Spherical roller bearings feature two rows of symmetrical barrel rollers running in a common spherical outer ring raceway. This unique structure makes them inherently self-aligning, allowing them to tolerate heavy shaft deflections and angular misalignments without increasing internal friction.
These industrial giants are crucial for severe-duty applications: gearboxes, pulp and paper mills, wind turbines, mining conveyors, and cement mixers. BMT Impex maintains extensive stocks of both steel cage (Type 1) and machined brass cage (Type 2) configurations to support immediate maintenance dispatches.

Understanding the technical suffixes, clearance prefixes, and material ratings used in industrial procurement.
Critical engineering parameters, structure details, and operating limits to help you select the ideal component.
Features two rows of symmetrical barrel-shaped rollers that rotate on a common spherical outer ring. Allows up to 2° of shaft misalignment without increasing friction or heat generation.
CA brass cage configurations are engineered to resist high centrifugal forces and shock vibrations. CC steel cages are optimized for higher operating speed limits and lower torque.
The ultimate component for heavy mining machinery, paper mill rollers, wind turbines, and cement crushers. Supports heavy radial loads and high combined axial loads in both directions.
These bearings are engineered to deliver reliable rotation and support critical equipment in harsh sectors, including:
Withstands extreme shock loads and strong structural vibrations inside quarry vibrator screens.
Maintains alignment and supports heavy main shafts inside wind power generator gearboxes.
Performs reliably under intense heat and massive structural loads in steel continuous casting lines.
Compensates for hull deflections and shaft misalignments inside large commercial vessels.
