The sliding bearings used in automotive air-conditioning compressors require high strength, good wear resistance, and a rather harsh operating environment that makes maintenance difficult. Therefore, the performance requirements for sliding bearings are relatively high.

The company developed a self-lubricating bearing product based on the needs of the market. It uses a high-strength brass alloy ZCuZn25Al6Fe3Me3 as the matrix, together with solid lubricants, high bearing strength, good wear resistance, self-lubricating functions, and maintenance-free advantages. It is very suitable for the harsh working environment of automotive air-conditioner compressors, and it satisfies the demanding requirements of the customers for the performance of the products. The use effect on the automotive air-conditioning compressors is very good.

Hunan Jintai Hardware and Machinery Co., Ltd. is a professional manufacturer of various brands of self-lubricating bearings, graphite copper sheaths and other copper alloy products. The company regularly requests authoritative third-party testing organizations to inspect the company's products to ensure that product quality meets the requirements of national standards.
