West Coast Drive Style Bearing Block Kit

A West Coast style drivetrain can be finicky to create without precision machining capabilities. This Bearing Block Kit makes it much more accessible for teams to create high performance West Coast Drive style platforms with limited fabrication resources. Simply drill a clearance hole for a shaft to pass through your drive rail, pull your chain or belt tight, and clamp it down with the included hardware. Featuring machined pockets to capture 10-32 Nylock Nuts, these blocks can be used and reused without worrying about damaging threads upon installation. Because each block is the same part, you can keep the screw heads pointing to the outside of your robot for easy maintenance.

This unassembled kit ships with enough hardware to provide significant clamping pressure to help keep your powertrain components tensioned properly, and can withstand upwards of 1500lbs of force along the axis of the tube when properly installed. This means that for most FRC use cases, a team can install these without the need for tensioning devices to keep things aligned.

The AndyMark West Coast Drive Bearing Block Kit is designed to be used with flanged ball bearings with a 1.125 in. outer race, such as our FR8ZZ-HexHD Bearing.

The AndyMark West Coast Drive Bearing Block Kit also includes mounting geometry for components that utilize 2 in. and 1.875 in. bolt circles, such as motors, gearboxes, sprockets, hubs and gears. This makes this product great for many uses outside of your drivetrain, such as a robust interface to make a rotary arm, or an easy-to-use mounting interface for motors to power your mechanisms. The bearing plate is also 2 in. wide, making it perfect to keep two 20DP gears (of which the total teeth add up to 80) meshed together.
