8 micron, NRRO is 0.
07 micron, the RRO of machine tool main shaft was achieved 1.
1 micron, NRRO was achieved 0.
15 micron. Bearing was used need not clean bearing and need not add those who pour lubricating oil to pack way, the material that pack was used can have resource reborn stuff. Additional, regard environmental protection as countermeasure, reduced attrition loss 30% ~ 50% . Still do not use the material of harmful environment additionally. This bearing uses ball of faster than metallic ball tigidity pottery and porcelain. The precision that raising a ball while, the precision that still raised inner ring and outer lane groove and maintain implement dimension precision, NRRO (Non Repeatable Run-Out, asynchronous brace up place precision) reduced the 1/2 previously. The high accuracy that passes bearing is changed, can raise the precision of main shaft roll of the machine tool, return the quality that can improve accurate component surface and mould cutting range. New product plans to appeared on the market in April 2007. CNC Milling CNC Machining
