consisting of a solid, spherical O.D. inner ring and a spherical I.D. outer ring. The outer ring has a single fracture to permit assembly. Both inner and outer rings are phosphate treated and then coated with molybdenum disulphide (MoS2). Bearings 16FS30 through 60FS90 are available with reinforced rubber seals. To order, add suffix “TT” to bearing designation Example: 16FS30-TT. Bearings 70FS105 through 300FS430 are available with synthetic resin seals. To order, add suffix “SS” to bearing designation - Example: 70FS105-SS. Before ordering any bearing, check for availability. Type FS bearings are a metric series which follows proposed International Standards Organization (ISO) standards. MetricInch conversions given are for the convenience of the user. The controlling dimensions are in millimeters.
2 on page B423. Dimensions listed are before coating with molybdenum disulphide. The axial internal clearance is approximately three times the radial internal clearance. α is the maximum tilting angle for sealed radial bearings. To utilize the maximum tilting angle for unsealed radial bearings the suggested shaft shoulder diameter da1 shown in the drawing on facing page must not be exceeded. Dimensions and locations of lubrication holes and grooves may be obtained from your Timken representative.
