Spherical Roller Bearings: Features, Classification, Models & Applications
Spherical roller bearings are double-row self-aligning heavy-duty rolling bearings widely used for industrial heavy-load and vibration working conditions. Featuring spherical outer ring raceways, these bearings deliver excellent self-aligning performance, high radial load capacity and stable bidirectional axial load resistance. With complete symmetric and asymmetric roller types, cylindrical and tapered bore designs, and full standard models, they serve various heavy industrial mechanical equipment stably and durably.
1. Core Bearing Features
•Dual Load Bearing Capacity: Designed with double-row rollers, spherical roller bearings mainly bear heavy radial loads and support bidirectional axial loads. They cannot bear pure axial loads, making them professional composite load bearings for industrial equipment.
•Super Heavy-Load & Anti-Vibration Performance: With optimized roller arrangement and contact structure, these bearings possess ultra-high radial load capacity, perfectly adapting to long-term heavy-load and frequent vibration working scenarios.
•Excellent Self-Aligning Ability: The spherical outer ring raceway can automatically compensate shaft deflection and coaxiality errors during operation, effectively avoiding abnormal wear and extending bearing service life.
2. Product Classification
•By Rolling Element Type: Symmetric spherical roller bearings, asymmetric spherical roller bearings
•By Inner Bore Structure: Cylindrical bore spherical roller bearings, tapered bore spherical roller bearings
