Product Description

 

HIP-Si3N4 Bearing Ball With G5 Grade For Ceramic Ball Bearing Of Ø11.113 mm

 

Our silicon nitride ceramic bearing balls are made of highly purified, submicron powder with an alpha phase of more than 92%, and are sintered by HIP (Hot Isostatic Pressure) technology. Our company has more than two production lines specializing in the production of high-precision silicon nitride balls of routine size for ceramic bearings. With our recipe and technology advantages, our hot isostatic pressure sintered silicon nitride ceramic bearings can improve the bearings proerties. And because of the good properties of silicon nitride, bearings fitted with our ceramic balls can have less quality and higher speed.

 

► Key properties of hot isostatic sintered silicon nitride
♦ Max temperature to 1000℃
♦ High strength over a wide temperature range
♦ High fracture toughness: 6.1 MPa-m1/2
♦ High hardness: 1580 HV5
♦ Outstanding wear resistance, both impingement and frictional modes
♦ Good thermal shock resistance
♦ Good chemical stability,resistance to acid and alkali corrosion
♦ Good electric insulation

Our gear pumps used to suffer frequent bearing corrosion & damage in high-temp conditions. Since switching to this customized silicon carbide sliding bearing, we’ve had zero issues!

the precision of the custom sizing is impeccable—it fits perfectly into the pump’s mounting position. The slot and screw details are crafted with great precision, so we could install it directly without any extra adjustments, saving a ton of debugging time.
