Product Description
JDB inner diameter 25mm series 25*30*30 oil free bearing Self lubricating copper bushing
Product Description
JDB bronze inlaid bearing is a solid lubricating product with 6-6-3W copper as the matrix, embedded with graphite and MoS as the solid lubricant. Due to the higher density of 6-6-3 copper than high-strength brass, it is very wear-resistant in high-temperature and low-load situations. It has been used in fireplace doors, oven runners, rubber machinery, light industry machinery, and machine tool industries. Wait for low load, high temperature and medium speed.
Advantages of bearing
1. The design is flexible, simple and convenient, with a wide range of use:
The mechanical design of the oil supply system is a time-consuming and time-consuming device. The use of solid lubricating bearings does not require the consideration of oiling devices in the design, saving the oiling device equipment. At the same time, it can be designed for various special occasions. Various shapes to meet the needs of various special occasions, the use of solid lubricating bearings can greatly reduce the cost of mechanical maintenance, oil, etc.
2. No oil can be used Since the linear expansion coefficient of the solid lubricant is greater than that of the metal matrix, when the solid lubricating bearing starts to operate, the oil film will be transferred to the abrasive parts to achieve
self-lubrication, so the solid lubricating bearing can be used in places where it is difficult to add oil or oil or grease. , Even
in the case of low speed and high load, it also plays a good role in lubrication.
