Self-lubricated Brass Alloy Bushings SPF
SPF
Brass alloy with embedded solid lubricant bushing is to open cavities of appropriate size and orderly arrangement on the metal friction surface of the bushing matrix. It was embedded a molded solid lubricant with unique self-lubricating properties in the cavities (the solid lubricant area is generally 25% - 35% of the friction area) and made of self-lubricating bushings.
It has been used in metallurgy of continuous casting machine, rolling equipment, mining machinery, shipbuilding, gas turbines and other high temperature, high load, low speed heavy load and other occasions.

How can metallurgical equipment suppliers reduce downtime in continuous casting operations?
Continuous casting machines face extreme conditions that cause frequent bearing failures and costly downtime. CS SPF Self-Lubricated Brass Bushings eliminate this vulnerability with their 100 N/mmΒ² load capacity and 300Β°C temperature resistance. Unlike conventional bearings, our embedded solid lubricant technology allows operation without oil for extended periods, dramatically reducing maintenance intervals and preventing unexpected failures in your critical metallurgical processes.
Specifically designed for metallurgical continuous casting machines, rolling equipment, mining machinery, shipbuilding, and gas turbines, the SPF series excels in high temperature, high load, and low-speed applications. The premium CuZn24AL6 brass alloy composition delivers HB230-270 hardness while maintaining a low friction coefficient below 0.16. With our comprehensive size range from 10mm to 120mm inner diameter and various length options, CS offers customizable solutions for your most challenging industrial bearing requirements, all manufactured to precise tolerances in our Taiwan facility with over 33 years of bearing expertise.
