1. Design & Construction
The 23960 spherical roller bearing consists of a solid outer ring with a spherical raceway, a solid inner ring, and symmetrical spherical rollers. The spherical outer ring raceway allows the bearing to be self‑aligning, accommodating angular misalignments (typically 1.5°–3°) caused by shaft bending or installation tolerances. This reduces stress on the bearing and extends service life.
Common suffixes:
CA: Symmetrical rollers with a machined brass cage. Offers high load carrying capacity and good shock resistance.
W33: Oil grooves and three lubrication holes in the outer ring enable easy relubrication, extending maintenance intervals.
2. Key Features
High Load Capacity – Optimized roller geometry and robust design provide excellent radial load capability, suitable for heavy and fluctuating loads.
Self‑Aligning – Compensates for misalignment, reducing sensitivity to mounting errors and shaft deflection.
Low Friction & Long Life – Advanced internal design minimizes frictional heat; proper lubrication significantly extends operational life.
Enhanced Lubrication (W33) – Built‑in lubrication features ensure efficient grease replenishment, critical for harsh or high‑temperature environments.

4. Applications
The 23960 bearing is widely used in heavy machinery and industrial equipment, including:
Mining & Aggregates: Vibrating screens, crushers, belt conveyors
Metallurgy: Rolling mills, continuous casting machines
Wind Power: Main shafts and gearboxes
Paper Machinery: Calenders, drying cylinders
Industrial Gearboxes & Heavy‑Duty Transmissions
Rubber & Plastic Machinery
5. Interchangeability & Selection Guide
The 23960 bearing follows ISO dimensions and is interchangeable with equivalent models from major brands such as SKF, FAG, NSK, TIMKEN, and others. When selecting, pay attention to:
Suffixes: CA (brass cage), W33 (lubrication features), or C3 (increased internal clearance) depending on operating temperature and fit requirements.
Clearance: Normal (CN) or C3 clearance should be chosen based on shaft‑housing interference and thermal conditions.
