The CIM Sport is a competition tested high performance line of planetary gearboxes from AndyMark and BaneBots. The CIM Sport features numerous improvements over previous planetary gearboxes used on FIRST Robotics Competition robots.
The cold formed steel gears inside this gearbox are a 0.7 Module tooth profile which is 40% larger than the vast majority of planetary gearbox gears previously used on competition robots. The gears are larger, but the housing's size has been optimized to reduce any unnecessary volume. This means you get more reliability without sacrificing precious space. This housing is also one solid piece of aluminium, ensuring that there is no possibility for misalignment of the stages during assembly or during the rigors of match play. Three stage, and now optionally two stage, versions of these gearboxes also feature an "HD" stage, with gears approximately double the face width of the other stages as well as a strengthened carrier plate. These larger gears on the output stage ensure that it will handle heavy or cantilevered loads without worry. The carrier plates are made of hardened 4140 steel and interface to the output shaft with a robust hex bore. New for 2019 we are opening up the use of every available gear ratio with every available motor input meaning there are some combinations that could theoretically exceed the gearboxes design characteristics. As such the blanket warranty we offered on these gearboxes in the past will be discontinued for future purchases. Rest assured that AndyMark still stands behind our product 100% and if you feel that there is a problem with your gearbox or any of our products please contact us and we will make it right. To help you decide which gearboxes to use for your application please reference the below table which includes the maximum torque that the gearbox is designed to take before it will fail. A free packet of red tacky grease (am-2768) is included with every gearbox purchased. This grease must be used to coat every internal surface of the gearbox before use. The CIM Sport includes mounting hardware for any CIM style motor including the CIM, the MiniCIM, or the NEO. To install one of these motors, first remove any installed pinion from the motor and press on the included pinion gear using an arbor press or bench vice. This press fit ensures a solid mechanical connection between the pinion gear and the motor. This pinion assembly is not susceptible to vibration and never needs to be checked once installed. All ratios of Blue Sport Gearboxes use a 4:1 input stage, with the same tooth count pinion, so motors and gearboxes can be switched out with ease. The CIM Sport can be used with the optional alternative short back block (am-3769). This can be used to shorten any ratio of the gearbox by 0.92 in. and lighten it by 0.23lb. To use this back block the CIM output shaft must be cut down by 0.92 in. and the pinion pressed onto this shortened shaft. For detailed instructions please see the Motor Installation Guide under the downloads tab.
Common Physical Specifications:
This is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load. This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.

You asked, we listened! These 3" diameter HD (heavy-duty) solid-core Compliant Wheels are intended for manipulating objects where you need a little 'give' in your intake system. These wheels deform out of the way to allow rigid objects to be manipulated easily. This makes for high-performance intakes and internal conveyors. These wheels do not require the use of expensive hubs to be driven, thanks to their integrated high strength polycarbonate hubs - which are made from the same mold that creates our Hex Molded Spacers.
Different durometer ratings give each wheel unique characteristics. Green compliant wheels (35A durometer) are the softest and most compliant around objects, while maroon (45A) blue (50A) and black (60A) wheels are increasingly firm.

Product Overview:
The Sushi Roller Intake Wheels are an excellent choice for robot intakes, internal conveyors, feeder mechanisms, or anywhere you need a durable, compact and grippy roller. These rollers are made with a robust polycarbonate hex bore hub, so no external hub is necessary - just slide them onto a hex shaft, constrain them axially and you are good to go. Available in a range of durometers for a wide variety of applications, these cute little rollers are great for getting a grip on things!
A staple in any robotics team's shop - the 1/2" rounded hex shaft. This shaft allows you to drive hubs, pulleys and other 1/2" hex broached items while also fitting into a 13.75mm ID bearing with ease. This shaft comes in lengths of 36 inches so you can cut them down to the size you need.
Available in both 7075 (anodized black) or 6061 (not anodized) variants.
Includes a hole sized for #10 taps.
8 different offerings of our 25 Series Plate Sprockets. These are perfect for meshing with roller chain and finally getting that-thing-that-you-need-to-spin moving!
These aluminum sprockets work perfectly with any of our 6 hole hubs and mesh with #25 roller chain. They also work with other build systems that use a 2 in. bolt circle for mounting. The larger versions also have a mounting pattern compatible with 2x1 box tube usefull for making arms.
This is the 42 tooth pulley used in the AM14U family of chassis. It works with all 5 mm pitch HTD timing belts. This pulley has a 1.875 in. bolt circle making it easy to attach to many of our motion components. It also has a locking pattern that is compatible with many of our wheels. This pulley comes as two identical halves that mesh with each other to create one pulley that is the correct width for a 15 mm timing belt. Need to have two 15 mm belts on one pulley? Add in the 15 mm wide, 42 Tooth Pulley Extension (am-2813) and you can run two belts in two different directions.
This shaft is an optional part that be used in the 57 Sport Gearbox, as well as the CIM Sport Gearbox. If your application requires a longer output shaft you can disassemble the 57 Sport or CIM Sport and swap for this shaft.
