The outer tread is TPU (Thermoplastic PolyUrethane). This robust but lightweight wheel provides good traction on carpet and soft tiles. Stealth wheels are the perfect drive wheel for smaller (\u0026lt;50 lb.) robots, and both Stealth and Sushi rollers are great for intakes and other auxiliary robot mechanisms. These wheels are available in a variety of bores and durometers. 3 in. and 4 in. Stealth Wheels feature a 6 bolt pattern on a 1.875 in. bolt circle for mounting sprockets, hubs, and gears. \u003ca href=\"\/pages\/resources-am-academy-what-is-the-bore\"\u003eNub Bore\u003c\/a\u003e Stealth Wheels feature a 4 bolt pattern on a 16 mm bolt circle found in most FIRST Tech Challenge building systems.

The \"right\" and \"left\" refer to the direction the rollers are pointing when viewing the wheel as if your about to get run over by the wheel itself.  If the roller in the middle of the wheel points up and to the right, it's a \"right\" wheel, and up and to the left would be a \"left\" wheel. \u003cbr\u003e\u003cbr\u003e The configuration of these \"right\" and \"left\" wheels is important to a mecanum drive system! Be aware that the \"right\" wheel should not mean that it goes on the right side of your robot. The proper configuration would be to have the wheels create an \"X\" pattern when viewing your robot from above and drawing lines parallel to the rollers as viewed.\u003cbr\u003e This means that a \"right\" wheel would be the FRONT RIGHT, and the REAR LEFT position, while the \"left\" wheel would be in the FRONT LEFT, and REAR RIGHT, of your robot when viewed from above. All 4 wheels are required to make a Mecanum drive holonomic system to work properly.\u003cbr\u003e Using these for an intake? This has been a great use of these wheels as well! The angle of these wheels help drive the object in one direction, so you can pull in the object at the same time as pushing at an angle from the intake.\u003cbr\u003e This version of the wheel can handle a 200 pound load per wheel for a total 800 pound load if using as drive wheels! The interior body of this wheel is made of molded black polycarbonate, while the perimeter side plate is made of 1\/8 inch thick steel, zinc plated. The perimeter plate is riveted to the interior body, and each perimeter bent tab rests on the interior body rim. This support allows for the wheel to handle more load. \u003ch3\u003eWheel Bores:\u003c\/h3\u003e\n \u003cul\u003e \u003cli\u003eBearing Bore \t\u003cul\u003e \t\u003cli\u003ethe Original 4 in.

This wheel was optimized for an FTC Chassis, such as the \u003ca href=\"\/products\/mecanam-ftc-chassis?sku=BTMMB2N\"\u003eMecanAM Chassis\u003c\/a\u003e. These wheels ship as an unassembled kit.\u003cbr\u003e A full set consists of 2 \"right\" wheels and 2 \"left\" wheels. The \"right\" and \"left\" refer to the direction the rollers are pointing when viewing the wheel as if you're about to get run over by the wheel itself.  If the roller in the middle of the wheel points up and to the right, it's a \"right\" wheel, and up and to the left would be a \"left\" wheel.\u003cbr\u003e \u003cbr\u003eThe configuration of these \"right\" and \"left\" wheels is important to a mecanum drive system! Be aware that the \"right\" wheel should not mean that it goes on the right side of your robot. The proper configuration would be to have the wheels create an \"X\" pattern when viewing your robot from above and drawing lines parallel to the rollers as viewed.\u003c\/div\u003e\n\u003cdiv\u003e\nThis means that a \"right\" wheel would be the FRONT RIGHT, and the REAR LEFT position, while the \"left\" wheel would be in the FRONT LEFT, and REAR RIGHT, of your robot when viewed from above.

The \"right\" and \"left\" refer to the direction the rollers are pointing when viewing the across it's rolling axis.  If the roller in the middle of the wheel points up and to the right, it's a \"right\" wheel, and up and to the left would be a \"left\" wheel.\u003cbr\u003e \u003cbr\u003eIf using these as a drive wheel for a small robot platform, the configuration of these \"right\" and \"left\" wheels is important. Be aware that the \"right\" wheel does not mean that it goes on the right side of your robot. The proper configuration would be to have the wheels create an \"X\" pattern when viewing your robot from above and drawing lines parallel to the rollers as viewed. This means that a \"right\" wheel would be the FRONT RIGHT, and the REAR LEFT position, while the \"left\" wheel would be in the FRONT LEFT, and REAR RIGHT, of your robot when viewed from above.

