How does a spherical roller bearing work?
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.
Are spherical roller bearings self-aligning?
Features of Spherical Roller Bearings 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.
Where do we use spherical roller bearings?
Spherical Bearings are essential part of heavy machines like gearboxes, turbines, mechanical fans, constructions equipment, mining equipment and drilling equipment. Roller Bearings are available in multiple standard sizes and dimension yet they are also made with custom sizes and specifications.
What kind of loads can a spherical roller bearing support?
Spherical roller bearings are able to support substantial axial and radial load combinations of the rolls and cylinders used. They tolerate misalignment between the shaft and housing. Bearings should have a rated life of at least 200,000 h in the dryer section and 120,000 h (14 years) in the other sections.
Why are SKF roller bearings spherical?
Spherical roller bearings are characterized by their self-aligning ability and high load-carrying capacity. They are designed to accommodate radial load or combined radial and axial load. Invented by SKF and refined over the years, SKF spherical roller bearings provide top-of-the-line performance.
What are the types of roller bearings?
Tapered Roller Bearing.
Which bearing is used for low speed?
A variety of bearings can be used in low-speed applications, but thin section bearings and slewing ring bearings are two of the most common.
Can spherical roller bearings take thrust?
Spherical roller thrust bearings can accommodate radial loads up to 55 % of the simultaneously acting axial load. This means that one spherical roller thrust bearing can be used instead of a combination of a radial and a thrust bearing.
What is a cylindrical roller bearing?
Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
What kind of roller bearings are spherical in shape?
Spherical roller bearings Spherical roller bearings have two rows of symmetrical rollers, a common sphered outer ring raceway and two inner ring race – ways inclined at an angle to the bearing axis (ig. 1) The centre point of the sphere in the outer ring raceway is at the bearing axis
What are the features of SKF spherical bearings?
All SKF spherical roller bearings contain strong window- or prong-type cages Fig. 1 Spherical roller bearing Fig. 2 Self-aligning property of the bearing 4 Spherical roller bearings Designs and variants Designs and variants SKF standard assortment
Why are spherical bearings used in CARB bearings?
Accommodate misalignment Spherical roller bearings are self-aligning like self-aligning ball bearings or CARB bearings (ig. 2) High load carrying capacity Spherical roller bearings are designed to accommodate both heavy radial loads and axial loads in both directions
What is the clearance group for spherical bearings?
In the basic design, spherical roller bearings are produced to the clearance group CN (“normal”) (without a suffix for the internal clearance). In order to take account of the different operating and mounting conditions, we can also supply bearings with a larger radial internal clearance by arrangement.
