Recent developments in manufacturing abilities have drastically improved both the precision and material quality of silicon nitride (Si3N4) bearings, and they now provide some of the best benefits of our whole ceramic bearing range.
Similar to other ceramic bearings, silicon nitride is non-conductive, non-magnetic, corrosion-resistant, and clean-room approved. Alongside this, these bearings are only 40% of the weight of their steel equivalents, delivering significant weigh-saving benefits to their applications. They also do not require any lubrication, which combined with the hard running surface creates a very smooth and low torque operation. However, these bearings do deliver a noise rating comparatively higher than those of steel or hybrid bearings.
We can deliver these bearings to you in a variety of popular sizes from stock, as well as offering a customisation services with competitive delivery times. Deep groove ball bearings, angular contact, roller, needle, and self-aligning bearings are all available so please get in touch with our engineers today with your requirements.
