RPI SHOP - 607Zz (7mm X 19mm X 6mm) Double Shielded Miniature Ball Bearing, For 3D Printers, Robotics, DIY Projects Pack of 4 Pcs Wheel Bearing

★ Product Description: ◆ Shielded Miniature Ball Bearings has deep groove geometry for high speeds and supporting both radial and axial 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." ★ Uses: ◆ Widely used in: Roller skates, Skateboarding, Twisting cars, Running shoes, In-line wheels, Double row wheels, MTB, SUV, and other Extreme sports equipment. ◆ Fit for skateboards, inline skates, roller skates, scooters, and other skating applications, also available for 3D printer wheel bearings, CNC, EMAX, cooling fan, etc. ◆ Also used in industrial engineerings, such as Machinery, Power Transmission, Instrumentation, Household appliances, Internal combustion engines, Transport vehicles, Agricultural machinery, Construction machinery.
