Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing` s working surface will influent the operating noise. Naimei Bearing adopts precision CNC machining to dimension precision, geometric tolerances, design drawing, mold making, grinding, cleaning, assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.
Balls: The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing`s load tolerance and operating capability. We use high precision, small vibration steel ball. It`s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.
Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls` movement and to improve lubrication performance inside the bearing., etc. Naimei Bearing`s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.
Seal: Naimei Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.

Applications:
Water chiller used in plastic processing machinery mold cooling,
Can greatly improve the surface finish of plastic products, reduce surface marks and internal stress, the product does not shrink, without distortion to facilitate stripping of plastic products, accelerate product shape, thus greatly improve the production efficiency of plastic molding machines; Chiller used in CNC machine tools, jig boring machines, grinding machines, machining centers, machine tool and a variety of precision machine tool spindle lubrication and hydraulic cooling system transmission media can precisely control the oil, effectively reduce the thermal deformation of the machine, to improve the machining accuracy.
Extruder
Extruded pipe, trunking, cable and all kinds of plastic profiles.
Heated to melt molding raw material through a cold water bath after cooling, cold water tub water temperature must be kept constant.
As the production of high speed, high cooling capacity required due to surface units.
As already frozen pond if large enough, the unit may not deserve the tank.
Bottle blowing machine
Mainly produce various kinds of mineral water bottles, soda bottles.
Compressed air drying - Blow required clean, dry compressed air, the use of industrial chillers provide chilled water for cooling the compressed air source can remove moisture.
Mold cooling - Chiller can accurately control the mold temperature, improve product quality, increase production efficiency. Compressed air drying and can use the same mold cooling chiller for cold source
Thermoformed
The most common products for a number of small containers, such as yogurt cups
Plastic is heated at a constant frequency extrusion die to maintain a constant temperature is very important for the chilled water temperature range is very high, requiring a proportional valve from the cold water, but to precisely adjust the temperature.
Function:
Refrigerant: R22/R407c/R134, client can choose the refrigerant/gas.
1. Adopt the advanced scroll compressor, resistance low temp and high efficiency
