Busch Roller Bearing Part# 473000118 – vacstellar

The Busch Roller Bearing (Part #473000118) uses a specific design for heavy-duty work. Inside its outer shell, it has many small, cylindrical rollers. When the shaft spins, these rollers turn with it.

The big benefit of rollers (compared to ball bearings) is their larger contact area. Think of it like the difference between standing on a single high heel (a ball) versus a flat boot (a roller). The roller spreads the load out more evenly

Bearings are wear items. After thousands of hours of service, they can wear out. Signs include unusual noises (humming, grinding), excessive shaft play, or increased operating temperature. Replacing a failing bearing promptly can prevent catastrophic damage to the shaft and housing.

This Busch bearing is engineered to the exact specifications of your SECO pump. It ensures a perfect fit and restores the pump to its original performance standards.
