PC450 Slew Bearing
2. Product Structure: A three-row roller combination design: Two horizontal rows of rollers carry axial loads and overturning moments, while a vertical row of rollers handles radial loads. This optimizes load distribution and offers a load capacity far exceeding that of single- or double-row bearings.
3. Size Range: Outer Diameter: Approximately φ1500mm - φ2000mm; Inner Diameter: Approximately φ1200mm - φ1600mm; Number of Teeth: 84 (common size, such as 84T);
Mounting Holes: 35-40 bolt holes (depending on design requirements)
4. Material: Ring material: High-strength 50Mn or 42CrMo alloy steel
Rolling elements: High-precision, high-hardness GCr15 bearing steel balls
Seal strips: Oil-resistant and wear-resistant nitrile rubber (NBR) seals
5. Applications: PC450 and other excavators of similar tonnage (such as Komatsu PC450, Caterpillar, Hitachi, etc.), mining excavators, loaders, crushing station rotary platforms, heavy cranes, stackers and reclaimers, and port loading and unloading equipment

Premium Materials for Maximum Durability
High-Strength Ring Construction
We manufacture bearing rings using 50Mn or 42CrMo alloy steel. These materials provide exceptional strength and fatigue resistance. Your bearing will withstand years of heavy-duty operation without premature wear.
Precision Rolling Elements
Our rolling elements utilize GCr15 bearing steel with superior hardness properties. Each roller undergoes strict quality control during production. This ensures smooth rotation and extended service life.
Advanced Sealing Technology
Oil-resistant NBR seals protect internal components from contamination. These seals maintain lubrication integrity in harsh operating environments. Your bearing stays protected from dust, moisture, and debris.
Wide Application Range
Your PC450 Slew Bearing fits multiple equipment types beyond Komatsu excavators. Compatible applications include:
- Caterpillar and Hitachi excavators of similar tonnage
- Mining excavators operating in extreme conditions
- Heavy-duty loaders and material handlers
- Crushing station rotary platforms
- Port loading and unloading equipment
- Industrial cranes and stackers
