2D5173 Bearing As-Roller — Cat 578 594H

This is an assembly bearing, specifically a roller bearing, designed to support heavy loads in applications such as undercarriage or large planetary gear sets. It is manufactured to meet Caterpillar's high standards for durability and performance, providing reliable support and smooth operation compared to a worn bearing with compromised internal components. Operators may notice increased noise, vibration, or difficulty in component movement if this bearing begins to fail.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a failing bearing assembly is often an increase in operational noise, such as grinding or rumbling, and noticeable vibration. If ignored, the bearing's internal components will degrade, leading to increased friction, potential binding of the component, and compromised machine performance. Continued operation risks significant damage to the supported component and surrounding structures.

Installation Tip

Thoroughly clean the bearing housing and the shaft or bore where the bearing will be installed to prevent any contamination. Always use a proper bearing press or installer tool to ensure the bearing is seated evenly and squarely, avoiding any damage to the rollers or races.

Service Note

Inspect the shaft or bore for wear or damage, check seals for integrity, and examine adjacent components for any signs of stress or misalignment.
