Timken® Single Row Cylindrical Roller Bearings
Timken single row cylindrical roller bearings are built for critical industrial applications requiring high radial load capacity and thermal expansion. Available in premium brass cage, steel cage, full-complement designs, and ETP Series with a lightweight polymer cage, these bearings deliver proven, reliable performance and expanded performance for compact, high-performance applications. /Asset/Single-Row-Cylindrical-Roller-Bearings-Main_Family-Picture-2026.jpg Timken® ADAPT™ Roller Bearings
(84) TTimken ADAPT bearings combine the traditional cylindrical roller bearing and spherical roller bearing configurations. Its proprietary outer race and roller profiles plus a cylindrical inner ring combine the key attributes of both bearing types. This unique three-point contact design geometry provides simultaneous misalignment and axial displacement performance, optimizes contact stress distribution, and helps promote roller stability. The result is a more dynamic, more reliable bearing. /Asset/ADAPT-Main-Family-Picture-2026.jpg Timken® Double Row Cylindrical Roller Bearings
(58) Timken two-row, or double-row, cylindrical bearings are designed for additional strength in carrying radial loads. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard. Double row full complement cylindrical roller bearings are also available to meet the need for radial load carrying capacity. /Asset/Double-Row-Cylindrical-Roller-Bearings-Main_Family-Picture-2026.jpg Timken® Four-Row Cylindrical Roller Bearings
(104) Timken four-row cylindrical roller bearings are engineered for maximum performance in demanding applications that require high radial load capacity and durability. Their advanced multi-row design allows for optimal distribution of loads, reduced friction, and long service life even under continuous, high-speed operation. These bearings are the trusted choice due to their reliability and exceptional wear resistance. /Asset/Four-Row-Cylindrical-Roller-Bearings-Main_Family-Picture-2026.jpg Timken® Cylindrical Roller Radial Bearings - 5200, A5200 Metric Series
(26) The radial internal clearance (RIC) for the bearing assembly must be included when ordering either a) the complete assembly or b) with the inner-ring set. /Asset/timken-A-5224-WS-TheTimkenCompany-3D-06-27-2022-left-angle-view.jpg Timken® Cylindrical Roller Radial Bearings - HJ Series
(20)- Clearance fit suggested for outer ring when housing is stationary relative to load.
- Tight transition fit suggested if housing rotates relative to load.
- Consult your Timken representative for oscillating applications (e.g., low radial-clearance concerns).
- Unmarked end of outer ring should be assembled against housing shoulder to clear maximum allowed housing fillet (ras max).
- Meets Military Standard MS 51961.
Timken® Inner Ring (IR)
(24)- Ideal choice where the shaft is not practical to use as inner raceway.
- Designed to meet established inch tolerances.
- Maximum shaft fillet radius cannot exceed inner-ring bore chamfer as shown.
- Optional centralized lubrication groove (bore) or through hole available – specify when ordering.
- Designed to be axially clamped against shoulder for loose transition fit on shaft.
- After mounting, for tight transition fit (keeping inner ring from rotating relative to shaft), inner-ring O.D. must not exceed raceway diameter on matching bearing.
- After mounting, if O.D. of inner ring exceeds the required raceway diameter for matching bearing, ring should be ground to proper diameter while mounted on shaft.
- Unmarked end of inner ring to be assembled against the shaft shoulder to ensure clearing the maximum allowable shaft fillet as indicated in tables shown.
