Roller Bearings
Cylindrical, tapered, and spherical — all major brands sourced. Fast quotes, competitive pricing from an independent supplier.
Size Series We Stock & Source
From light-duty cylindrical rollers to heavy-load spherical and tapered designs — metric and inch dimensions.
Cylindrical Roller Bearings (NU, NJ, NUP, N Series)
High radial load capacity with low friction. Used in electric motors, gearboxes, pumps, and compressors. Available in single-row and double-row configurations, with various inner ring designs (NU, NJ, NUP, N) to accommodate axial displacement or provide axial location.
CST Bearing Co. is an independent bearing supplier in Santa Ana, California, sourcing roller bearings from every major manufacturer. Cylindrical, tapered, spherical — whatever your application demands, we quote fast and ship faster. Whether you need a standard tapered roller for a conveyor rebuild or a spherical roller bearing for heavy rotating equipment, CST has the supply chain to get it to you
Tapered Roller Bearings (Metric & Inch)
Spherical Roller Bearings (22000, 23000 Series)
Handle combined radial and axial loads simultaneously. The go-to design for industrial gearboxes, rolling mills, conveyor systems, and heavy machinery where thrust loads are present. Available in metric series (30000, 32000, 33000) and inch-dimension Timken-style designations (L44, LM48, HM88, 300 & 400 series, and more). Single-row, double-row, and four-row configurations.
Self-aligning design that tolerates shaft deflection and misalignment. Essential for heavy-duty applications like vibrating screens, crushers, mining equipment, paper mills, and large fans. Very high radial load capacity with moderate thrust capability.
Compact roller bearings with high load capacity relative to their cross-section. Drawn-cup and heavy-duty series for applications where radial space is limited. See our dedicated Needle Bearings page for full details.
Needle Roller Bearings
Common Applications
Roller bearings are specified wherever loads exceed what ball bearings can handle.

Conveyor systems — tapered and spherical rollers in pillow block housings
Mining & crushing equipment — spherical rollers for heavy loads with misalignment
Paper & steel mills — large spherical and cylindrical rollers in roll neck positions
Pumps & compressors — cylindrical rollers where precision and speed matter
