Dimensionsouter diameter: 40 - Inner diameter: 17 - Model: UC203 - Outer height: 14mm - Inner height: 27.4mm - Accuracy class: P1 High quality Bearings are made of steel for durability and resistance to rust, corrosion and warping under heavy loads. FeaturesBall bearings use rolling elements to hold separation between moving parts to reduce rotational friction and bear radial and axial loads, and it has small friction and high limit speed. Strictly shieldedThe bearing has a shield to keep lubricant and contaminants out; protects the working parts of the bearing from environmental debris that may be introduced and could reduce the speed and life of the ball bearing. ApplicationBall bearings are used in a range of applications. applications, from agricultural machinery to transport equipment, robotics, dental equipment, elevators, roller mills, boat rudder shafts, aggregate crushers, skateboards, rollerblades and scooters, among others. Product Description Deep Groove Bearings Description: Deep Groove Bearing is a single row bearing to support radial loads. Bearings are made of bearing steel for durability and resistance to rust, corrosion and warping under heavy loads, and are double-sided shields to keep lubricant in and contaminants out. outdoors, and they are used in a range of applications from agricultural machinery to transportation equipment, robotics, dental equipment, elevators, roller mills, boat rudder shafts, skateboard rudder aggregate grinders, etc. /p> Specifications: Outer diameter: 40 mm.
