The ball material is also silicon nitride, which reduces friction and enables higher rotational speeds compared to conventional steel bearings. The design includes a choice of retainers, allowing customisation for specific operational conditions.
Silicon nitride is the standard ceramic for these bearings due to its superior toughness among technical ceramics and its resistance to thermal shock. The retainer can be PTFE for chemical inertness, nylon for general-purpose use, PEEK for high-temperature applications or stainless steel for maximum strength. These bearings are engineered to handle radial and axial loads with minimal wear, even in abrasive or corrosive environments.
Primary applications include aerospace components, automotive turbochargers, medical devices such as dental drills and manufacturing equipment like CNC machine spindles. The bearings are particularly valued in sectors where reliability in extreme temperatures or corrosive conditions is critical. Buyers should confirm packaging specifications and trade terms directly with the supplier.

Before ordering, confirm the exact grade of silicon nitride used, as variations in additives can affect performance. Request documentation on the retainer material’s compatibility with your operating environment, particularly if exposed to chemicals or extreme temperatures.
Discuss lead times, as ceramic components often require extended production periods due to the sintering and finishing processes. Incoterms are typically FOB Kunshan, but verify if the supplier can accommodate CIF to your port. Payment terms may include a 30-50 % deposit, given the specialised nature of the product.
Conduct dimensional inspections using calipers or a CMM to ensure the inner and outer rings meet specified tolerances. Perform a spin test to check for abnormal noise or vibration, which could indicate improper assembly or material defects. Request a copy of the supplier’s quality control plan, including incoming material inspections and final product testing.
