FB09G rolled inlaid bearing
Both FB09G rolled inlaid bearing and JDB-650 sleeve are self-lubricating bearings, but they differ in material, structure and application.
FB09G rolled inlaid bearings are usually rolled with CuSn8 bronze as the base material, with high load capacity and good wear resistance. The working surface of this bearing is usually covered with regular diamond-shaped oil holes or oil holes for storing grease to achieve better lubrication. They are mainly used in high-load and low-speed occasions such as agricultural machinery, forest machinery, and construction machinery. In terms of technical parameters, the density of FB09G bearings is 8.9g/cm³, the compressive strength is 470N/mm², the thermal conductivity is 58W/m.k, the linear expansion coefficient is 18.5x10^-6/K, the hardness is between 90 and 120 HB, and the elongation is 55% 4.
JDB-650 bushing is a copper-based solid inlaid self-lubricating bearing, whose base material is copper alloy (ZCuZn24Al6), with good wear resistance and self-lubricating properties. JDB-650 bearings are suitable for high-load, intermittent or swinging motions, such as automobile production lines, turbines, reservoir working/accident doors, plastic machinery, etc. Its main technical parameters include maximum load of 250N/m², operating temperature range of -100℃ to 300℃, maximum linear speed of 2m/s (grease lubrication) at low speed, maximum PV value of 1.65N/m㎡.m/s, tensile strength of 750N/m㎡, hardness HB>=210, and elongation of 12% 1 2 .
In general, FB09G rolled inlaid bearings are suitable for high-load and low-speed occasions, while JDB-650 bushings are suitable for high-load and good wear resistance and self-lubricating properties. The two are different in materials, structural design and application areas, so the selection should be determined according to specific usage conditions and requirements.
Since specific models (such as FB09G) may be produced by specific manufacturers, it is recommended to directly contact relevant bearing manufacturers or authorized dealers, such as Zhejiang Mingxu Machinery Manufacturing Co., Ltd., to obtain detailed product specifications, prices and purchase information. These companies can usually provide detailed product catalogs, technical consultation and support.
