Spherical Roller Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction. They are also extremely resistant to shock loads and their self-aligning feature allows full capacity loading despite shaft deflection.
Spherical bearings are used in countless industrial applications, where there are heavy loads, moderate speeds and possibly misalignment. Some common application areas are gearboxes. wind turbines , continuous casting machines, material handling, pumps, mechanical fans and blowers, mining and construction equipment ,pulp and paper processing equipment, marine propulsion and offshore drilling, off-road vehicles product specifications for spherical roller bearings include Standard bearings that are provided as open and can be sealed upon request Many clearance options to choose from Standard bearings are rated up to 302 degrees Fahrenheit Being primarily supplied with either a steel cage or a machined brass cage The option of a tapered bore SKF Bearings that are manufactured in normal tolerance class Dealing with very heavy radial and axial loads in applications prone to misalignment or shaft deflections can be a real challenge. Meet the challenge with SKF spherical roller bearings. Their high load carrying capacity and ability to accommodate misalignment helps you obtain low maintenance costs and long bearing service life. We offer a wide range of robust spherical roller bearings in both open and sealed variants.
Slow and steady works for more than just races. SKF Spherical roller bearings work best in low- to medium-speed applications, and can perform well in tough environments. Self-aligning characteristics allow spherical roller bearings to accept deviations in shaft misalignment. They are self-aligning because the center of curvature of the outer ring raceway surface coincides with the bearing axis.
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a (barrel like) profile that makes them appear like cylinders that have been slightly over-inflated
They are very similar in purpose to Self-Aligning Double Row Ball Bearings, except the Spherical Roller Bearings are designed to be more robust by carry heavier loads but at lower maximum speeds. These bearings have barrel-shaped rollers between the inner ring, which has two raceways, and the outer ring which has one spherical raceway.
