Description

  • Robust Spherical Roller Design: The 22334 series (including 22334MW33 and 22334KMW33) features a spherical outer ring raceway and symmetrical barrel rollers, enabling automatic self-alignment to compensate for shaft deflection and housing misalignment up to 0.5°–2°. This design ensures reliable operation in heavy machinery where structural flexing is common, such as mining conveyors, crushers, and construction equipment.
  • High Load Capacity & Durable Construction: With dimensions of 170mm bore × 360mm OD × 120mm width, these bearings support extreme radial loads (dynamic load rating ~1,600–1,760 kN) and moderate axial loads in both directions. Manufactured from high-carbon chromium steel (GCr15) with a solid brass or steel cage (M/MW33), they offer superior wear resistance and fatigue strength for prolonged service in harsh industrial environments.
  • Optimized Lubrication & Variants: The W33 suffix indicates an outer ring with a lubrication groove and three oil holes, enhancing grease distribution and extending maintenance intervals. The "K" variant (22334KMW33) features a tapered bore (1:12 taper) for secure mounting on adapter sleeves (e.g., H2334) or tapered shafts, while the cylindrical bore version (22334MW33) suits direct shaft fits. The legacy designation 3634H corresponds to this series in older Chinese standards.
  • Precision Engineering for Heavy-Duty Use: Engineered for industrial-grade applications, these bearings operate at reference speeds up to 1,400 rpm (grease) and 1,800 rpm (oil), with a fatigue load limit of ~176 kN. Their optimized internal geometry reduces friction and heat generation, ensuring stable performance under heavy loads and variable operating conditions.
  • Versatile Applications in Demanding Sectors: Widely used in mining (vibrating screens, gearboxes), construction (excavators, cranes), metallurgy, and pulp/paper machinery, the 22334 series delivers reliability in high-shock and high-vibration environments. The robust cage design (M/MW33) resists deformation, making it ideal for vibratory equipment and heavy-duty rotary systems.
