Silicon nitride or Si3N4 bearings provide some of the best benefits out of all UNASIS brand ceramic bearings. Due to recent developments in manufacturing capabilities, the precision and material quality of silicon nitride bearings has drastically improved. Silicon nitride is only about 40% the weight of the bearing steel equivalent which provides significant weight saving benefits.
As silicon nitride bearings do not require lubrication in combination with the hard running surface, there is very smooth and low torque operation. Although, the noise rating is higher when compared to a steel or hybrid bearing.
Just like other ceramic bearings, silicon nitride bearings are non-magnetic, non-conductive, corrosion resistant and clean room approved.
Many popular sizes are available from stock at Carter Bearings while other arrangements can be easily customized at competitive delivery times. Deep groove ball bearings, angular contact, needle, roller and self-aligning bearings can all be requested. Custom silicon nitride bearings are also an option so please reach out with your particular requirements.
