Product Overview
This bearing block is manufactured from HT300 high-strength cast iron through integral casting and precision CNC machining. It offers exceptional structural strength with a compressive strength of 300MPa, providing 25% higher anti-deformation capacity than standard cast iron bearing blocks. The unit can stably withstand radial loads up to 20kN and axial loads up to 8kN during high-speed operation.
Key Features
- Material: HT300 high-strength cast iron (optional cast steel, ductile iron)
- Machining precision: Bearing hole IT5 grade, fit clearance ≤0.005mm
- Anti-rust treatment: Phosphating + painting, passes 72-hour salt spray test
- Load capacity: Max radial 20kN, max axial 8kN
- Compatibility: Suitable for deep groove ball bearings, cylindrical roller bearings

Applications
This bearing block is widely used in rotating machinery applications. In CNC machine tool spindle systems, it ensures stable operation at speeds up to 8000r/min. It supports 15kW-110kW motor transmission equipment and performs reliably in conveying machinery like belt and chain conveyors. The unit is also suitable for construction machinery such as cranes and excavators, as well as drive shaft support in printing and textile machinery.
Customization Options
We offer comprehensive customization services to meet specific requirements. Customization options include bearing hole diameters (φ10mm-φ200mm), base lengths (50mm-500mm), material selection (45# cast steel or QT500 ductile iron), and various surface treatments (galvanizing, chrome plating, or sandblasted matte). Structural modifications such as double bearing hole design, oil filling holes, or sealing grooves are also available. Sample proofing cycle is 3-5 days with 100% quality inspection during mass production.
