Timken Spherical Roller Bearings - Supplied by CNS Bearings, South India's Timken Distributor
Spherical Roller Bearing
Spherical roller bearings have matching spherical surfaces on both rings and rollers that enable the bearings to compensate for modest misalignment between a rotating shaft and the bearing housing. Spherical bearings have high radial load capacity and accommodate some combination of radial and axial loads.

What Makes Timken Spherical Roller Bearings the Choice for Heavy, Misaligned Applications?
Spherical Roller Bearings (SRBs) are designed for two defining challenges: heavy combined radial and axial loads, and shaft misalignment. The barrel-shaped rollers and spherical outer ring raceway allow the bearing to self-align, accommodating angular misalignment caused by shaft deflection, mounting errors, or thermal expansion. This makes SRBs indispensable in long shaft applications – conveyors, fans, agitators, and gearboxes – where perfect alignment cannot always be guaranteed.
CNS Bearings supplies the full Timken SRB range to industries across South India. For applications primarily driven by axial loading, see ourSRB Thrust Bearings. For high-speed applications with primarily radial loads, ourCylindrical Roller Bearingsmay be more appropriate. Browse the complete bearing range on ourProducts page.
Key Application Areas in South Indian Industry
Power generation is one of the largest application areas for Timken SRBs in South India. Induced-draft and forced-draft fans at thermal power stations operated by NTPC and NLC India run at high speeds under heavy, fluctuating loads and are subject to thermal shaft expansion. SRBs accommodate the resulting misalignment while handling loads that would overwhelm alternative bearing types.
Paper mills in Karnataka and Tamil Nadu use SRBs extensively in dryer section rolls, press section rolls, and large machine drives. Mining conveyors across South India’s mineral-rich regions depend on SRBs for long service intervals between relubrication. Cement plant equipment – rotary kilns, vertical mills, and roll presses – subjects bearings to shock loads, dust contamination, and high temperatures where Timken’s SRBs excel.
For complete housing solutions around these bearings, ourSplit Plummer BlocksandSplit Housed Unitsallow in-position bearing replacement without shaft removal. Correct installation usingTimken Maintenance Tools– particularly induction heaters for interference-fit mounting – is essential for achieving full SRB service life.
Frequently Asked Questions
Q: How much misalignment can a Timken spherical roller bearing accommodate?
A: Timken SRBs can typically accommodate angular misalignment of ±1° to ±2.5° depending on the series and size. The exact limit is stated in Timken’s product catalogue and should not be exceeded in design.
Q: Do SRBs require special lubrication?
A: SRBs can be lubricated with grease or oil depending on the application. Timken provides specific lubrication recommendations by bearing series and application. CNS Bearings can supply the relevant data sheet alongside the bearing.
Q: Are Timken SRBs available with integrated sealing?
A: Yes. Timken offers spherical roller bearings in sealed variants that are pre-greased and suited for environments where contamination control and reduced relubrication frequency are priorities.
