23944.EMW33C3 Double‑Row Spherical Roller Bearing 220*300*60mm For Mining Crusher
Product Overview
23944.EMW33C3 is an open‑type double‑row spherical roller bearing. It adopts upgraded E‑type roller structure, solid machined brass retainer and C‑3 enlarged internal clearance. An outer‑ring lubriion groove plus three oil holes support convenient re‑lubriion. The self‑aligning characteristic compensates shaft deflection, and it can bear heavy‑duty radial and bidirectional axial loads, suited for crushers, cement equipment and other harsh‑condition industrial machinery.

FAQ
Q1: What do the common suffix markings E, W33 and C3 represent?
A1: E means upgraded‑optimized internal roller design, W33 stands for outer‑ring lubriion groove and three oil holes, C3 refers to widened radial internal clearance.
Q2: Why do these spherical roller bearings adopt C3 internal clearance?
A2: The expanded radial clearance compensates thermal expansion of bearing steel during long‑time high‑temperature and heavy‑duty running.
Q3: Are these bearings able to tolerate shaft mounting deviation?
A3: Yes, the spherical raceway‑type structure delivers stable self‑aligning capacity to adapt minor shaft deflection and installation misalignment.
Q4: What kinds of loads can these spherical roller bearings support?
A4: They mainly undertake heavy radial loads, as well as moderate bidirectional axial loads generated by heavy‑duty transmission shafts.
Q5: What practical benefit does the W33 lubriion groove bring?
A5: Workers can inject fresh grease or oil via the outer‑ring oil holes directly, without disassembling the installed machinery.
