Our premium Spherical Roller Bearings are engineered for high-performance industrial applications, featuring a drum-shaped roller assembly between an inner ring with two raceways and an outer ring with a spherical raceway. This unique geometry allows the bearing to maintain a consistent centering function, similar to self-aligning ball bearings, ensuring smooth rotation even when the shaft or housing is subjected to bending or misalignment.
Designed specifically for heavy-duty environments, these bearings excel in supporting substantial radial loads and bidirectional axial loads. With a specialized tapered bore (1:12) for convenient mounting and optional lubrication grooves (W33 type), they provide unmatched reliability and stability for machinery operating under impact loads or low-speed rotations.

Frequently Asked Questions
Spherical Roller Bearings provide much higher radial load capacity and superior impact resistance compared to ball bearings, while maintaining excellent self-aligning properties.
The W33 suffix indicates that the outer ring is equipped with a lubrication groove and three lubrication holes to facilitate easier grease or oil delivery.
No, Spherical Roller Bearings are unsuitable for carrying pure axial loads. They are designed for heavy radial loads and a small amount of axial load.
Tapered bores (1:12) allow for easier mounting and dismounting on shafts and enable the user to precisely regulate the radial clearance of the bearing.
Stamped steel is ideal for general use, polyamide for reduced friction and noise, and copper alloy for extreme temperature or harsh environments.
Our spherical roller bearings typically permit an angular misalignment within the range of 0.5 to 2 degrees, depending on the specific model.
