6E-4373 51 mm OD Compression Spring
Cat® compression spring used in rotary pumps, 51 mm OD
Description
The compression spring is used to support the drive shaft within the rotary pump cylinder assembly and ensure proper pump operation. It has a helical shape and consists of tightly wound coils with gaps between the coils. This structure allows the spring to compress and extend under axial load, exerting a force that resists compression.
Features
- Withstands the … on the component
High loads and vibration• Features high strength and high wear resistance
Applications
The compression spring is used to provide the restoring force necessary for the drive shaft to ensure proper operation of the rotary pump.
