22220KMW33/C3 Spherical Roller Bearing 100x180x46mm 1:12 Taper Bore W33 Lubrication Groove C3 Clearance Heavy

1. Product Overview

22220KMW33/C3 is double row metric spherical roller bearing, overall dimension 100×180×46mm. K represents 1:12 tapered inner bore, matched with adapter sleeve for quick installation; W33 stands for annular lubrication groove plus 3 oil holes on outer ring for convenient on-site relubrication; M machined brass cage improves roller stability under heavy vibration; C3 enlarged radial clearance adapts high-temperature, high-speed and vibration working conditions. Spherical outer raceway compensates shaft deflection and assembly misalignment up to 1.5°, bears heavy combined radial and bidirectional axial loads, widely applied to mining crushers, vibrating screens, large industrial fans, cement rotary kiln auxiliary parts and heavy conveyors.

3. Core Advantages

• 1:12 tapered inner bore, installable via adapter sleeve without heating shaft, easy disassembly and replacement
• W33 integrated lubrication groove and oil holes support continuous supplementary lubrication to extend service life
• M solid machined brass cage holds rollers firmly, stable operation under long-term severe vibration and shock
• C3 enlarged clearance eliminates thermal expansion jamming for high-temperature and vibrating equipment
• Excellent self-aligning performance offsets shaft bending and assembly offset to avoid abnormal wear
• Double row reinforced spherical roller structure carries ultra-heavy radial and bidirectional axial composite loads
• Standard metric interchangeable dimension, support custom clearance, high-temperature grease and laser marking

4. Application Scenarios

• Mining equipment: Stone crushers, vibrating screens, mine belt transport conveyors
• Industrial ventilation: Large centrifugal fans, blowers and dust removal air handling units
• Building material machinery: Cement mixers, rotary kiln auxiliary transmission rollers
• Metallurgy & heavy industry: Heavy conveyors, paper making machinery, large reducers

Fit OEM assembly and aftermarket replacement of heavy vibrating industrial equipment with high working temperature and misalignment risks.
