DAIDYNE DDL05
This environmentally friendly, lead- free, self-lubricating metal-polymer bearing requires no additional lubricant. It combines a low-friction polytetrafluoroethylene (PTFE) bearing surface with the strength and dimensional stability of a metal backing. Bearings less than 10mm in diameter can be produced with 0.5mm wall thickness. This can produce more compact, lighter weight designs for solenoids and other applications
Product Details
Features
