1. Core Application Scenarios
-
High-Speed CNC Machining Centers: Used as the non-locating (floating) rear support, or as the main front bearing in high-speed spindles cutting aluminum, wood, copper, or composites where rotational speed is prioritized over heavy axial cutting forces.
-
Precision Engraving & Milling Spindles: Ideal for molds, dies, and 3C electronics component processing. These applications require spindles to run continuously between 10,000 and 16,000 RPM while maintaining micron-level tool tip runout and low thermal expansion.
-
Grinding Machine Wheelheads: Perfect for high-speed external and internal grinding machine spindles. The 15° contact angle provides superior radial stiffness, preventing the grinding wheel from deflecting under radial cutting pressure to ensure excellent workpiece roundness.
-
High-Speed Test Rigs & Dynamos: Implemented in test benches for electric vehicle (EV) drive motors, turbochargers, and aerospace accessories, offering low operational drag and exceptional stability at extreme velocities.
2. Engineering Application & Assembly Guidelines
Bearing Arrangement (Mounting Configurations)
The ULsuffix indicates a universally matchable design with a light preload. Because a single bearing cannot support bidirectional axial forces, they are commonly mounted in these sets:
-
Back-to-Back (DB / "O" Arrangement): The most common setup. This layout maximizes the rigid span of the bearings, offering outstanding resistance to tilting moments. It is highly recommended for the front-end support of a machine tool spindle.
-
Tandem plus Counter-Bearing (e.g., TBT or QBT): Two or three bearings are stacked in parallel to support heavy axial forces from one primary cutting direction, while an opposing bearing eliminates axial play. This setup is ideal for spindles requiring high speed alongside robust single-direction feeding power.
