Spherical plain bearings - Radial spherical plain bearings Ingestion-build-111333 The surface insulation resistance (SIR)

The surface insulation resistance (SIR) ensures the resistance stability by applying an electrical bias across an interdigitated comb in a damp heat environment at elevated temperatures

The equipment is designed to incorporate protective filters

Tolerances on wall thickness of solid and hollow profiles

which specifies signals and media

minimum proof strength values

Spherical plain bearings - Radial spherical plain bearings Ingestion-build-111333 The surface insulation resistance (SIR)1 Scope This part of ISO 12240 specifies dimension series, tolerances and radial internal clearances for radial spherical plain bearings. The dimensions and tolerances specified in this part of ISO 12240 have been selected to permit the design of radial spherical plain bearings using a wide choice of sliding material combinations. The specified tolerance values apply to finished, radial spherical plain bearings before any coating, plating, ring
