The sorts of cage materials are reduced carbon metal/stainless steel cage, bakelite/plastic, or nylon cage, brass/aluminum/bronze alloy cage, and more.
Die-casting cage:
The raw materials of the die-casting cage are aluminum alloy as well as brass. The raw products are melted and put into the die-casting mold and mildew of the die-casting device, and the cage is die-casted at once. The spreading gate is switched on the lathe. The technical qualities of these parties are:
- The cage is directly created by die casting, which can get a great geometric shape as well as dimensional accuracy, without mechanical processing, and high manufacturing efficiency.
- After die-casting, the metal takes shape and solidifies, the framework is the same, the surface area quality is good, as well as wear-resistant.
- The material application price is high and the cost is reduced.
Nevertheless, when die-casting lightweight aluminum alloy cages, large-tonnage devices are called for, as well as the mold and mildew layout and production are complicated, and the cage pockets are easily damaged during die-casting. Under the condition that the bearing, such as SRG Bearing Set [ชุดตลับลูกปืน SRG, which is the term in Thai], undergoes shock, resonance, as well as speed change, it is required to additional enhance the quality of the die-cast cage.
Plastic casting cage
Put the vacuum-dried granular design plastics in a barrel, heat it with resistance wire to melt into a semi-liquid state, and pressurize with a plunger, or a relocating screw, so that the semi-liquid raw material is infused from the nozzle right into the forming mold of the shot molding machine, and it is insulated, Obtain the needed cage after cooling down. The features of his craft are:
- The cage can be developed by single-shot molding, which can acquire accurate geometric shape, dimensional precision, and reduced surface area roughness worth, without mechanical handling, and high manufacturing effectiveness.
- Mold and plastic casting is easy, the bearing setting up is practical, and automatic control is easy to realize.
- The plastic cage has great buildings such as wear resistance, antimagnetic, and low friction.
