Spherical roller bearings are a type of rolling bearing with a spherical outer ring that offers self-aligning capabilities. They are commonly used in conjunction with various types of bearing housings and can automatically compensate for installation misalignment, shaft deflection and misalignment issues, making installation and commissioning straightforward. They offer excellent overall sealing, providing effective protection against dust and water, and are suitable for harsh operating conditions such as dusty and damp environments. Capable of withstanding substantial radial loads and moderate axial loads, they are widely used in sectors including agricultural machinery, conveying equipment, textile machinery, fans and mining machinery. They are characterised by their versatility, durability, reliability and ease of maintenance.
