Double-rowed spherical roller bearings are the workhorse of the industry. Their barrel shaped rollers and spherical outer ring raceway permits this bearing to operate with misalignment with no reduction in bearing life. Spherical roller bearings are used mostly in heavy duty industrial applications where extreme radial loads exist. They also excel in handling axial loads in either direction, contaminated environments, misalignment, shock loads and vibration. Nachi Sphericals are manufactured in a number of design and material configurations depending upon the type of application and the size of the bearing. Most come standard with a lubrication groove and holes (W33) on the OD of the outer ring. Symmetrical or Asymmetrical (A) rollers may be used with stamped steel or machined brass cages. The "EX" design uses larger diameter rollers for the highest load ratings. All bearings are heat stabilized to at least 200 deg C (about 400 deg F). Some sizes may be available with tapered bores (K). Depending upon design, stamped steel or machined brass cages are used. Commonly used in gearboxes, wind turbines, pumps, mining/construction, marine propulsion and drilling equipment. Long life. Low friction/torque. Low operating temperature. Reduced noise and vibration. Improved roller roundness and raceway accuracy. Enhanced surface finishes result in improved lube film. Self-aligning in low and high speed applications. Press fitting adapter sleeves make internal clearance adjustment.
How do I choose the right type of bearing for my application?
Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
