Product Introduction: Bearing-Self-Aligning 3321648 for Caterpillar Equipment
Overview
The Bearing-Self-Aligning 3321648 is a precision-engineered spherical plain bearing designed for Caterpillar equipment, specifically used to reduce friction and accommodate misalignment in oscillating hitch assemblies. This component is critical for ensuring smooth operation and durability in demanding applications, primarily articulated trucks. Available as a new aftermarket or genuine OEM part, it provides a reliable and cost-effective solution for equipment maintenance.
Key Features
- Material: Constructed from high-strength bearing steel, designed to withstand heavy radial and axial loads, resist wear, and perform reliably in harsh operating conditions. Features a corrosion-resistant coating to protect against rust and wear.
- Design: Precision-engineered self-aligning spherical bearing, built to OEM specifications for precise fitment and performance. The spherical design allows for misalignment adjustment, ensuring smooth movement and optimal load distribution in oscillating hitch assemblies.
- Compatibility: Compatible with Caterpillar equipment, specifically:
- Articulated Trucks: 735, 735B, 735C, 740, 740B, 740C, 740 GC, 745, 745C.
- Ejector Trucks: 740, 740B. Typically used in Hitch GP-Oscillating assemblies to support dynamic loads and misalignment. Exact model compatibility must be verified using the equipment’s serial number via CAT SIS, as compatibility cannot be confirmed without it per Caterpillar’s policy.
- Dimensions: Features an outer diameter of 120.65 mm (approximately 4.75 inches), per OEM specifications for articulated truck hitch assemblies. Specific inner diameter and width are not publicly detailed but conform to OEM standards.
- Quality Assurance: Manufactured in ISO 9001-certified facilities to meet or exceed US OEM specifications.
Benefits
- Enhanced Durability: High-strength steel and corrosion-resistant coating ensure exceptional load capacity and wear resistance, extending service life in rugged construction and hauling environments.
- Reliable Performance: Self-aligning design adjusts to misalignments, reducing friction and enhancing hitch performance, improving machine efficiency, and minimizing maintenance needs.
- Cost-Effective: Offers a high-quality aftermarket or OEM alternative, lowering maintenance costs compared to replacing entire hitch assemblies. No core charge required.
- Improved Operation: Enhances smoothness of hitch operation under heavy loads, extending the lifespan of oscillating hitch systems.
