Applications
1. Compact High-Speed CNC Drilling & Milling Spindles Exclusively applied to small and lightweight high-frequency spindles for 3C precision processing, PCB micro-drilling and miniature mold engraving equipment. Its ultra-thin wall structure perfectly fits narrow spindle installation space that regular-size bearings cannot adapt to. With P5 precision and 15° contact angle, it balances high-speed operation and slight radial-axial composite loads, ensuring stable micro-hole machining accuracy and smooth surface finish for delicate electronic parts.
2. Miniature Industrial High-Speed Rotary Motors Specially matched for high-speed rotating shafts of compact servo motors and precision drive motors in automated production lines. Different from heavy-duty bearings, this model's low-inertia phenolic cage effectively reduces operating heat and vibration, supporting long-duration continuous high-speed operation of small power motors and guaranteeing consistent transmission precision.
3. Precision Testing & Laboratory Analytical Equipment Serves as the core support bearing for high-speed rotary components of laboratory centrifugal separators, spectral detection instruments and microscopic scanning devices. Its strictly controlled P5 dimensional tolerance minimizes rotary runout and mechanical jitter, avoiding detection data deviation and meeting the high stability requirements of precision experimental testing.
4. Light-Duty Precision Textile & Packaging Machinery Exclusive for high-speed rotary moving parts of intelligent textile looms, automatic quilting machines and high-speed packaging equipment. It adapts to frequent start-stop and continuous cyclic operation, with low noise and high operational stability, effectively improving equipment running efficiency and reducing daily maintenance frequency.
5. Medium-Precision Vacuum & Fluid Pump Equipment Applied to rotor support of small dry vacuum pumps and miniature centrifugal pumps used in industrial and laboratory environments. The phenolic cage delivers excellent heat resistance and self-lubricating performance, adapting to temperature rise during medium-high speed operation and maintaining stable sealing and rotating precision for long-term pump operation.
