Main Function: To support the pump shaft, bear radial and axial loads, and ensure stability and alignment when the impeller rotates at high speed.
Structural Features
Typically uses heavy-duty single-row or double-row tapered roller bearings to adapt to the high-load, high-vibration working environment of slurry pumps.
Most are designed for grease lubrication, while some high-end or high-power models use an oil lubrication system.
Bearing assemblies often come with sealing devices (such as gland seals or sealing rings) to prevent slurry ingress and grease leakage.
Installation Form: Commonly a cylindrical structure, which facilitates overall disassembly and adjustment of the impeller clearance.
Operating Temperature Limit: Under normal operation, bearing temperature generally does not exceed 60–65°C, with a maximum of 75°C.
In short, slurry pump bearings are the core supporting components that ensure reliable shaft rotation and prolong equipment life. Their selection and maintenance directly affect the overall operational efficiency and stability of the machine.
