| Machine Series | Compatible Models | Application |
|---|---|---|
| Graco SaniForce™ Pump Systems | 25C411, 25C412, 25C413, 25C414 | Sanitary fluid transfer & industrial pumping |
| Graco OEM Fluid Section Assemblies | Drive shaft assemblies using ref. parts 17P620–17P644 series | High-flow and low-pressure pump systems |
| Graco Sanitary Processing Equipment | Equipment using 17P643 bearing stack configuration | Food-grade & sanitary fluid handling |
The Graco 17P643 Bearing is a precision OEM component designed for use within Graco’s sanitary and industrial pump assemblies, particularly in the SaniForce™ fluid handling systems. It functions as a key rotational support element within the drive shaft assembly, helping reduce friction and maintain smooth mechanical motion under continuous operation.
In the pump stack, the 17P643 BEARING works alongside components such as the 17P620 COUPLING, 17P644 SPACER, and 17P628 SEAL (PTFE), ensuring proper alignment and durability of the rotating shaft. According to Graco’s official parts breakdown, two bearings are typically used per assembly, indicating its critical role in load distribution and operational stability.
Manufactured to OEM tolerances, this bearing is engineered for chemical resistance, sanitary compliance, and long service life in demanding pumping environments such as food processing, pharmaceuticals, and industrial fluid transfer systems.
