We support special, non-standard, and application-specific motor spindle customization according to machine structure, working conditions, installation dimensions, speed requirements, and customer drawings or technical specifications.
Supported by ISO 9001 quality management certification, CE certification, patents, and trademark registration, we maintain strict quality control and compliance standards throughout motor spindle manufacturing.
We provide fast response, warranty support, and professional technical assistance to help customers reduce downtime, maintenance costs, and operational risks after delivery.
BKZ Industry is a motor and electric spindle manufacturer based in Jiangsu, China. Our factory covers more than 20,000 square meters and is equipped with advanced processing and inspection equipment to support stable manufacturing, precise testing, and reliable product quality.
Yes. Motor spindle and electric spindle usually refer to the same product: a spindle unit with a built-in motor that directly drives the spindle shaft. “Motor spindle” is more commonly used in international technical and CNC machining contexts, while “electric spindle” is also widely used by many Chinese manufacturers as a direct translation.
A motor spindle usually includes a spindle shaft, built-in motor, rotor, stator, precision bearings, housing, tool interface, clamping system, cooling system, lubrication system, sealing system, sensors, electrical connectors, and mounting structure. These components work together to provide high-speed rotation, tool holding, positioning accuracy, cooling, lubrication, and stable machining
A belt-driven spindle is driven by an external motor through belts and pulleys. The motor is installed outside the spindle unit, and power is transmitted to the spindle shaft by the belt system.
A motor spindle has the motor built directly into the spindle body. The rotor and stator drive the spindle shaft directly without belts or pulleys, allowing a more compact structure, faster speed response, lower transmission vibration, and better suitability for high-speed CNC machining.
Electric spindles offer high speed, compact structure, direct drive transmission, faster acceleration, lower vibration, better running accuracy, and higher machining efficiency. Because there is no belt transmission, they reduce mechanical transmission loss and are suitable for high-speed milling, drilling, tapping, engraving, grinding, and precision CNC machining.
When buying a motor spindle, you should provide the spindle type, power, rated speed, maximum speed, voltage, frequency, tool interface, cooling method, lubrication method, bearing configuration, mounting dimensions, application, machining material, and working conditions. If you have drawings, machine model, or replacement spindle specifications, sending them will help the supplier recommend the correct model faster.
In our motor spindles, we use H7005C-2RZ HQ1 DT P4 angular contact ball bearings. This bearing has a 25 mm bore diameter, 47 mm outside diameter, and 12 mm width. It has a 15° contact angle, non-contact seals on both sides, tandem arrangement, and P4 precision grade, making it suitable for high-speed and high-precision spindle operation.
Yes. We support ordering one sample motor spindle before bulk purchasing. You can contact BKZ Industry with your spindle specifications, application requirements, drawings, or replacement model, and our team will help confirm the suitable motor spindle solution.
Our motor spindles are widely used in CNC machine tools, robotic automation equipment, ceramic ferrule processing, special motor applications, precision engraving, grinding, drilling, tapping, high-gloss machining, turn-mill machining centers, and other high-speed machining fields.
In addition to motor spindles, BKZ Industry also supplies bearings, bearing housings, gear couplings, and other transmission components for industrial equipment. These products are used in CNC machines, automation systems, machine tools, motors, gearboxes, and other mechanical systems.
Tell us your machine type, spindle model, application, power, speed, tool interface, cooling method, installation dimensions, and quantity. Our team will review your requirements and provide a suitable motor spindle quote.
