6874525 Rolls-Royce (Allison) Bearing | Used / As Removed

The Rolls-Royce (Allison) Bearing 6874525 is a used, as removed turbine engine component designed to support smooth rotation and load distribution.

The 6874525 Rolls-Royce (Allison) Bearing is a precision aerospace engine component designed to support rotating shafts and assemblies within turbine engine systems. Offered in used / as removed condition, this bearing has been previously installed and removed from service and is suitable for inspection, evaluation, and potential reuse in accordance with applicable maintenance and regulatory requirements.

Bearings play a critical role in turbine engines by reducing friction, supporting radial and axial loads, and maintaining precise alignment of rotating components. Proper bearing performance is essential for smooth engine operation, vibration control, and protection of adjacent engine hardware. Any degradation in bearing condition can directly affect engine efficiency, reliability, and service life.

Part number 6874525 is manufactured to exact aerospace specifications to ensure correct fitment and compatibility with approved Allison engine configurations. Bearings of this type are engineered to operate under high rotational speeds, continuous loads, temperature variation, and vibration commonly encountered in turbine engine environments. Material quality, surface finish, and dimensional accuracy are key factors in maintaining predictable performance.

This bearing is associated with turbine engine platforms produced by Rolls‑Royce, including Allison engines widely used in helicopter and fixed-wing aircraft. During maintenance and overhaul activities, bearings are routinely inspected for wear, spalling, scoring, corrosion, or heat distress that may affect serviceability.

As an as removed component, this bearing is well suited for MRO facilities, repair stations, and operators managing repairable inventory, overhaul cores, or exchange programs. Final determination of airworthiness, including inspection, testing, and certification, must be completed by qualified aviation maintenance personnel prior to installation.

Installation and approval for return to service should always follow the applicable engine maintenance manuals and regulatory standards. Proper handling, cleaning, and inspection are essential to ensure bearing integrity and prevent contamination.

The Rolls-Royce (Allison) Bearing P/N 6874525 remains an important engine support component, contributing to reliable power transmission and smooth operation in demanding aerospace applications.
