Advantages of Split Cylindrical Roller Bearings Split Cylindrical Roller Bearings are essential in applications involving limited access and are highly cost effective where down time due to change-outs results in significant production losses. Split cylindrical roller bearings are completely split to the shaft. Installation and inspection times are therefore dramatically less than for solid bearings. Additionally the time saved and costs eliminated by not having to remove ancillary equipment results in even higher potential savings. Inspection Simplified No matter what the size or type of split...

Quick Reference Guide In order to provide our customers with clear and concise labelling, Timken has endeavoured to things simple when creating references. The following should cover the majority of ordering situations, however, as always, your local Timken sales engineer will be pleased to assistance if required. Additional Suffixes Bearing Size (Shaft Size) Series Prefix For most commonly used bearings this will be either; LS Light Series MS Medium Series HS Heavy Series Imperial sizes are given in inches followed by 16ths. Metric sizes are given in millimetres (mm) e.g.; 27/16 inches – 207...

Bearing Types Retained Type Bearings (BR) Expansion Type Bearings (BX) This bearing has integral flanges on the outer race to provide a surface for axial load. This axial load is accommodated on the inner race via the hardened clamp rings, which both align the inner race halves and provide roller guidance. In larger bearings the inner race is manufactured with integral ribs for roller guidance and axial load. This bearing is designed for radial loads only. As in the retained type bearing, the rollers are guided on the inner race by the hardened shoulders of the clamping rings. This type of bearing...

Support Types Support Units bearings and housings may be mounted in a variety of support units according to the application and loading constraints. A number of variants are available as standard types with other unit types available on request. offer a design and manufacturing facility to produce custom units to cover more specialized applications. Pillow Block (Support) Type This is by far the most popular method for mounting Revolvo units. These supports are manufactured from high strength, ASTM 48A grade 40 cast iron. This, combined with the robust design, provides a stable, rigid base, allowing...
