Introduction
features tapered roller bearing is composed of solid inner and outer rings with tapered raceway and tapered roller components with window cage. bearing forms are: ■ standard design ■ matching open variant design integrated design of single side seal, JK0S . open bearing is separable bearing. Therefore, the inner and outer rings with roller and cage assembly can be installed separately. provides metric and British bearings. The bearing with the letter k in the model is an English bearing. in the new design, please give priority to Metric tapered roller bearing. t7fc series tapered roller bearings belong to the design of X-life . The surface quality of these bearings has been further improved, and higher performance has been achieved through better materials, heat treatment and optimized contact geometry. This improves the friction characteristics and improves the basic dynamic load rating. under the same working conditions, the basic rated life of the bearing is significantly improved. This means that more compact bearing arrangements can be used in some applications. X-life please refer to the size table for bearings. tapered roller bearing can bear single direction axial load and high radial load. generally, two tapered roller bearings are used in symmetrical arrangement. bearing is of type o or x . Please refer to page 520 and figure 1 and figure 2 . the axial bearing capacity depends on the contact angle, that is, the larger the contact angle is, the greater the axial load the bearing can bear. the coefficient in the size table e indicates the size of bearing contact angle and bearing capacity. 313 , 323.. - B , t5ed and t7fc series bearings have large contact angle, so they have high axial bearing capacity. the improved contact line between the tapered roller and the inner and outer raceways optimizes the stress distribution at the contact point, prevents the generation of edge stress and allows the bearing not to center compensation. load ratio P / C R & le; 0.2 , the relative inclination angle of the bearing inner and outer rings cannot exceed 4 & prime;. if you need to bear more load or more tilt angle, please contact us. tapered roller bearing with suffix n11ca is a pair bearing of x type, which can bear large bidirectional axial load and moment load. the internal axial clearance of the matched bearing is set by the spacer between the two outer rings and expressed in the suffix, see page 529 . according to customer needs, we also provide o type matching bearing (n11cb) . when ordering bearings, you must specify the number of bearings, not the number of bearing pairs. tapered roller bearing JK0S is a one-sided sealed ready to install ready to use unit, mainly used for o layout
