Ultra Precision Motor Shaft

The Ultra precision motor shaft supplied by Guanshuo Factory is not an upgraded version of ordinary motor shafts. Instead, it is an exclusive product that is fully manufactured in accordance with ultra-precision standards, from raw materials, processing to inspection. We adopt full-process CNC automated processing, and each shaft will undergo a comprehensive precision inspection before shipment to ensure that the batch deviation is ≤ 0.001 millimeters. Any non-compliant products will be strictly prevented from being mixed in, ensuring that each batch of products maintains consistent high precision and truly meets the procurement requirements of ultra-precision equipment.

Unlike conventional motor shafts which focus on practicality, this ultra-precise motor shaft emphasizes ultimate precision and extreme environmental adaptability. Whether it comes to dimensional tolerance, surface smoothness, or material toughness and weather resistance, all meet the high-end standards of the industry. It is the core support for high-end ultra-precision equipment transmission and also reflects our core strength as a professional motor shaft supplier.

Product Features

Unmatched precision, zero deviation, more convenient. This is the most core highlight. The key is that the surface tolerance range reaches IT3 to IT4, the diameter tolerance is controlled within ±0.001 to ±0.003 millimeters, the coaxiality is ≤0.002 millimeters, the radial runout is ≤0.003 millimeters, the end face runout is ≤0.002 millimeters, and the outer diameter tolerance reaches h5 standard. After being processed through ultra-precision grinding, mirror polishing and other techniques, the surface roughness of the bearing position is as low as Ra0.05 to Ra0.2, the friction coefficient is close to zero, fully meeting the requirements of ultra-precision gapless transmission and zero-gap assembly. During assembly, there is no need for repeated adjustments, significantly improving the assembly yield.

High-end materials and professional craftsmanship ensure supreme durability. We do not use ordinary substrates. Instead, we specially combine high-end materials such as premium alloy structural steel, bearing steel, and titanium alloy. After undergoing vacuum carbonizing and quenching, deep low-temperature treatment, and ion nitriding and other professional processes, the surface hardness of the shaft body reaches HRC 60 to 65. Meanwhile, the core maintains high toughness. Even under ultra-high-speed and ultra-heavy-load working conditions, it can operate stably, not prone to wear or fracture, significantly extending the service life.

The Ultra precision motor shaft is suitable for use in extreme environments and has extremely low maintenance costs. We offer high-end surface treatments, such as vacuum ion nitriding and ceramic coating treatment, which enable the motor shaft to have extremely strong corrosion resistance and rust prevention properties. Even within the extreme temperature range of -60℃ to 200℃, it can maintain stable performance. Whether it is extreme industrial environments with drastic temperature and humidity changes, strong corrosiveness, or high vacuum levels, it can operate stably for a long time without frequent maintenance, significantly reducing the maintenance costs of ultra-precision equipment.

Our products have stable batches and are suitable for large-scale procurement. The entire process is carried out through numerical control automation processing and comprehensive precision testing, ensuring that the precision of each batch of products remains consistent. The batch deviation is extremely small, fully meeting the standardized requirements for large-scale procurement of ultra-precision motors. During the procurement process, there is no need to worry about assembly problems caused by batch differences, significantly improving the procurement efficiency.
