Core positioning:This product is specifically designed for use in plastic crushing and washing lines.Crusher (often referring to shredder or fine crusher) main shaftThe high-performance bearing support unit is designed to withstand not only enormous radial and axial impact loads, but also...High humidity, high dust content, and contains corrosive impuritiesIn extreme environments, providing absolutely reliable sealing and lubrication protection for precision bearings is a key fundamental component that determines the continuous uptime and service life of equipment.
In the harsh environment of a plastic crushing and washing line, the bearing housing is one of the components that bears the most complex combined stress:
Extreme load impact:When breaking irregular hard materials or encountering uncrushable objects, the main bearing is subjected to strong forces.Impact and fluctuation loadsThe requirements for the rigidity and fatigue resistance of the bearing housing are extremely high.
Water invasion (core threat):Equipment washing, humid environment, and direct water spray conditions makeWaterproof sealThis becomes a top priority. Once water gets in, the grease emulsifies, and the bearing fails rapidly.
Penetration of dust and fine particles:Plastic powder, mud, and fine fiber debris can easily penetrate the bearing cavity, causing abrasive wear and damaging the bearing raceway.
Corrosive environment:Recycling plastics may contain residual chemicals, and the components of the recycled water itself may corrode metal parts.
Traditional or poorly designed bearing housingsThis will result in:
Seal failure:Water and dust entered the bearings in a short period of time, causing them to burn out frequently ("seize up").
Structural cracking or deformation:Under prolonged impact, the housing may develop cracks or the mounting holes may deform, leading to loss of spindle alignment and causing vibration and cascading damage.
Maintenance difficulties:Replacing a bearing requires complete disassembly, which is time-consuming and labor-intensive.
We adopt"Heavy-duty structure + multiple seals + long-lasting lubrication + convenient maintenance"Integrated design concept.
1. Robust heavy-duty structural design:
High-strength materials:useQT450-10 Ductile IronorZG270-500 Cast SteelIt possesses excellent tensile strength, toughness, and shock absorption properties, far exceeding those of ordinary gray cast iron.
Optimization of rib layout:The layout of the box girder reinforcement was optimized through finite element analysis (FEA), and the key stress-bearing parts were strengthened to achieve [the desired effect].High rigidity, lightweight, and deformation resistant。
Precision machining benchmark:The bearing mounting holes, end cap stops, and base planes are all machined with high precision in a single clamping operation, ensuring...Extremely high coaxiality and perpendicularityThis ensures the rotational accuracy of the spindle system.
2. Revolutionary multi-sealing system (core advantage):
