1. The number and types of existing truck bearings are as of 2005; China has a total of 650,000 trucks. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
60t car 62.50; more than 520 million sets of bearings; 197726, SKF197726, 352226X2-2RZ.
70t, 76t, 80t car 25,000 vehicles; 200,000 sets of bearings; Germany FAG, TAROL150R, Sweden SKF, TBU150, the United States TIMKEN, AP150, the United States BRENCO.
2, truck bearing layout mode steel cage 2 million sets; engineering plastic cage 3.1 million sets of non-touch oil seals (laboratory 3 million sets); touch oil seals (SKF197726 and imported bearings 2 million sets) 3, the existing problems ( 1) Many types and types of bearings (21t: five, 25t: five) are not conducive to improving power.
.2) Inconvenient maintenance. Can not be exchanged. The sealing layout is different; the temperature rise is not the same; the infrared warning specifications are 400C and 550C respectively. After the infrared warning, the temperature is raised to distinguish the bearing; in order to determine whether the wheel pair can be replaced. It is extremely inconvenient to use.
.3) Inconvenient to uniform management of bearings. A variety of different types of bearings are not the same as the production and maintenance specifications; especially when the bearing is out of order; the reason for the search is extremely messy.
.4) The limitations of the steel cage due to the manufacturing process; the size of each pocket is large; it affects the rotation function of the bearing; once the seizure is stuck; it is very likely to have a hot axis or a hot-cut axis; the inspector passes the "seven The word "there is no problem with the temperature rise bearing found in the inspection method.
