P4 Precision Double-sided Sealed Servo Motor Bearing F-568241

The materials used in different parts of a servo motor bearing vary. We will introduce the materials of each part of the servo motor bearing by component. For the raceway and rolling elements, high carbon chromium steel is generally used. Most bearings use SUJ2 steel, a JIS standard, while large bearings use SUJ3.For applications requiring impact resistance, chromium steel, chromium-molybdenum steel, or nickel-chromium-molybdenum steel can be used, with carburizing and quenching treatment.In addition, there are special materials such as stainless steel, ceramic materials and high-speed steel.The cage is made of materials such as cold-rolled steel, brass plate, stainless steel plate, carbon steel, and synthetic resin.It should be noted that polyamide cages should not be used in environments with temperatures above 120 degrees Celsius or below -40 degrees Celsius, nor are they suitable for vacuum environments.Brass cages should not be used in environments with temperatures exceeding 300 degrees Celsius or in ammonia environments. The most commonly used bearing steel material on the market is GCR15.We have introduced several commonly used materials for servo motor bearings, but the selection of materials should be determined based on the specific application scenario and performance requirements.

Servo motor bearings, with their graded precision specifications, are suitable for a variety of industrial applications. For conventional automated equipment such as packaging machinery and ordinary conveyor production lines, basic precision bearings can be selected to ensure stable operation while reasonably controlling costs. Equipment such as CNC machine tools, 3D printers, and industrial robots have higher requirements for motion precision and response speed, so they are equipped with precision bearings to ensure accurate movements and smooth operation. In ultra-precision fields such as semiconductor equipment and high-end optical inspection instruments, top-precision bearings are selected to easily meet the stringent control requirements at the micron level

Bearings are prone to problems such as accelerated wear, grease aging, and decreased precision after long-term use, making them unsuitable for the continuous operation of servo equipment under long-term, high-load conditions. The servo motor bearings, through precision process optimization, material upgrades, and exclusive lubrication matching, possess excellent long-term stability. They can resist the wear caused by alternating loads, temperature changes, and high-speed friction for a long time, and can maintain precise rotation accuracy and stable operation. This effectively delays performance degradation and ensures long-term high-precision, low-failure, and stable operation of servo equipment.
