The LINK-BELT spherical roller bearing is a self-aligning component with two rows of rollers, designed to withstand high radial loads and moderate axial loads in both directions. Its spherical outer raceway allows the shaft to misalign without losing load capacity, which simplifies mounting and absorbs shaft deflection or housing settlement. It is used in mining, cement, steel and material handling equipment, where conditions are severe and lubrication must remain stable.

The LINK-BELT designation of this family is read as LB followed by four digits. The first two digits indicate the series: 68 corresponds to the 6800 series and 78 to the 7800 series, which groups bearings with higher capacity. The last two digits define the size within the series. For example, LB6823, LB6824, LB6827 and LB6828 belong to the 6800 series with different shaft diameters. In the examples LB6831, LB6832, LB6835 and LB6839 the same criterion is repeated: the final number increases with size. This nomenclature allows the series and size to be identified quickly without measuring the bearing.

In Argentine industry, these bearings are found in conveyor belts, mills, crushers, vibrating screens, rotary kilns and large pumping equipment. They also appear in road machinery, cranes and gearboxes subjected to shock loads. Their self-aligning capacity makes them suitable for long shafts that suffer deflection, where a rigid bearing would not tolerate misalignment. In cement, mining and steel plants they are a common choice for critical support points that must keep rotating with spaced maintenance.

To select the correct bearing, take into account the radial and axial load, the rotation speed and the type of sealing required. Internal clearance and lubrication must be defined according to the working temperature and the mounting method. In applications with dust or moisture, it is advisable to choose seals or oil seals that protect the raceway and the rollers. Initial shaft alignment and housing settlement influence service life: excessive misalignment, even if the bearing tolerates it, accelerates raceway wear. Mounting with the right tools prevents damage to the rings.

Spherical roller bearings from different brands share standardized dimensions, so they are usually interchangeable if the shaft diameter, outer dimensions and cage type match. When requesting a quote, it is advisable to indicate the full part number and, if possible, the main dimensions and the type of sealing. MR Accesorios Industriales supplies LINK-BELT as an official brand and can advise you on the equivalence with other nomenclatures. Not all variants have the same clearance or the same factory lubrication, so technical verification is important before replacing.

If you need a LINK-BELT spherical roller bearing, write to us on WhatsApp with the LB part number shown on your equipment or with the shaft and housing dimensions. At MR Accesorios Industriales we will quote shortly and tell you the compatible alternative if needed. We can also advise you on mounting and lubrication so that the bearing works under the conditions for which it was designed.
