Slewing bearings enable smooth rotation of heavy loads under axial, radial, and moment forces. Used in construction, wind turbines, robotics, and more, they ensure precision, durability, and structural integration in demanding industrial applications.

THB resolved a waterjet equipment positioning issue caused by inadequate bearing selection and insufficient axial rigidity. By replacing standard double-row angular contact bearings with specialized ball screw support bearings and optimizing the positioning structure, bearing service life increased up to 3.77 times, from 862 hours to 3,254 hours.

Bearing failure in food & beverage production lines stems from improper fit selection, not quality defects. THB identified two root causes — fretting wear from loose fit and S-shaped ball motion from shaft deflection — and provided five engineering solutions to restore bearing performance.
[Insights]
Eccentric loading in stamping lines causes bearings to fail prematurely. Offset loads, impact, and roller misalignment create edge stress concentration, leading to spalling, heat, vibration, and unplanned downtime.

[Insights]
Proper grease lubrication is essential for crossed roller bearing performance. Grease reduces friction, prevents metal contact, and suppresses noise. Avoid mixing grease types, always clean before replacement, and select seasonally appropriate grease. Strict cleanliness and proper storage are critical to prevent contamination and deterioration.
