PIB are manufacturers of precision ball bearings. Their R Series type is a single row, inch series with sizes from 1/8 inch to 1 inch. They can be ordered in stainless steel, flanged, shielded or sealed for high speed applications. PIB's 6000 Series type are deep groove radial ball bearings, single row, made of steel, for axial or radial loads operating at high speeds. Shaft sizes are relatively large, with deep honed raceways.  They are available in open, sealed or shielded configurations. PIB's 6800 Series type feature a large outside diameter, and may be obtained with light, standard or heavy torque. Their Felt Seals Series are a light duty, single row radial type with high quality felt seals, precision ground raceways and steel balls. Their Thin Section Series type offers precision tolerances and high temperature ratings. PIB also offers double row bearings.

RBC are suppliers and manufacturers of ball bearings for industrial and aerospace applications. Types include Nice, radial, heavy duty needle roller, Fiberglide self lubricating, spherical plain, tapered roller, and stud type track roller designs. Nice ball bearings come in standard inch type, radial, angular contact or thrust type, and come with flanged housings in sealed, shielded or open configurations. Nice ball bearings are  ground, semi-ground, heavy duty precision, single row unground and unground thrust, radial or flanged radial designs. RBC radial ball bearings are standard type or Conrad type in sealed and unsealed designs.

Shanghai Unite Technology are manufacturers of ceramic ball bearings in various ceramic materials. Types available include deep groove, thin section, double wall and self aligning. Deep groove ball bearings are precision grade ABEC 1 or ABEC 5, available in metric or inch type. Configurations include open, sealed or shielded type with steel, nylon, PTFE, PEEK or bronze retainers. Ceramic bearings can be used at high temperatures and poor lubrication conditions, as they are self lubricating. However, full ceramic bearings are not suitable for heavy loading.
