Bearing Housing

Houses the bearings, seals and lubrication system and transfers rotor loads to the frame.

Bearing Housing

Bearing Housing (Bearing Housing)— Impact Crusher Wear part, position 18.

Installation and Function

Installation PositionAt both ends of the rotor mainshaft, outside the frame, position 18 in common layout B.
Main FunctionHouses the bearings, seals and lubrication system and transfers rotor loads to the frame.
Replacement FrequencyLow replacement frequency; repair or replace for cracks, bore size or roundness outside tolerance, failed split faces, damaged seal grooves or an inability to maintain coaxiality.

Materials and Mechanical Properties

ItemDetails
Material OptionsDuctile iron such as EN-GJS-500-7, cast steel or a fabricated steel structure, according to the OEM design
Typical Properties and Acceptance CriteriaBearing 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 MechanismContact fatigue, lubricant contamination, temperature rise, seizure and seal failure

Material and Design Considerations

  • Identify material hardness, particle size, abrasiveness, moisture, temperature, pH, impact and tramp material;
  • High hardness does not replace core toughness, fatigue strength, corrosion resistance or high-temperature performance;
  • For composite, hardfaced, ceramic and elastomer designs, assess substrate bonding, edge protection, fastening and maintainability;
  • For parts that mate with shafts, gears, seals, roll surfaces or housings, control fits, tolerances, surface finish and assembly clearances together;
  • Assess material upgrades using cumulative throughput, dimensional wear, failure modes, product quality and downtime costs.

Required Ordering / RFQ Information

  • Equipment manufacturer, machine model, serial number, part number 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.
