NTN Ball Bearings
Ball bearings are widely used where low friction, speed capability and accurate shaft support are important. The correct style depends on the direction and magnitude of the load, speed, alignment and available space.
Deep Groove Ball Bearings
A common choice for electric motors, pumps, conveyors, gearboxes and general machinery. Deep groove designs can support radial load and some axial load.
Browse Deep Groove Ball BearingsAngular Contact Ball Bearings
Designed for combined radial and axial loading, with contact-angle options suited to applications such as machine tools, pumps and higher-speed equipment.
Browse Angular Contact Ball BearingsOther Ball Bearing Styles
Tri-State also catalogs miniature, self-aligning, thin-section, flanged and other ball-bearing styles for specialized applications.
Browse All Ball BearingsNTN Roller Bearings
Roller bearings use line contact between the rolling elements and raceways, making them well suited to many higher-load industrial applications.
Spherical Roller Bearings
Built for heavy radial loads, combined loads and applications where shaft or housing misalignment must be accommodated.
Browse Spherical Roller BearingsCylindrical Roller Bearings
High radial-load capacity and rigid shaft support make cylindrical roller bearings common in gearboxes, motors, machine tools and heavy machinery.
Browse Roller BearingsTapered Roller Bearings
Designed for combined radial and axial loads. Tapered roller bearings are commonly used in gearboxes, industrial machinery, wheel ends and other loaded rotating assemblies.
Browse Roller BearingsNeedle Roller Bearings
A compact roller-bearing design for applications that need substantial radial capacity where radial space is limited.
Browse Needle Roller BearingsThrust Bearings
Ball and roller thrust-bearing styles are used where the primary load acts along the shaft axis. Verify thrust direction, load, speed and washer or race configuration.
Browse Thrust BearingsMounted Bearing Units
Pillow block, flange, take-up and other mounted units combine a bearing insert with a housing for convenient installation and alignment.

Do not select a replacement on bearing family or dimensions alone. Confirm bore, outside diameter, width, load direction, speed, internal clearance, sealing, lubrication, mounting arrangement and the application environment. If you are replacing an existing bearing, the complete manufacturer part number is usually the best starting point.
Use the NTN bearing selection guide or contact Tri-State Bearing if the original number is missing or unclear.
