10 bearings 604ZZ 4x12 covered 4x12x4 Description

① Deep groove geometry for high speeds and for accommodating radial and axial loads. ② Chrome steel for durability and resistance to deformation under high loads. ③ Metal shields on both sides of the bearing to retain lubricant and keep out contaminants. ④ Pre-lubricated by the manufacturer, so no additional lubrication is required. ⑤ This 4x12x4 mm covered miniature ball bearing 604ZZ features a deep groove geometry for high speeds and for accommodating radial and axial loads. Its chrome steel construction makes it durable and resistant to deformation under high loads. ⑥ Material: Bearing steel. ⑦ Color: Silver. ⑧ The metal shields on both sides of the bearing retain lubricant and keep out contaminants, and it comes pre-lubricated by the manufacturer, so no additional lubrication is required. ⑨This covered miniature deep groove ball bearing is suitable for applications subject to combined radial and axial loads and requiring high running accuracy at high rotational speeds. ⑩Such applications include, but are not limited to, couplings, drives, gearboxes, compressors, pumps, turbines, and printing and textile machinery. ⑪Rolling bearings use rolling elements to maintain separation between moving parts to reduce rotational friction and accommodate radial and axial loads. ⑫Sealed bearings are lubricated with oil or grease at the bearing factory, while open and covered bearings are designed for lubrication at the point of use, with periodic relubrication depending on the application. ⑬The shield protects the working components of the bearing from environmental particles that could penetrate and affect the speed and service life of the ball bearing. ⑭Rolling bearings are used in a wide variety of applications, including agricultural machinery, conveyors, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and rock crushers. ⑮Package contents: 10 x deep hole ball bearings ⑯Note: Light shooting and different displays may cause the actual product color to differ slightly from the actual product.
