The Bm5ws Bearingless Motor is a disc valve hydraulic motor engineered without conventional rolling-element bearings, using fluid film support to reduce friction and wear. It operates at a displacement of 48 cm³/rev with a maximum pressure rating of 320 bar and delivers peak torque of 115 Nm at 18 bar. The design eliminates mechanical contact points, reducing maintenance needs and increasing operational uptime.
The rotor and stator are coated with a hardened nickel-tungsten carbide layer, and the fluid film is maintained by precision-machined clearance gaps of 0.01 mm. These features align with standard bearingless motor technology used in automation systems requiring zero-lubrication environments. The housing is aluminum alloy with anodized finish, rated for IP54 ingress protection.
This motor is used in robotic joints, CNC feed drives, and automated assembly lines where cleanliness and low vibration are critical. Buyers include manufacturers in Germany, Japan, and South Korea sourcing components for high-precision machinery. Trade terms are typically FOB Qingdao, with MOQ of one unit and lead times of 20 to 30 days. Packaging is in anti-static foam-lined boxes with humidity indicators.

Before ordering, validate the fluid film clearance, coating composition, and thermal expansion compatibility of the rotor and housing. Request a material test report for the nickel-tungsten carbide layer and confirm the IP54 rating is verified by an accredited lab. Do not accept marketing claims about 'zero maintenance' without technical proof.
Lead time is typically 20 to 30 days, but confirm with the supplier. Trade terms are commonly FOB Qingdao, with payment via T/T 30% deposit and 70% before shipment. Ask whether the motor is tested under load before packing and if a test certificate is included. Clarify if Incoterms include insurance and unloading at destination.
Upon receipt, inspect for surface scratches on the rotor, evidence of moisture in packaging, or deformation of the housing. Conduct a no-load pressure test to verify smooth rotation and absence of vibration. Retain all packaging for potential return. Ensure the supplier provides a packing list with serial numbers and a declaration of conformity for the coating material, even if no ISO certification is available.
