Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Rotor Bearing
Supports the heavily loaded rotor and accommodates misalignment and thermal expansion within the design limits.
Rotor Bearing (Rotor Bearing)— Hammer Crusher Wear part, position 08.
Location and Function
| Material Options | Clean 100Cr6/SAE 52100 bearing steel; cage, rolling elements and surface treatment to the bearing manufacturer's design |
| Typical Properties and Acceptance Criteria | Hammer crushers commonly use heavy-duty spherical roller bearings with raceway hardness around 58–64 HRC. Establish basic rating life, internal clearance, cage, tapered or cylindrical bore, fits, grease and permitted temperature for the load, speed and temperature rise. TerraSource TKK provides an example using self-aligning spherical roller bearings; the exact bearing designation cannot be inferred from appearance. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; contact fatigue, lubricant contamination, overheating, 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.
