Description

‌The application of single-row spherical roller bearings with adapter sleeves mainly involves working environments that need to withstand heavy loads or vibration loads, especially in the steel, papermaking, shipping, power and other industries. ‌ 

These bearings are widely used in steelmaking converters, continuous casting machinery, papermaking machinery, lifting machinery, reducers, mining and heavy machinery due to their special structure and performance.

They can withstand radial loads and bidirectional axial loads, have good self-aligning performance, can compensate for coaxiality errors, and are particularly suitable for occasions where installation errors or angle errors caused by shaft deflection occur.
