The B40-185 is suitable for high-speed, frequent-stop applications of servo motors. Its performance is superior to that of conventional bearings due to improvements in structure, lubrication, and sealing.Here are some advantages of this bearing.
Insulation and anti-electro-erosion: Ceramic beads block shaft current, protecting the servo motor and preventing electro-erosion failure.
High speed and low heat generation: The ceramic has low density and low friction, resulting in a temperature rise of 30%+ lower than that of all-steel bearings at high speeds, and more stable operation.
High rigidity and long life: Silicon nitride ceramics have high hardness and wear resistance, and their lifespan is 2-3 times that of all-steel bearings.
Suitable for harsh working conditions: High temperature resistance, low noise, low friction, suitable for high frequency start-stop and precision positioning scenarios.
Servo motor bearings are manufactured using a variety of high-quality materials, depending on the required precision, operating conditions, and usage scenarios.The inner and outer rings and rolling elements of the bearing are mainly made of high carbon chromium bearing steel. After quenching and tempering heat treatment, the bearing has sufficient hardness, wear resistance, fatigue resistance and good dimensional stability, and can be adapted to servo high frequency start and stop and variable speed operation.For high-speed and high-temperature applications, carburized bearing steel or stainless steel can be selected, which are more tough and resistant to temperature and corrosion.Cages are commonly made of nylon engineering plastics, stamped carbon steel, brass, etc., to suit different working conditions such as quiet operation, high speed, and heavy load. They have low operating resistance and are not easily deformed. The seals are mostly made of aging-resistant, high-elasticity rubber and bakelite materials, and are equipped with special long-life grease suitable for high and low temperature conditions. The overall material combination takes into account precision, wear resistance and stability, which can better meet the long-term operation needs of various precision servo equipment.
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.
