95% Pure Alumina Ceramic Parts Slotted Eyelet Guide For Textile Machinery
Textile Ceramic eyelet guides (Alumina ceramic eyelet ) apply to the coiling machine and spinning and weaving machinery, is in common use fault silk another piece , is used to demand no high fault silk occasion. Silk thread slides when the job, in china eye outside, for reducing friction, must raise material hardness , smoothness and form. Our company selects and uses 99%'s Al2O3 , hardness greater than HRa88 , density 3.85, surpasses essence throwing Ra0.2.
The cramic eyelet is used to set less (friction is also less) location of pressure right. For cost reduction , according to using a request, smoothness polishing handicraft is allotted being (0.8 throw Ra) roughly , is throw (Ra accurate 0.4), surpasses essence throwing (Ra0.2). Be that single face is super-accurate at the same time mark throw and two-sided super-accurate throw. Specification of china eye many, select and use specification listing in common use in sopport a customer the day afer tomorrow now, also may demand making to order according to the customer.
