Bracket
OEM Part Numbers Compatible: MM0244567
Bracket
Suitable Model
C100
Application
Main structural load-bearing component of the jaw crusher, withstanding high crushing forces and vibration loads during operation to ensure overall rigidity and operational stability.
Installation Notes
1. Before installation, verify the dimensions of mounting and mating surfaces; remove burrs, rust and debris; 2. Use proper lifting tools when positioning, avoid impact on joint surfaces, and align dowel pins and locating faces as marked; 3. Tighten bolts uniformly in 2-3 symmetrical passes to the designed torque, and re-check levelness and concentricity to meet assembly requirements.
FAQ
How to determine whether the frame can continue to be used if cracks are found?
First stop the machine and clean the crack surface; use dye penetrant or magnetic particle inspection to confirm the crack direction and length. If the crack does not extend to the main load-bearing rib plate and is short, it can be repaired by welding per procedure. If it penetrates the main load-bearing zone or deformation exceeds limits, the frame must be replaced.
What are the common causes of excessive temperature rise in the bearing housing?
Common causes include: insufficient or deteriorated lubricating oil, improper bearing clearance, excessive bearing housing concentricity deviation, seal failure allowing dust ingress, and poor cooling water flow. Check lubrication status, assembly precision and the cooling system item by item.
What causes abnormally large swing of the moving jaw (pitman)?
Usually caused by excessive wear clearance in eccentric shaft bearings, worn moving jaw bearing bushings, insufficient tie rod spring tension, or worn toggle plate and toggle plate seat. Measure each fit clearance and replace parts exceeding the limit.
