For heavy rotating equipment where shaft deflection or housing settlement is expected, LINK-BELT spherical roller bearings provide a self-aligning solution. Their two rows of rollers and spherical outer raceway support high radial loads and moderate axial loads in both directions, while accommodating misalignment without sacrificing capacity. Common applications include conveyors, crushers, mills, vibrating screens, and large pumps in mining, cement, and material handling.

The LINK-BELT spherical roller bearing line uses an LB prefix followed by four digits. The first two digits after LB indicate the series: 68 for the 6800 series and 78 for the 7800 series, which offers higher load ratings. The last two digits specify the size within that series. For instance, LB6823, LB6824, LB6827, and LB6828 are all 6800 series bearings with progressively larger shaft diameters. Similarly, LB6831, LB6832, LB6835, and LB6839 follow the same pattern, where the final number increases with bearing size.

These bearings are selected for support points that must endure shock loads and continuous operation. In conveyor systems, rotary kilns, gearboxes, and road machinery, the self-aligning feature reduces edge stresses caused by misalignment. When specifying a bearing, consider radial and axial load, speed, sealing needs, and internal clearance. For dusty or wet environments, proper seals or shields help protect the raceways and rollers. Although the bearing tolerates misalignment, excessive shaft deflection can still accelerate wear, so alignment and housing condition remain important.

Spherical roller bearings from different manufacturers often share standardized boundary dimensions, making interchangeability possible if shaft diameter, outer diameter, width, and cage type match. However, internal clearance and factory lubrication can differ, so verification is recommended before substituting. When requesting a quote, provide the full LB part number or the shaft and housing dimensions to help identify the correct item.
