The 231 combination of split spherical roller bearings like SKF bearings , accessible in shaft diameters of 240-450mm, is usually used in mining conveyor and stacker/reclaimer applications.“Split bearings are best for use inside ‘trapped’ bearing position of machines,” says Richard Law, Product line and Sales manager for SKF Cooper Split SRBs at SKF. “Using split bearings signifies that the drive coupling and gearbox don't need to be dismounted during bearing replacement limiting unwanted costs and downtime.”
RCM Bearing is often a leading supplier of fine quality SKF 307 Switzerland | SKF Bearings More advantage and partner in other kind FAG bearing selling.

Under precisely the same operating conditions, the operating life of X-life bearings is really a lot longer or, alternatively, higher loads may be applied while maintaining a similar rating life values. These state-of-the-art manufacturing technologies enable an even better and more uniform surface in the whole contact zone between your rolling elements and raceway. The internal construction is intended for optimum functionality using state-of-the-art analysis and evaluation methods which ensures optimized contact surface geometry and much more even internal load distribution from the bearing.
As a result, you will find there's reduction within the stress conditions present within the rolling elements and mating track under identical load. This creates a higher dynamic load rating, longer nominal rating life, less friction, lower bearing temperatures, in addition to a reduction from the strain placed about the lubricant.
Tests have confirmed that optimizing bearing positions with X-life bearings allows the general cost-effectiveness in the relevant application for being improved. The hydraulic systems utilised in wheel loader travel drives having a power transfer unit, hydraulic pumps, motors, and innumerable rolling and plain bearing positions is one example, as the complete efficiency on this application might be increased by nearly two percent. For a wheel loader with 140 kW drive power, what this means is a total saving close to 9 kW.
