Description: The needle-mill spindle bearing is a high-speed rotating component of the needle mill. It supports the spindle and rotating disc, carries radial and part of the axial impact load, ensures smooth spindle running, reduces rotational friction, and guarantees the slurry-grinding dissociation effect.
Supports the high-speed spindle, carries radial and axial forces from the rotating disc and material impact, and constrains spindle radial runout.
Reduces rotational friction and temperature rise, keeps a stable gap between the rotating and stationary discs, and prevents disc clash.
Maintains dynamic balance to reduce overall machine vibration and noise.
Self-aligning roller bearings / angular-contact ball bearings are typically paired for high-speed, impact duties; a sealing structure prevents starch slurry and dust from entering the bearing cavity.
