NKE produce small and medium sized deep groove ball bearings, including thin section bearings in stainless steel. These bearings have rings and balls made from high - chromium alloy stainless steel. The cage material for bearings with pressed cages is also stainless steel. The NKE stainless steel bearings feature similar load ratings as the standard bearings made from normal bearing steel. NKE Stainless steel bearings are resistant to humidity, water, steam and many alkaline solutions. The resistance to acids, however, is limited. It is dependant upon the individual operating conditions (i.e. acid concentration and its temperature). In some applications, using sealed stainless steel bearings also the resistance of the lubricant used and the seal material must be considered. NKE stainless steel deep groove ball bearings are standard open design. Sealed (suffixes RS or .2RS) or Shield versions [suffix Z or .2Z) are also produced to order request. NKE stainless steel deep groove ball bearings are produced to normal tolerance class (PN) as standard. The dimensional tolerance values are listed in the chapter ..Bearing data / Tolerances. NKE stainless steel deep groove ball bearings are fitted with pressed stainless steel cages as standard. There are several bearing types, cage designs and materials available on request. The NKE range of stainless steel deep groove ball bearings are produced with normal internal clearance (CN) as standard. Other internal clearance groups may be produced upon request (i.e. C2 or C3 etc). The values of internal clearance groups are as for standard deep groove ball bearings according to DIN 620/part 4 and ISO 5753-1981, respectively. NKE - Stainless Steel Deep groove ball bearings are identified by a prefix "SS" (SS stands for , "Stainless Steel"). Example:SS 6205.2RSR
