22312E Double Row Spherical Roller Bearing E Optimized High Capacity Straight Bore 60x130x46mm Mining Crusher Heavy Equipment

22312E is double row E-type optimized high-capacity spherical roller bearing with straight cylindrical bore, standard dimension 60×130×46mm. The E optimized internal structure removes inner ring central rib and adopts longer crowned rollers, greatly improving dynamic load capacity and fatigue life compared to standard bearings. Spherical outer raceway provides excellent self-aligning performance to compensate shaft deflection and assembly misalignment. It can bear heavy combined radial load, bidirectional axial load and severe impact shock. Equipped with outer ring W33 lubrication groove and oil holes for convenient regreasing, widely used in stone crushers, mining conveyors, concrete mixers, heavy gearboxes and construction rotary equipment.

• E upgraded internal structure: longer crowned rollers without inner central rib, dynamic load increased by 20%-30%, longer service life under heavy load
• Spherical outer ring self-aligning design, allows ±0.5° angular misalignment without abnormal heat and friction
• Double symmetrical roller rows carry heavy radial and bidirectional axial combined load, outstanding anti-shock and anti-vibration performance
• Outer ring built-in W33 lubrication groove and oil holes, supports regular on-site grease replenishment
• Stamped steel cages feature strong impact resistance, stable operation in dusty, harsh heavy-duty environments
• Two optional structures: straight bore 22312E for stepped shafts; tapered bore 22312EK matched adapter sleeves for smooth shafts
• C3/C4 enlarged clearance customizable for high-temperature continuous mining production lines

This 22312E high-capacity spherical roller bearing is widely applied in:

• Mining jaw/cone crushers, mineral processing rotary equipment and long-distance belt conveyors
• Cement concrete mixers, kiln auxiliary rollers and heavy stirring transmission assemblies
