The Bearing cage LM Guide SHW (รังลูกปืน LM Guide SHW, which is the term in Thai) is a component of the bearing that travels alongside the rolling parts it surrounds. It primarily serves to separate the rolling parts and typically holds them in the bearing while guiding them.
The Bearing Cage’s Purpose
· The Cage’s Function In Real-World Applications
The speed limit of a stamping cage has been approximately 6000r/min, and the brass cage has a maximum limit speed of roughly 2500r/min.
Keep the impact of frame precision on peeling from bearing fatigue. The rolling components and the cage generate substantial friction when the cast iron cage is deformed. The friction increases the rolling elements’ surface area and decreases their hardness, which causes them to peel off under heavy pressure. Cage structure’s impact on life span would be due to the various cage structures. Roller bearings spherical in shape have a distinct temperature rise when operating at high speeds.
· The Bearing Cage’s Material
When a rolling bearing is in use, heat, and wear are caused by the friction of sliding. Inertial centrifugal force exacerbates heat, wear, and friction, especially in high-temperature working situations. In extreme circumstances, it will result in the cage burning or breaking, which will prevent the bearing from functioning correctly. As a result, the cage’s material must possess a particular level of strength as well as high thermal conductivity, low wear and friction, great impact low density, toughness, and a linear coefficient expansion that is close to that of the rolling element. Additionally, the material must have strong processing qualities and the stamping cage must be able to tolerate more complex stamping deformation. Some exceedingly difficult cages still have a covering of silver on them. Low carbon steel and stainless steel cages, bakelite/plastic (nylon) cages, brass/bronze/aluminum alloy cages, and other types of cages are available.
· Die-Casting Cage
Brass and aluminum alloys serve as the die-casting cage’s primary raw materials. The cage is die-cast in one step after the raw materials have been melted and placed into the die-casting mold of the machine. Rest assured that the casting gate would be rotated on the lathe.
· Cast-Safe Plastic Cage
Use a barrel to gather granular engineering plastics that have been vacuum-dried. Heat it along with a resistance wire and melt it into a semi-liquid condition, pressurize it with a plunger or moving screw to let the raw material in a semi-liquid state injected into the insulating mold from the nozzle of the injection molding machine, Once cooled, get the needed cage.
