Product Introduction: Bearing-Self Aligning 8G4189 for Caterpillar Equipment

Overview

The Bearing-Self Aligning 8G4189 is a precision-engineered component designed for Caterpillar equipment, specifically used to support rotational movement while accommodating misalignment in linkage or hydraulic systems, such as articulation or steering assemblies. This self-aligning bearing 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-grade steel with a hardened inner and outer race, designed to withstand high radial and axial loads, resist wear, and perform reliably in harsh operating conditions. Features a self-aligning mechanism to compensate for angular misalignment.
  • Design: Precision-engineered self-aligning ball or roller bearing, featuring two rows of rolling elements (balls or rollers) and a spherical outer raceway, allowing for misalignment correction. Engineered to OEM specifications for precise fitment and performance. Optimized for high-stress environments, such as articulation joints, with sealed or lubricated options for low maintenance.
  • Compatibility: Compatible with Caterpillar equipment, specifically:
    • Articulated Trucks: 725, 725C, 730, 730C, 735, 735B, 740, 740B, D250B, D250D, D250E, D250E II, D300B, D300D, D300E, D300E II, D350E, D350E II, D400, D400D, D400E, D400E II. Typically used in articulation joints or steering assemblies to support rotational movement while accommodating 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: Specific dimensions are not publicly detailed but conform to OEM standards for the listed models, ensuring a precise fit. Typical self-aligning bearings for articulated trucks measure approximately 2-5 inches in diameter, with inner and outer race dimensions tailored to articulation systems.
  • Quality Assurance: Manufactured to meet or exceed US OEM specifications, with quality control conducted in ISO 9001-certified facilities.

Benefits

  • Enhanced Durability: High-grade steel construction ensures exceptional strength and wear resistance, extending service life in rugged construction and hauling environments.
  • Reliable Performance: Self-aligning design accommodates misalignment, reducing stress on components, enabling smooth operation in articulation systems, and minimizing maintenance needs.
  • 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-Self Aligning 8G4189 is designed for use in Caterpillar equipment, specifically suited for:

  • Articulated Trucks: 725, 730, 740, D250E, D400E, for material hauling and dump operations in construction and mining.
  • Industries: Construction, mining, quarrying, and infrastructure development, where Caterpillar articulated trucks are employed for heavy-duty material transport.
