Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Rotor Bearing Seal
Keeps dust and water out of the bearing while retaining lubricant and allowing contaminated grease to purge.
Rotor Bearing Seal (Bearing Seal)— Hammer Crusher Wear part, position 10.
Location and Function
| Material Options | Metal labyrinth/Taconite arrangement with NBR, HNBR, FKM, V-ring or OEM-specified composite seals |
| Typical Properties and Acceptance Criteria | Heavy dust environments call for multi-stage labyrinths and controlled grease purging. Specify elastomer hardness, tensile and tear properties, and compression set for temperature, grease and fluid compatibility. Metal labyrinth parts require controlled coaxiality, runout, seal clearances and surface finish. Bearing clearance, journal grooves and incorrect greasing can greatly shorten seal life. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; contact fatigue, lubricant contamination, overheating, seizure and seal failure; wear, ageing, extrusion, fluid incompatibility and leakage |
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.
