NMT Angular Contact Ball Bearings High-Speed Low-Vibration Support Bearings For Precision Equipment Under Bidirectional Loads
Precision processing equipment and intelligent automation machinery are subjected to combined radial and axial loads during operation. Ordinary deep groove ball bearings cannot withstand large axial forces, leading to axial movement after long-term operation and loss of positioning accuracy. Machine tool spindles, robot joints and precision testing instruments require extremely stable rotation. Minor bearing vibration causes processing defects and inaccurate measuring data. Continuous high-speed operation leads to excessive temperature rise, changes internal clearance and accelerates wear. The industry demands high-quality angular contact ball bearings that withstand combined loads with low vibration at high speeds.
Japan NMT optimizes the contact angle of angular contact ball bearings. Balanced contact between balls and raceways supports combined radial and axial loads. Ultra-precision grinding of raceways reduces friction and suppresses temperature rise and vibration at high rotation speed. Back-to-back, face-to-face and tandem mounting methods are available to bear bidirectional axial forces to meet diverse assembly demands. Finely heat-treated materials deliver uniform surface hardness and outstanding fatigue resistance. Precisely controlled internal clearance minimizes shaft wobble and maintains long-term precision.
Various contact angles are available for light and medium loads. Optional seals prevent dust intrusion for workshop environments. Standard dimensions enable easy replacement during equipment upgrading.
