Technical Advice
Equipment and part identification, drawing review, material selection and manufacturing feasibility assessment.
Houses the bearings, seals and lubrication system and transfers rotor loads to the frame.
Bearing Housing (Bearing Housing)— Hammer Crusher Wear part, position 09.
| Installation Position | Outside the machine at both ends of the rotor mainshaft; position 09 in the HDS/HUV layout. |
| Main Function | Houses the bearings, seals and lubrication system and transfers rotor loads to the frame. |
| Replacement Frequency | Low replacement frequency; repair or replace for cracks, bore size or roundness outside tolerance, failed split faces or an inability to maintain coaxiality. |
| Item | Details |
|---|---|
| Material Options | Grey iron, ductile iron such as EN-GJS-500-7, cast steel or a fabricated steel structure, according to the OEM design |
| Typical Properties and Acceptance Criteria | Bearing housings must withstand impact and keep both bearings coaxial. Key checks cover material, casting defects and NDT, bearing bore size and roundness, split-face contact, end cover location, seal grooves, lubrication passages and mounting bases. TerraSource TKK provides an example of split cast iron bearing housings with labyrinth seals. Recheck coaxiality at both ends after bore repair. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; contact fatigue, lubricant contamination, overheating, seizure and seal failure |
