The inner and outer rings of this EPB50-67 are made of high-purity bearing steel, and the quenching and tempering process is well done, resulting in uniform hardness and resistance to deformation.The rolling element is a high-purity silicon nitride ceramic ball. The factory adopts standardized requirements and has a scientific and efficient management process. The ball is free of cracks and pores.The cage material is stable, wear-resistant, and operates without jamming;The seals are reliable in terms of temperature resistance, dustproof and waterproof performance.The external dimensions are 50×130×31mm, the rotation speed is up to 10,000 revolutions per minute, and the outer ring is thickened and has a regular structure.The grease filling amount is suitable for high-speed operating conditions, providing long-lasting lubrication without grease leakage.
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.
We implement standardized management and control over the entire process of servo motor bearings, focusing on the core requirements of batch consistency and stability.From raw material selection and precision machining to heat treatment and ultra-precision machining, each process undergoes rigorous quality inspection to strictly control key dimensional tolerances and raceway precision.Meanwhile, through batch sampling inspection, torque consistency verification, vibration and noise screening, and simulated working condition durability testing, subtle performance differences can be identified, effectively avoiding problems such as batch deviation and uneven individual performance, ensuring that the precision of each batch of bearings is highly consistent and the performance is stable, meeting the high-quality usage requirements of batch assembly into servo motors.
