Description

Ball screw support bearings performance1.ZYS precision Ball screw support bearing is a kind of one-direction angular contact thrust ball bearing (60° contact angle) with high accuracy,Website:http://www.zys-bearings.com, high speed, high axial rigidity, low friction, long life and transient high/low speed conversion. The bearing is particularly suitable for the ball screw support and similar transmitting components in high-speed precision CNC machine tools.?Ball screw support bearingsZYS precision ball screw support bearings including four series: 7602, 7603, BS, BSS. The standard7602 and 7603 series correspond to Chinese Mechanical standard, with the bore diameters from 12mm to 130mm; BS series are non-standard metric and BSS series are inch series.?Ball screw support bearings can support larger axial load in one direction and a certain radial load. These bearings are usually arranged in duplex or multiple sets with the same arranging modes as the way of angular contact ball bearings.2.Sealed ball screw support bearings?In order to meet the developing trend of smaller machine tool with more compact structure, ZYS developed sealed ball screw support bearings. The seals at both ends of bearing can prevent cutting fluid and metal scrap into the bearing.Sealed ball screw support bearings3.Ball screw support bearings unitsZYS ball screw support bearings units refer to combining matched bearings and relevant?accessories together into ball screw support components, with simple mounting, convenient use, reliable operation and such features.According to the different bearings arranging modes, ZYS ball screw support bearing units have three types: BSDU……DF, BSTU……TFT and BSQU……QFC.4.The preload and axial rigidity of high precision ball screw support bearingsThe preload and axial rigidity of high precision ball screw support bearings (Standard Metric)Bearing designationZYSPreloadFa0Axial ? rigidityRaBearing designationZYSPreloadFa0Axial ? rigidityRaKNN/μmKNN/μm760201TN11.4470
