Types AXNA, AXNB and ARNB combined bearings and their derivatives consist of a needle bearing with or without a cage, with a high radial thickness, each face of which acts as a raceway for a needle or roller thrust bearing. The inner ring, secured laterally between the thrust plates, acts as the inner radial raceway.
These bearings which take up very little space, are particularly recommended for shafts requiring very precise axial positioning, operating under load, such as leading spindles, ball-screws for numerically-controlled machine tools, drive shafts on control apparatus, etc.

Seal carrier assemblies DRS are screwed to the centre washer of needle roller/axial cylindrical roller bearings and precisely centred there. They seal the bearings from the outside. The sealing elements are supplied as a complete set and comprise a seal carrier with an integral rotary shaft seal, a gasket and socket head cap screws for mounting the carrier on the centre washer of the bearing.

CERBEC Balls are made from two types of silicon nitrides made by Saint-Gobain Ceramics: NBD200 and SN101C. Both are qualified by bearing companies worldwide and meet all the essential requirements of a bearing grade silicon nitride. They are both fabricated using glass encapsulation HIPing which assures 100% density, high beta phase content, micron-sized grains, and minimal levels of glass phase. The attached TABLE 1 shows the typical properties for NBD200 and SN101C silicon nitrides.

For bearings, a silicon nitride must have certain important characteristics to work properly – in other words, not just any silicon nitride will meet the requirements of bearing performance. There are relatively few silicon nitride’s on the market that are qualified by bearing companies worldwide. Saint-Gobain makes CERBEC balls from (2) qualified silicon nitrides: NBD-200 and SN-101C which are described below.

440C Stainless Steel Series Balls: A martenistic type steel used extensively in bearing applications that require hardness, dimensional stability, corrosion resistance and toughness. Resistant to fresh water, steam, oil, gas, perspiration, alcohol, blood and food stuff. 440 is also magnetic.
316 Stainless Steel Series Balls: Providing resistance to sulfurous acid compounds and other highly corrosive environments. 316 Stainless Steel is used in the presence of sulfuric, phosphoric and ascetic acids. It is the least magnetic of the 300 series.
304 Stainless Steel Series Balls: An austentistic, unhardened stainless steel with excellent resistance to corrosion by oxidizing agents, most organic checmicals, food stuffs and sterilizing solutions.
302 Stainless Steel Series Balls: Extremely corrosion resistant to oxidizing solutions and organic compounds in an unhardened state. In its annealed condition it withstands attacks by food stuffs, sterilizing solutions and nitric acid. Not recommended for sulfuric or halogen applications, and is slightly magnetic.
52100 Chrome Steel Balls: Contains chromium and has excellent surface quality and high load capability due to thorough hardening. 52100 Chrome Steel is a universal material for many applications.
