In FAG split spherical roller bearings, the inner ring, outer ring and cage with the roller set are split in half. C3) are available upon request. The new range of SKF Cooper split spherical roller bearings helps customers reduce maintenance downtime, save money and improve worker safety. Split cylindrical roller bearings are completely split to the shaft. In most split spherical roller bearings, the locking rings are integrated in the inner rings, Figure9. The split bearing rings are held together by screws. Additionally the time saved and costs eliminated by not having to remove ancillary equipment results in even higher potential savings.

One problem is grease consumption; conveyors typically use standard open-pulley bearings, which require large amounts of grease to purge any contamination.

Split spherical roller bearings are primarily used for bearing positions which are difficult to access such as on long shafts which require support at several positions, or on cranked shafts. The wire cut angular inner race joints further ensure a smooth roller path.Moreover, using wire cutting as a splitting technique – rather than employing alternative methods – means that the risk for fretting corrosion with the shaft is minimized. Split ball designs are intended for applications only where pin rotation will occur. The main use of the split spherical roller bearing is in the trapped bearing position of the machine. The shaft requirements of the split bearing are the same as those needed for a standard spherical roller bearing mounted on an adapter sleeve.Ultimately, the use of SKF Cooper split spherical roller bearings can help those in the mining, quarrying and cement industries to significantly cut their maintenance costs and production losses, and reduce their environmental impact – whilst improving worker safety. Despite significant reductions, the number of injuries and fatalities that occur in the mining industry each year remains high.

The split bearing outer ring has the same dimensions as a standard spherical roller bearing and can fit into split plummer block housings with standard locating rings, if required.

There is no need to dismount the drive coupling or cantilevered drive, thus reducing the amount of equipment, such as cranes and alignment tools, that need to be rented to complete the job.Moving the conveyor belt to access the pulley, and moving the pulley and gearbox, can be very dangerous operations to carry out, as these components are often heavy and elevated above ground, thereby increasing the risk of an accident to maintenance personnel. All Rights Reserved The design of the rings, in particular, serves to enhance the performance of the bearing and increase its service life. The interlocking outer race and shroud joints not only provide good alignment of the two halves, but also reduce the risk of damage at the splits during operation. Nodes supplies FAG split spherical roller bearings, which inculdes 222S, 222SM, 230S, 230SM, 231S, 231SM, 239SM, 240SM, 241SM series. SKF Cooper split spherical roller bearings are manufactured to ISO Normal precision and running accuracy. This is partly because couplings and gearboxes on this type of equipment need to be hoisted during repair, which creates a number of risks to the safety of employees.In the mining, quarrying and cement industries, conveyors are by far the most troublesome machinery to keep running efficiently.

By contrast, in-situ replacement of a split bearing only requires the slight raising of the shaft and little or no disturbance of the drive coupling or gearbox, which greatly reduces the exposure of workers to safety hazards.As a further benefit, the use of a sealed split bearing significantly reduces the need for lubrication (approximately 90–95% less grease), resulting in reduced costs, safety risks and environmental impact.The SKF Cooper range of split spherical roller bearings can be fitted in all SKF metric (SNL, SNLD) and inch (SAF, SAFD, SDAF) split plummer block housings. Preventing the contamination of conveyor bearings, reducing the amount of lubrication they need and speeding up repair times are, therefore, crucial challenges for the mining, quarrying and cement industries. The mounted internal radial clearance of the split bearing is slightly more or less than the mounted clearance of a standard (CN) spherical roller bearing mounted on an adapter sleeve.
