Universal Flange Ball Bearing 4x8x3mm Shielded Chrome Steel Bearings Single-row, pre-lubricated, normal accuracy. Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions. With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance. Chromium Steel (GCr15) made with heat treating, provides high and uniform hardness, good wear resistance, and high contact fatigue performance. Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on.

694ZZ Bearing 4x11x4 Stainless Steel Shielded Miniature Bearings Single row radial ball bearings are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of thrust and radial loads. 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. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others. check out : F604ZZ Flanged Shielded Ball Bearing

2GT 20 teeth pulley wheel for Belt 6mm Perlin passive idler pulley wheel bore 5mm This Aluminum GT2 Timing Idler Pulley wheel For 6mm Belt 20 Tooth 5mm Bore pulley works with GT2 6mm wide timing belt; it will work perfectly with GT2 pulley-belt sets we are selling in our store. This idler is a good match for 20T GT2 driving Timing Belt Pulley. Many DIY 3D printer makers are using idler pulleys based on 3D Printed wheels. Inaccurate printed idler decrease printing quality and create vibrations since the outside diameter of the idler is not concentric to the rotation axis. Other makers are using double bearings with stationary washers clamped from both sides. This solution is not ideal since there is friction between the moving belt to the stationary washers. Our Dual BB Aluminum Idler Pulley is a simple and inexpensive solution to this problem. Check out our entire range of Timing Belt & Pulley .
