Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Rotor Bearing
Supports the rotor at high speed and heavy load, accommodating misalignment and thermal expansion within the design limits.
Rotor Bearing (Rotor Bearing)— Impact Crusher Wear part, position 07.
Location and Function
| Material Options | Clean 100Cr6/SAE 52100 bearing steel; cage and rolling elements to the manufacturer's design |
| Typical Properties and Acceptance Criteria | Bearing raceways commonly have a hardness around 58–64 HRC. Impact crushers often use double-row spherical roller bearings, but the designation, clearance and cage vary by machine. Verify dynamic and static load ratings, limiting speed, C3/C4 internal clearance, fits, grease, permitted temperature and contamination control. External dimensions alone are insufficient for selecting a replacement that meets the required bearing life. |
| 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.
