SPHERICAL ROLLER BEARINGS

Spherical roller bearings consist of an outer ring having a continuous sperical raceway centered within and two rows of barrel-shaped roller operating in seprate raceway grounds ground into the inner ring with a center rib to guide the roller. This type of bearing has a self aligning nature. So, it can be used in cases where misalignment between the inner and outer ring occur from shaft mounting error of shaft deflections.
The allowable misalignment for these bearings, being varied due to the dimensional series and loading conditions, is about 0.0009 radian (0.5′) for ordinary loads, this angel can be upto 0.035 radians (2′).
These bearing have a large capacity of radial loads, axial loads in either direction, and combinations of these loads. They are also suited for applications where vibration and/or impact forces are encountered.

There are other types or bearings having cylinderical or taper bore diameters. Bearings with tapered bore diameters are specified by attaching the suffix “K” at the end of the basic number. The taper is generally 1/12, however, a taper of 1/30 is made for bearings of series 240 and 241 which are specified by attaching the suffix “K-30” at the end of the basic number. In most cases, bearings with tapered bore diameters are mounted on the shaft by means of an adapter or withdrawal sleeve. When the outer diameter of spherical roller bearings is 320mm or more, an oil hole and oil groove provided in the outer ring to supply lubricant.

• Spherical roller bearings with cylindrical or tapered bore diameters.
• Tapered bore bearings have a suffix “K” in the basic number, with a taper generally of 1/12 and 1/30 for series 240 and 241 (suffix “K-30”).
• Larger bearings (outer diameter ≥ 320mm) may feature an oil hole and oil groove in the outer ring for lubrication.

• Self-aligning nature to accommodate misalignment between inner and outer rings.
• Large capacity for radial and axial loads in both directions, including combinations of these loads.
• Suitable for applications with vibration and/or impact forces.

Allowable misalignment varies based on dimensional series and loading conditions:

• Ordinary loads: Up to 0.0009 radians (0.5′) of misalignment.
• Certain conditions: Up to 0.035 radians (2′) of misalignment.

• Cases where misalignment occurs from shaft mounting errors or shaft deflections.
• Applications with radial and axial loads, including those encountering vibration and impact forces.
