Revolutionary split spherical roller bearings launched



The new range of SKF Cooper slotted spherical roller bearings help customers reduce maintenance downtime, save money and improve worker safety.

Most of the advancements in split bearing technology have been incremental improvements over the past 100 years. However, with the introduction of the SKF Cooper Slotted Spherical Roller Bearings, a new level of product quality and precision engineering have been achieved by combining SKF spherical roller bearings with SKF Cooper’s slotted bearing expertise. Manufactured at SKF Cooper in the UK, the new range of split bearings allows customers to significantly reduce downtime by replacing solid bearings on site.

The SKF Cooper range of slotted spherical roller bearings is currently available in the 231 series for shaft diameters from 240 to 450mm, which are typically used in mining conveyor and stacker / reclaimer applications. Later in the year, smaller sizes will be introduced, suitable for the quarry sector.

“Split bearings are ideal for use in the ‘trapped’ bearing position of machines,” says Richard Law, SKF Cooper split bearings product line and sales manager at SKF. “By using separate bearings this means, for example, that the drive coupling and gearbox do not need to be disassembled when replacing the bearings, reducing unwanted costs and downtime. ‘stop. “

The new bearings, available in both open (unsealed) and sealed versions, offer many benefits including a much shorter Mean Time to Repair (MTTR) as they can be replaced in situ. They also offer a reduced maintenance load, reduced production losses due to planned and unplanned downtime and, as a result, increased worker safety.

The sealed version increases reliability through better dirt exclusion and allows lower grease consumption, reducing the impact on the environment. These new bearings also offer superior shaft fit and operate at lower noise and vibration levels.

The excellent performance of SKF Cooper slotted spherical roller bearings is the result of several innovative design features, including: tight ductile steel for more secure positioning and wire-cut inner and outer rings for superior raceway geometry. A precision manufactured sawtooth seal on the bearing outer ring improves axial alignment and allows for a reduced outer ring section.

In mining, the main advantage is that MTTR is typically reduced from 24 hours to 8 hours in conveyor systems. In addition, by reducing the number of maintenance steps, such as overhead lifting of heavy line equipment, it will also reduce the risk to workers. The new bearings can also be applied in other industries such as mineral processing, cement and metal processing. As the size range expands, applications will expand to other processing industries and ancillary equipment, such as industrial fans.
