Product Introduction: Bearing-Spherical Roller 159-3945 for Caterpillar Equipment
Overview
The Bearing-Spherical Roller 159-3945 is a precision-engineered component designed for Caterpillar equipment, specifically used to accommodate radial and axial loads while allowing for misalignment in heavy-duty applications, such as transmission or final drive systems. This spherical roller bearing is critical for ensuring smooth operation and durability in demanding environments, primarily articulated trucks and wheel loaders. 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-grade, hardened steel, designed to withstand high radial and axial loads, resist wear, and perform reliably in harsh operating conditions. Features precision-machined inner and outer races with self-aligning rollers for optimal load distribution and misalignment compensation.
- Design: Precision-engineered spherical roller bearing, built to OEM specifications for precise fitment and performance. Optimized for high-stress environments, such as transmission or final drive assemblies, with sealed or lubricated options for low maintenance and extended service life.
- Compatibility: Compatible with Caterpillar equipment, specifically:
- Articulated Trucks: 725, 730, 735, 740, 740B, 740C, D250E, D250E II, D300E, D300E II, D350E, D350E II, D400E, D400E II.
- Wheel Loaders: 950G, 950G II, 962G, 962G II, 966G, 966G II, 972G, 972G II. Typically used in transmission or final drive systems to support rotating components. 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: Specific dimensions are not publicly detailed but conform to OEM standards for the listed models, ensuring a precise fit. Typical spherical roller bearings for articulated trucks and loaders have inner diameters of 2-5 inches, outer diameters of 4-8 inches, and widths of 1-3 inches.
- Quality Assurance: Manufactured in ISO 9001-certified facilities to meet or exceed US OEM specifications.
Benefits
- Enhanced Durability: Hardened steel construction ensures exceptional strength and wear resistance, extending service life in rugged construction and hauling environments.
- Reliable Performance: Accommodates misalignment and heavy loads, enabling smooth operation in transmission or final drive systems, enhancing machine efficiency, and reducing maintenance requirements.
- Cost-Effective: Offers a high-quality aftermarket or OEM alternative, lowering maintenance costs compared to replacing entire assemblies. No core charge required.
- Ease of Installation: Engineered as a direct-fit replacement, streamlining the repair process and minimizing downtime.
Applications
The Bearing-Spherical Roller 159-3945 is designed for use in Caterpillar equipment, specifically suited for:
- Articulated Trucks: 725, 730, 740, D300E, for material hauling and dump operations.
- Wheel Loaders: 950G, 966G, 972G, for heavy-duty material handling tasks.
- Industries: Construction, mining, quarrying, and infrastructure development, where Caterpillar articulated trucks and loaders operate under high-load conditions.
