Black Silicon Nitride Ceramic Balls 0.8mm to 25.4mm Bearing Ball Precision G5   ● Product Properties : 

Diameter : 0.8mm to 25.4mm

Precision : G5

Colors : Black

Material : Silicon Nitride Ceramic

● Product Features : 

59% lighter than steel ball, greatly reducing the bearing high-speed

and accelerated operation of the groove of the centrifugal force, crushing,

and wear and tear, modulus of elasticity is 44% greater than steel, which means

that the deformation of the force than the steel ball is greatly reduced, the hardness

is higher than steel, HRC reaches 78, the friction coefficient is small, the coefficient of

thermal expansion of steel is 1/4, to withstand drastic changes in temperature, it is easy to

get a high surface finish, Ra can reach 4 ~ 6 nanometers; high temperature resistance: silicon

nitride ceramic ball 1050 ° C high temperature still has high strength, hardness; never rust, can work

without oil lubrication; more resistant to chemical corrosion than steel; metal-free lubrication conditions;

more resistant to chemical corrosion; no metal 6 nanometers, high temperature resistance: silicon nitride

ceramic ball in the 1050 ° C high temperature still has a high strength, hardness, never rust, can be in the

oil-free lubrication conditions of work, more resistant to chemical corrosion than steel, no metal pollution.

Non-magnetic, electrically insulated. There is no adhesive wear.

● Use : 

Silicon nitride ceramic balls can be used in various bearings with

extreme performance requirements: high-speed/ultra-high-speed bearings,

high-precision bearings, vacuum bearings, high/low-temperature bearings,

non-magnetic bearings, high-precision ball screws; they can also be used in chemical pumps,

high-temperature pumps, and metering pumps to be used as valve balls, travel vanes, fixed vanes,

and measuring balls. Silicon nitride ceramic balls are generally assembled into hybrid bearings,

which can be used in high-tech industries such as aerospace, national defense and other industries,

and can also be widely used in other industries such as chemical, metallurgy, medical, food, oil field, electronics and so on.
