Polished Soda Lime Glass Balls for Bearings, Valves, Pumps

EDE-HP series glass balls are made of high-purity soda-lime glass or high-quality borosilicate glass. It has the highest precision, after a special grinding process.The accuracy can reach grade G40, the lot diameter variation is below 2.5um and the roundness tolerance is below 1.25um.The special production process makes it possible to produce the particle size between 1.5-50mm.

EDE-HP serial precise glass balls can be used as valve balls, mixing balls, check balls (sealing balls) and balls in bearings.At the same time, the surface of the glass balls can be classified into polished glass balls, frosted glass balls and colored glass balls according to customer requirements.

Application

Valve– Sealing ball

Its chemical resistance allows it to be used in corrosive media. As a valve ball, glass balls can be used in ink sacs, dispensers in the food and cosmetic industries. The metering pump is usually equipped with EDE-HP serial glass balls.

Ball bearing

Because of its very good corrosion resistance and chemical resistance, it can be used in ball bearings.

Mixing ball

EDE-HP type glass balls are used in the pharmaceutical industry mianly as mixing balls. For example, in order to fully mix the insulin suspension before using it, usually people place the borosilicate glass balls in the insulin refill and shaking, then the insulin concentration in the suspension can be made uniform, so that to give full play to the effectiveness of insulin.

Quality Characteristics

Diameter range of high-precision glass balls: 1.5mm-50mm.

Variation of ball diameter VDws: ≤5um

Lot diameter variation VDwL: ≤10um.

Spherical deviation: ≤5um

Surface roughness Ra≤0.03um.

100% diameter sorting

No bubbles with a diameter over 0.5 mm.Very small number of balls contain bubbles, but the diameter is below 0.5 mm.

Can be in contact with food.
