Non-lubricated service and high-compressive strength improve performance

When a leading manufacturer of light and heavy-duty paper baling equipment needed to replace their failing bronze bushings, we knew CJ self-lubricating bearings had the strength and durability to surpass and outperform.  Boasting a high load of 40,000 psi, plus exceptional wear and load tolerance, non-lubricated CJ bearings gave our client improved equipment uptime and performance rates.

Bronze bearings succumb to sludge

The US is seeing huge gains in community recycling programs, with nearly 45 million tons of paper and paperboard recovered for recycling in 2011 alone.  While this growth means big business for our manufacturing partner, it also places heavy demands on their paper balers and other recycling equipment.

Our client explained that as their baling volumes grew, so did the failure rate of their bronze bushings.  Their challenge was that the grease generated from the oil-impregnated bronze would combine with the paper dust and other production debris to form a thick sludge.  This sludge would then clog and corrode the bearing; necessitating a complete shutdown of the production line while the bearings were changed.  And with each shutdown, production and profits were negatively impacted.

CJ bearings give non-lubricated service, even in dirty environments

After a thorough consultation, our bearing experts recommended replacing the greased-bronze bushings with self-lubricating CJ.  They explained that the dry-running nature of CJ bearings would prevent dirt particles from sticking to the bearing surface and forming the sludge.  CJ bearings have inherent deflection qualities to excel in even the dirtiest of application environments.  And with exceptional vibration and shock resistance already built-in, CJ bearings are able to remain stable in this high-impact baling environment.

Our client was so pleased with the production gains of self-lubricating composite over lubricated bronze, they are now expanding the use of CJ and our Ultracomp bearings to other components of their recycling equipment.
