FAG split spherical roller bearings

 FAG split spherical roller bearings can make bearing replacement easier and faster, especially in very difficult position while in replacement of bearings. In the split bearing, inner ring, outer ring and roller cage assembly is divided into two, and clamped together by bolts. Using split bearings, installation and removal of many steps can be omitted. This means downtime is significantly reduced, bring in significant cost savings. Because the same size, so split spherical roller bearings can be installed in same place compared with integral bearings (including tight sets). Applications include belt drives, paper machinery, shipbuilding, and transportation equipment, converter, related to the rolling and ventilation systems.

 The improvements of split
In many applications, the installation of self-aligning roller bearings on the shaft is very complex, while replacing bearings, all of the adjacent parts are required to be removed. This will result in a longer downtime and complex extra tasks such as removing the gears, clutch and transmission unit. In addition, there are additional costs such as replacement parts, tools, labor and crane rental. While for split bearings, most of the processes and the cost can be omitted. Installation and removal will become more rapid and simple, especially hard to reach parts of the bearing installation. Schaeffler offers shaft diameter from 55 mm to 630 mm split spherical roller bearing. In most cases, the outside diameter, outer ring width and shaft diameter of split spherical roller bearings is matched with standard spherical roller bearings (including tight sets), so these two bearings can be interchanged without problems.

  Applications: Split Spherical Roller Bearings installation for the chemical exhaust fan
A chemical plant exhaust fan Spherical roller bearings need to be replaced, its’ outer diameter is 230 mm. In the past, replace one unsplit bearings needs 14 hours downtime each time. it resulting in about 28 million euros costs. In addition, the cost also includes a large number of lost production, labor costs, the extra cost of shaft alignment, crane rental and other need to .If use FAG split spherical roller bearings, downtime is only three hours, with a total cost of 60,000 euros. Commissioning, crane rental and other bearing replacement is no longer needed. Therefore, customers can save about € 220,000 spending.
