Spherical Roller Bearing 22222CCK/W33 Tapered Bore 110x200x53mm

Spherical Roller Bearing 22222CCK/W33 Tapered Bore 110x200x53mm for Heavy Mining and Paper Machinery

The 22222CCK/W33 Spherical Roller Bearing is a heavy-duty, self-aligning double-row roller bearing engineered with a 1:12 tapered bore and outer ring lubrication features. Built to withstand extreme radial loads, heavy shock, and shaft misalignment, it is widely used in mining crushers, vibrating screens, and industrial gearboxes where continuous operation and long service life are critical.

• Model: 22222CCK/W33 (Also written as 22222 CCK W33 / 22222-E1-K)
• Inner Diameter (ID): 110 mm (Tapered Bore 1:12)
• Outer Diameter (OD): 200 mm
• Width: 53 mm
• Structure: Double Row Spherical Roller Bearing (Tapered Bore, Lubrication Groove & 3 Holes)
• Material: High-Purity Chrome Steel (GCr15 / SAE 52100)
• Cage Material: Stamped Steel Cage (CC Design)

• Self-aligning capability automatically compensates for shaft deflection and housing misalignment without increasing friction.
• Tapered bore (1:12 K design) enables fast, precise mounting and dismounting on cylindrical shafts using adapter sleeves (such as H322).
• W33 lubrication groove and holes on the outer ring allow direct grease delivery to the rolling elements for cooler running.
• CC internal design features symmetrical rollers and a floating guide ring for maximum load capacity and optimized roller guidance.

• Raw material inspection: Ultrasonic flaw detection and chemical composition verification of bearing-grade chrome steel.
• Precision machining process: CNC precision grinding of spherical outer raceways and 1:12 tapered inner bores.
• Heat treatment control: Bainitic or martensitic heat treatment for superior shock load and wear resistance.
• Clearance & rotation testing: 100% verification of radial internal clearance, taper gauge fit, and rotational smoothness.
• Final inspection before delivery: Anti-rust oil coating and heavy-duty export wooden crate or reinforced carton packaging.
