Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Pinion Shaft Bearing
Supports the pinionshaft and maintains gear pair centre distance and meshing accuracy.
Pinion Shaft Bearing (Pinionshaft Bearings)— Gyratory Crusher Wear part, position 28.
Location and Function
| Material Options | Clean 100Cr6/SAE 52100 bearing steel and OEM-specified cage and rolling element materials |
| Typical Properties and Acceptance Criteria | Bearing rings and rolling elements generally require uniform hardening to around 58–64 HRC, clean steel and controlled residual stresses. Acceptance and maintenance checks also cover internal clearance or preload, fits, circular runout, lubrication, temperature, vibration and metallic debris. Bearing clearance directly affects the gear contact pattern. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; gear tooth or pin-and-bushing wear, pitting, scuffing, uneven loading and fatigue; 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.
