BN25-10 are with high temperature, high speed, long life, requires more than 13000r / min high-speed, non-stop continuous work 9,000 hours (about 375 days). Which is the minimum life requirements to meet the continuous work of more than a year.The original high-speed chemical fiber winding head chuck shaft bearing shaft bearing assembly life and speed can not meet the development needs of chemical fiber equipment, through the original deep groove sealed ball bearings to open angular contact ball bearings, the use of Grease lubrication and increase the oil seal, increase the oil chamber and other optimization design, to achieve high speed chuck shaft bearing assembly, high precision, long life performance requirements.
