What Are TIMKEN Spherical Roller Bearings?
TIMKEN spherical roller bearings—also known as self-aligning roller bearings—are designed to carry high radial loads and moderate axial loads in both directions. Their spherical raceway and double-row roller design make them highly tolerant of misalignment, vibration, and shaft deflection, which makes them ideal for rotating equipment under harsh or unpredictable conditions.
⭐ Key Features and Advantages
✅ Misalignment Capability
Up to ±2° self-alignment to compensate for shaft deflections and mounting errors.
✅ High Load Capacity
The large contact surface and optimized roller geometry allow for heavy radial and axial loads.
✅ Reduced Friction = Lower Energy Use
Advanced surface finishing and internal geometry reduce heat generation and energy consumption.
✅ Extended Bearing Life
Carburized steel options and advanced heat treatment resist fatigue, wear, and spalling.
✅ Available With W33 Lubrication Groove
Facilitates better grease circulation, reduces maintenance intervals, and improves reliability.
