Wacker Neuson 5100069250 Cylinder Roller Bearing NJ309ETN1 C3

The Wacker Neuson Cylinder Roller Bearing NJ309ETN1 C3 is a genuine OEM component designed for BPS1550c and BPS2050c series submersible pumps. As a direct OEM replacement, part is manufactured to the exact tolerances required to maintain smooth, efficient pump shaft rotation under the demanding load conditions these machines operate in. This bearing is confirmed to fit both the CE and CN variants across the BPS1550c and BPS2050c model families, making it the correct choice whether you are servicing a unit configured for European or international markets. Order with confidence knowing you are sourcing the factory-authorized component for your Wacker Neuson pump.

Key Features

• OEM-Grade Radial Load Tolerance — Manufactured to the precise internal clearance (C3) specification required for high-speed shaft applications, ensuring the bearing performs within the designed load and thermal range of the pump drivetrain.
• Drop-In Shaft Compatibility — The NJ309ETN1 profile matches the original bearing seat dimensions exactly, allowing straightforward installation without machining or shimming.
• Broad BPS Series Coverage — A single part number covers BPS1550c and BPS2050c models across both CE and CN configurations, simplifying parts procurement for mixed fleets.
• Sustained Pump Shaft Performance — A correctly seated roller bearing keeps shaft runout within spec, preserving impeller alignment and maintaining rated flow output. A worn bearing accelerates shaft wear and can lead to seal failure and motor damage.
• Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, part number 5100069250 carries the full backing of the manufacturer's parts program.

A cylinder roller bearing supports the rotating shaft inside the pump motor housing, carrying the radial loads generated as the impeller spins under hydraulic resistance. The C3 internal clearance designation means the bearing is engineered with slightly greater than standard internal play, which accommodates the thermal expansion that occurs during continuous pump operation and prevents binding. When this bearing wears or loses its clearance specification, vibration increases, seal integrity is compromised, and the motor windings become vulnerable to moisture ingress — making timely replacement critical to the service life of the entire pump assembly.
