The Wacker Neuson Bearing Bracket is a genuine OEM component designed for the AR 52 and AR 53 series pumps, including the AR 52/6/042, AR 53/6/042, AR 52/9/042, AR 53/9/042, AR 52/6/250, AR 53/6/250, AR 53/9/250, and AR 53/3/400 configurations. As a genuine Wacker Neuson part, the is manufactured to the same specifications as the original, ensuring a direct, like-for-like installation with no guesswork. This bracket is a structural support component that plays a critical role in maintaining shaft and bearing alignment within the pump assembly. Sourcing the correct OEM part from the start protects the integrity of the pump and keeps your equipment operating as intended.
Key Features
- OEM-Precision Tolerancing — Manufactured by Wacker Neuson to exact dimensional tolerances, ensuring the bearing seats and mounts align correctly with mating components in the pump housing.
- Direct Drop-In Installation — Engineered to match the original mounting points and bolt pattern of the AR 52 and AR 53 series pump assemblies, slotting in exactly where the factory bracket was positioned.
- Broad AR Series Compatibility — Confirmed fitment across eight AR 52 and AR 53 model variants, including 042, 250, and 400 configurations in both 52 and 53 frame sizes.
- Structural Support for Shaft Integrity — A correctly fitted bearing bracket holds the pump shaft in proper alignment under load; a worn or cracked bracket allows shaft deflection that accelerates bearing wear and can cause pump failure.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100003947 carries the same material grade and quality control as the original production part.
The bearing bracket serves as the structural housing and mounting support for the bearing assembly within the pump. It holds the rotating shaft in precise radial alignment, transferring operational loads into the pump frame while allowing the shaft to spin freely. When the bracket becomes cracked, corroded, or worn, bearing misalignment follows — leading to increased vibration, accelerated bearing failure, and ultimately shaft damage that can take the entire pump out of service.
