The important data of the spherical roller bearings have this a few kinds

Wafangdian bearing authors for you on June 21, the important data of the spherical roller bearings have the several: as an integral part of large mechanical equipment operation, bearing is a kind of high precision parts and components, high added value is now bearing a few data to carry on the simple introduction. Internal radial clearance: internal radial clearance refers to the inner ring of bearing clearance before installation. Its size in the radial direction with the inner ring relative outer ring from a limit position to another extreme position to determine the displacement. Working clearance, clearance after the installation is running clearance of the bearing under the condition of normal temperature. Its size is refers to the shaft in the radial direction position of from one extreme to another extreme position displacement. Work clearance from the initial internal radial clearance, and with full coordination and installation condition the influence of temperature change. The important data of the spherical roller bearings have several: the axial clearance: internal axial clearance sa under no load conditions, a bearing ring in the axial direction of the bearing position of from one extreme to another extreme position of displacement. Bearing materials: INA and FAG rolling bearings can satisfy the fatigue strength, wear resistance, hardness, toughness and structure stability requirements. For ring and rolling body is generally low alloy material, high purity of hardening chrome steel. To bear greater impact load and alternating stress of bearing, carburizing steel is also available. In recent years, the improvement of spherical roller bearing steel quality has become a basic rated load bearing the main factors that greatly increased. Research and practice have been confirmed and made of the existing standard bearing steel bearings, the load is not too high and the conditions of lubrication and cleaning suitable cases, can achieve its fatigue limit bearing comfortable and durable, )
