The AndyMark 4in. Performance Wheel XL 0.5in. Hex Bore is a robust and durable wheel crafted from solid 6061 aluminum, renowned for its resilience in competitive robotics environments. This wheel has been a staple in the FIRST Robotics Competition, offering a proven design that withstands the rigors of intense robotic activities. The latest iteration of this wheel is 50% wider than its predecessors, enhancing traction significantly.
Engineered to be driven by a 0.5-inch hex shaft, the wheel is compatible with various motion hardware that utilizes a 1.875-inch 6-hole bolt circle, a common feature in AndyMark and other competitive robotics products. The design includes a 1/8-inch thick boss on the rear side to minimize friction in bearing outer races, thereby reducing the number of components required in drivetrains.
The wheel is intended to serve as a blank canvas for customization, with no pre-drilled holes on the rim, allowing teams to install rivets as needed. It is recommended to use steel rivets with specific dimensions for optimal performance. This wheel does not come with tread material, providing flexibility for teams to choose their preferred tread. Note: Ensure the use of appropriate rivets to securely attach the tread to the wheel.
