HT200 Gray Cast Iron Slurry Pump Bearing Housing – Stable Load-Bearing Core for General Working Conditions

Product Overview: Precise Supporting Component for Slurry Pumps

This product is a dedicated HT200 gray cast iron bearing housing for slurry pumps, serving as the core load-bearing component for pump shaft operation. It is specifically compatible with medium and light-duty slurry pump models such as Jch-Tiktop 6/4-AH(R), and perfectly matches transmission components like the large-diameter DAM073M shaft and 45# steel shaft. Integrally cast from high-quality HT200 gray cast iron, it undergoes precision machining and structural optimization, featuring excellent rigidity, vibration damping performance, and adaptability. Its key functions include fixing bearings, supporting the pump shaft, and distributing radial loads. It effectively complements the short overhang design to reduce shaft deflection and vibration, providing solid protection for the long-term stable operation of slurry pumps under general working conditions.

Core Advantages: Empowered by HT200 Material for General Slurry Conditions

1. Strong Material Adaptability with Stable Load-Bearing Capacity
HT200 gray cast iron has a Brinell hardness of HB180-250, with uniform and dense material, outstanding rigidity, and excellent vibration damping effect. It accurately matches the load requirements of medium and light-duty slurry pumps, effectively distributing radial forces and vibration energy transmitted by the pump shaft, and avoiding component deformation caused by local stress concentration. It complements the high-strength characteristics of the 45# steel shaft, ensuring stable and coordinated operation of the transmission system.

2. Optimized Structural Design for Easy Installation and Maintenance
Cartridge-type integrated structure: Can be quickly fixed to the slurry pump frame with only four through bolts, enabling efficient installation and disassembly, and significantly reducing assembly time;
Built-in lubrication system: Equipped with a dedicated lubrication chamber and oil passages, compatible with both grease and oil lubrication methods, providing a continuous and uniform lubrication environment for bearings, reducing wear, and extending the service life of bearings and shafts;
Dual sealing protection: Fitted with O-rings and skeleton oil seals at both ends, effectively isolating dust and moisture in slurry media, preventing lubricant leakage and corrosion of internal components, and adapting to impurity-rich working conditions.

3. Precision Machining for Excellent Fitting Accuracy
High-precision machining using CNC lathes and grinders ensures key dimensional tolerances are controlled at the micron level. The fitting clearance with the large-diameter DAM073M shaft, 45# steel shaft, and bearings is precisely controlled, reducing component friction and vibration noise during operation, lowering wear loss of the entire pump unit, and improving equipment operation smoothness and overall service life.

4. Cost-Effective Choice for Diverse Scenarios
HT200 gray cast iron features mature production processes and controllable costs, meeting the needs of general working conditions for medium and light-duty slurry pumps while effectively reducing procurement and maintenance costs. It has good machinability and can be make minor adjustments to the dimensions according to different slurry pump models, compatible with assembly requirements of various medium and light-duty slurry pumps. It is suitable for scenarios such as auxiliary mining transportation, municipal sewage treatment, and fluid transportation in the building materials industry under non-strongly corrosive and conventional load conditions.
