Spherical Roller Bearings
Spherical bearings are designed to manage high radial loads even when misalignment, poor lubrication, contamination, extreme speeds or critical application stresses are present.
Design Attributes:
Expertly designed critical dimensions such as roller and raceway contact geometry and topography improve bearing performance.
Dimension
Overall dimension of bearing listed in bearing table accords to ISO015-1981.
Angular alignment tolerance
Self-aligning roller bearing is designed in such a way that it is self-aligning .That means that bearing can and inner ring rotates ,the unsymmetrical value listed in below table is allowed Achieving completely specified value is subject to design and seal type of configured bearing .Tolerance
TG self-aligning roller bearing with cylindrical bore or tapered core is of common tolerance level.Internal clearance
According to TG standard self-aligning roller bearing is of common tolerance level in internal clearance .Bearings with dimension less than common level: C2clearance can also be supplied .please consult first to check supply status for bearing with non-standard radial clearance (including C5) .These clearance values are use for zero load testing and shaft. with remains uninstalled .Structure
Besides CA type TG can provide CC and MB structure for special. Please contact with TG for details.
