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.

Great Pillows for a Good Night’s Sleep
Size: Queen (2 pack), Size: Queen (2 pack)
These pillows are very comfortable and supportive. They keep their shape well and provide great neck and head support throughout the night. The material feels soft and high quality, and they helped improve my sleep. I wake up without neck pain and feel well rested. Definitely worth it.

BEST PILLOW EVER! - But you must follow these instructions
Size: Queen (2 pack)
This is literally the BEST pillow I've ever slept on! It is SO COMFORTABLE, and I can't believe it was $40 for TWO PILLOWS! I slept on a similar, much more expensive name-brand pillow at my friend's house and thought, "I just HAVE to have this pillow!" When I found this one on Amazon for just $20 a pillow, I was so stoked! However, I was turned off by the "paint-like smell" when I slept on it right out of the box the first night. (I was too impatient to try it out!) Do NOT buy this pillow if you're in a hurry, because to get the paint smell to go away, you MUST follow these instructions: 1. Take the pillow out of its case and wash the case. 2. Leave the case off for TWO WEEKS (yes, you heard right!) to let the pillow out-gas. After waiting for two weeks, the smell will be GONE! Yes, I know it's a long time to wait, but it's WORTH IT! As far as the firmness of the pillow is concerned, I took about five big handfuls of the stuffing out and put it in a ZipLoc bag, but my husband liked the pillow as-is. I personally didn't want it so stuffed and wanted a bit "softer" feeling. I also sleep on my stomach sometimes, so taking out five handfuls of stuffing was perfect. I LOVE MY NEW PILLOW! (One thing I wish, however, is that the pillow came in a standard size. My husband and I have queen-size pillow cases, but our kids have standard-size pillow cases. Darn! I want THEM to have a chance to have such a comfy and inexpensive pillow too!)

The cold side really works. It's nice ;)
Size: King (2 Pack)
The soft side aspect of it is really awesome. We like the whole cold pillow thing but personally I feel like it keeps my head too high up so I wake up with a neck pain. But for someone who likes support, this would be a perfect option.

Perfect pillow
Size: Queen (2 pack)
Very comfortable! A light firmness yet you sink into the pillow perfectly. Keeps shape. Fluff right back up instantly when you leave it. Supports and the quality is great for the price.
