Power End Parts
The bearing housing and bearing end cover are core support and sealing components for the power end of mud pumps. Used together, they provide a stable installation space for the bearings while ensuring leak-proof and contamination-resistant protection under high-pressure conditions, making them critical accessories for stable pump shaft operation.
Bearing Housing
Function: The mounting and support housing for bearings, designed to withstand radial loads and ensure shaft alignment.
Features:
Heavy-duty cast steel/cast iron housing with a base mount, offering excellent rigidity and impact resistance.
Stepped internal bearing bore for precise positioning of standard bearings, ensuring stable operation.
Bolt holes on the flange face for easy installation of the bearing end cover.
Advantages: High strength and rigidity, capable of withstanding alternating loads in drilling operations for long-term use without deformation or cracking.
Bearing End Cover
Function: The sealing cover for both ends of the bearing housing, providing both axial positioning for the bearing and dynamic sealing for the shaft.
Features:
Bolt holes on the outer flange for precise alignment and fastening to the bearing housing.
Central internally threaded bore to accommodate the shaft, allowing installation of packing or oil seals to prevent lubricant leakage and ingress of external contaminants.
Anti-corrosion surface coating, offering excellent wear and corrosion resistance for harsh mud pump conditions.
Advantages: Easy installation, reliable sealing, effectively extending the service life of bearings and shafts, and reducing equipment failure rates.
Applications & Compatibility
Compatible with power end bearing assemblies of major mud pump models including F-1300, F-1600, 14-P-220, and 3NB series.
Custom dimensions available based on pump model and shaft diameter requirements, ensuring full interchangeability with original equipment parts.
