Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Bearing Housing
Houses the bearings, seals and lubrication system and transfers rotor loads to the frame.
Bearing Housing (Bearing Housing)— Impact Crusher Wear part, position 18.
Location and Function
| Material Options | 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 keep both bearings coaxial while carrying impact loads. Acceptance checks focus on material, casting defects and NDT, bearing bore roundness and size, split-face contact, end cover location, seal grooves, oil passages and mounting bases. Recheck coaxiality after repairing a bearing bore; measuring its diameter alone is insufficient. |
| Principal Failure Mechanism | Contact fatigue, lubricant contamination, temperature rise, seizure and seal failure |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
