Inch Metric

Metric size range from 0.4 mm to 30 mm

Inch size range from 1/32" to 2 1/2" inch

Some application areas where Silicon Nitride Si3N4 balls are used include.

1) Equipment used in vacuum environment which requires no lubrication or any outgassing.

2) Pillow blocks for bakery ovens

3) Oilfield Sucker rods pumps balls used in valves.

4) Chemical industry

Hot Isostatic Pressing (HIP) Si3N4 balls are also available with lead times of @ 2 weeks. HIP manufacturing process results in increased toughness, increased hardness and less rolling contact fatigue.

Applications include:

Check Valves

Motorsports. Balls are used in Wheel, Clutch and Transmission bearings for lowest possible friction.

Turbomolecular pumps where low lube conditions exist.

Electrical motors where electrical resistance is crucial.
