This is a set of four 6001ZZ shielded wheel bearings for gas and electric scooters. The 6001ZZ wheel bearing is commonly used for 250 watt and 350 watt electric scooters, gas skateboards, and many other applications. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others. Its chrome steel construction makes it durable and resistant to deformity under heavy loads. The metal shields on both sides of the bearing keep lubricant in and contaminants out, and it comes pre-lubricated from the manufacturer so that no additional lubrication is required. This deep-groove shielded ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. The number 6001ZZ is etched on the side of each bearing. Please note that a set of two bearings is required for each wheel. We include four bearings, so you can repair two wheels for a cheaper price.
