Precision ball bearings are designed for extremely improved accuracy for high precision applications such as aerospace, health, robotics, machine tool and other industries. They can include a large variety of bearing types, such as machine tool bearings, ceramic ball bearings
, ball screw support bearings, miniature and instrument bearings, and thin section bearings. Machine tool bearings come in a variety of styles, such as MMX, HX, or MMV, and are designed for high accuracy performance in high-speed applications and strenuous operating conditions. Ceramic or hybrid ball bearings provide an extremely low friction coefficient, accurate high-speed performance, and increased dynamic radial stiffness. Ball screw support bearings are commonly used in motion control applications, and are available in single and double row designs. Miniature and instrument bearings can be radial, angular contact, thrust, or pivot. They are typically used in precise applications such as medical and industrial handpieces, or other small mechanisms. Thin section bearings are used in applications like rotary joints
, gimbals, and robotics. Designs feature radial, angular contact, and fractured race bearings. For additional precision, super precision bearings are available, designed for specific and demanding applications. These bearings feature optimal materials and internal design, to provide the highest quality performance, including accuracy, rotational speed, and rigidity. Other benefits include noise and vibration reduction, high rotational speed, minimized heat generation and friction, and long operating life. Precision ball bearings are available in materials such as bronze and steel. Higher quality bearing materials include ultra clean steel, brass, engineered polymer, and phenolic. As with most bearings, a variety of seal types and lubricant options are available to improve bearing performance. MRO Supply carries a wide selection of precision ball bearings of various manufacturers, styles, materials, and sizes to suit any application.
