autonomous mobile robot, automated guided vehicle, or robotic motion module, this gear is well-suited for compact gearboxes in mobile automation and mobile robotics platforms.
• FRC Proven Design: Geared for use in FIRST Robotics Competition drivetrains and mechanism gearboxes, this spur gear meets the expectations of FRC teams looking for modular, robust drivetrain components.

Note: Hex bore is clocked on all laser engraved gears.
