It combines excellent sliding properties from PTFE and special fillers with the strength and dimensional stability of metal materials!
The "Daidain DDK05" is a completely oil-free bearing that requires no lubrication at all. It has a low friction coefficient and excellent wear resistance under unlubricated conditions, with a wide operating temperature range. A copper-tin alloy is sintered in a porous form on a steel backing, and it is lined with a mixture of polytetrafluoroethylene (PTFE) and special fillers. 【Features】 ■ Low friction coefficient and wear resistance under unlubricated conditions ■ No stick-slip phenomenon due to low friction coefficient ■ High load capacity ■ Wide operating temperature range ■ Excellent chemical resistance *For more details, please refer to the PDF document or feel free to contact us.
