22324 CA/C3W33 Spherical Roller Bearing 120x260x86mm Brass Cage C3 Clearance With W33 Lubrication Groove

22324 CA/C3W33 double row spherical roller bearing, standard metric dimension 120×260×86mm.

Model Code Definition

• 22324: Heavy-duty wide 223 series spherical roller bearing size specification
• CA: Inner ring with two integral retaining ribs, symmetrical rollers, solid machined brass roller-guided cage
• C3: Enlarged radial internal clearance, specially matched for high-temperature, heavy-load running conditions
• W33: Outer ring with annular lubrication groove and three evenly distributed relubrication holes for convenient on-site grease replenishment

This bearing adopts double-row symmetrical spherical roller structure, outer ring spherical raceway delivers excellent self-aligning performance to compensate shaft deflection and installation misalignment. It can bear combined heavy radial load and bidirectional moderate axial load simultaneously. Solid brass cage ensures stable roller positioning under severe vibration, impact and continuous high-temperature operation. W33 lubrication structure greatly extends maintenance cycle and service life. Widely applied in mining crushers, cement ball mills, rotary kilns, heavy mixers, paper machinery, steel metallurgical equipment, large conveyors and heavy-duty industrial reducers.

Technical drawings, load characteristic curves and long-cycle fatigue durability test reports are available upon formal request.

1. Powerful self-aligning property: Spherical outer raceway allows up to 0.5° angular misalignment, eliminate additional internal stress caused by shaft bending or assembly deviation
2. CA solid brass cage: High tensile strength, anti-fatigue and heat-resistant, no deformation under long-term heavy shock and vibration, stable roller operation
3. C3 enlarged internal clearance: Reserve sufficient expansion space for thermal elongation of rings and rollers, effectively avoid bearing seizure at high working temperature
4. W33 integrated relubrication structure: Circumferential oil groove plus three lubrication holes, realize uniform grease distribution inside bearing, reduce wear and extend maintenance interval
5. Symmetrical logarithmic crowned rollers: Uniform stress distribution, eliminate edge stress concentration, improve anti-fatigue performance and prolong service life
6. Dual load bearing capacity: Handle heavy radial load and bidirectional axial load at the same time, suitable for complex composite load working conditions
7. Globally unified ISO standard dimensions, fully interchangeable with mainstream imported equivalent bearings for convenient aftermarket replacement
8. Complete customizable service: Adjustable internal clearance, high-temperature resistant special grease, outer ring anti-corrosion coating, customer exclusive laser marking