This wheel's features are a culmination of our hard work in developing the Mecanum wheel since we introduced an affordable wheel to the market in 2006. This version was previously updated in the fall of 2017, and is an improvement on our previous HD (Heavy Duty) version. It has the same heavy duty features, but with an added smoothness while rolling. We minimized the gaps between the rollers, enabling this wheel to be our \"smooth rolling\" (SR) Mecanum Wheel. \u003cbr\u003e\u003cbr\u003e For 2020 and beyond, we've removed the rivets that hold the Form Plates to the Mid Form dishes, and have begun utilizing 10-32 screws and standoffs to hold each wheel 'half' together.

For these applications, a higher rpm shows that the wheel may wobble, since the valve stem is mounted off to one side of the center of the wheel hub. We have seen properly balanced wheels, using securely mounted hardware (longer screws, washers) that can handle 5,000 rpm. When spinning this wheel at speeds up to 5,000 rpm, please take proper safety precautions. \u003ch3\u003eIncluded Items:\u003c\/h3\u003e\n \u003cul\u003e\n\u003cli\u003eTire for 6 Inch Pneumatic Wheel (Metric Size 150x50mm), \u003ca href=\"\/am-2474\"\u003eam-2474\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eInner Tube for 6 Inch Pneumatic Wheel, with 45 Degree Stem (for 150x50mm Tire), \u003ca href=\"\/am-2475\"\u003eam-2475\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eHub Assembly for 6 inch Pneumatic Wheel, which includes two (2) black plastic hub halves and six (6) 4-40 x1 Pan Head Phillips thread rolling screws\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch4\u003eNOT Included Hardware:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBearings\u003c\/li\u003e\n\u003cli\u003e#10 Screws and Nuts Needed to Mount a Hub (2 Inch Long Screws are Needed) or a Sprocket (2.25 Inch Long Screws are Needed)\u003c\/li\u003e\n\u003cli\u003eAluminum Hub, if driven by a shaft\u003c\/li\u003e\n\u003c\/ul\u003e ---------------------------------------------------------------------------------------------------- \u003ch4\u003eWheel Structure:\u003c\/h4\u003e\n The hub halves are held together with the #4-40 screws.

For these applications, a higher rpm shows that the wheel may wobble, since the valve stem is mounted off to one side of the center of the wheel hub. We have seen properly balanced wheels, using securely mounted hardware (longer screws, washers) that can handle 5,000 rpm. When spinning this wheel at speeds up to 5,000 rpm, please take proper safety precautions. \u003ch3\u003eIncluded Items:\u003c\/h3\u003e\n \u003cul\u003e \t\u003cli\u003e\n\u003ca href=\"\/product-p\/am-0972.htm\"\u003eTire for 8 Inch Pneumatic Wheel\u003c\/a\u003e (Metric Size 200x50mm)\u003c\/li\u003e \t\u003cli\u003e\n\u003ca href=\"\/product-p\/am-0973.htm\"\u003eInner Tube for 8 Inch Pneumatic Wheel, with 90 Degree Stem\u003c\/a\u003e (for 200x50mm Tire)\u003c\/li\u003e \t\u003cli\u003e\n\u003ca href=\"\/product-p\/am-0971.htm\"\u003eHub Assembly for 8 inch Pneumatic Wheel\u003c\/a\u003e, which includes two (2) black plastic hub halves and six (6) 4-40 x1 Pan Head Phillips thread rolling screws\u003c\/li\u003e \u003c\/ul\u003e \u003ch4\u003eNOT Included Hardware:\u003c\/h4\u003e\n \u003cul\u003e \t\u003cli\u003e\n\u003ca href=\"\/Bearings-s\/239.htm\"\u003eBearings\u003c\/a\u003e\n\u003c\/li\u003e \t\u003cli\u003e#10 Screws and Nuts Needed to Mount a Hub (2 Inch Long Screws are Needed) or a Sprocket (2.25 Inch Long Screws are Needed)\u003c\/li\u003e \t\u003cli\u003eAluminum Hub, if Driven by a Shaft\u003c\/li\u003e \u003c\/ul\u003e ---------------------------------------------------------------------------------------------------- \u003ch4\u003eWheel Structure:\u003c\/h4\u003e\n The hub halves are held together with the #4-40 screws.
