What is the YRT turntable bearing
Among the various categories of bearings, YRT turntable bearing is a rotary mechanism supported by inner ring and outer ring rotation, which is mainly divided into three series of YRT type, YRTS type and YRTM type. The three series of bearings have the same mounting size, different internal structure and similar performance.
YRT turntable bearings are composed of three rows of rollers, two rows of axial rollers to ensure the stability of the axial bearing capacity, a row of radial rollers to ensure that the bearing can withstand the role of radial force and overturning torque, suitable for the axial bearing rotary mechanism.Mainly used in CNC machine tool manufacturing industry, as its core components, domestic YRT series bearing demand is more dependent on imports, domestic YRT turntable bearing precision parameters standard is subject to the international manufacturers.Here are the three types.1. Type YRTYRT table bearing is composed of a thrust/centripetal seat ring, a thrust/centripetal shaft ring, a thrust washer, two needle roller cage components and a set of centripetal cylindrical rollers.The seat ring and shaft ring are provided with screw holes for equalizing the cloth.This type of bearing has high axial and radial bearing capacity.2.YRTS type (radial nylon retainer)The nylon retainer is adopted for the radial roller, so that YRTS bearing has the characteristics of high limit speed and very low and stable friction torque. Therefore, this kind of bearing is suitable for the engine with torque.3.YRTM type (including steel grating measuring system)YRTM is a two-way thrust cross tapered roller bearing with steel grating ruler, YRT combined bearing, and YRT turntable bearing. The manufacturer said that this bearing can constantly monitor and adjust the rotary accuracy of two-way thrust cylindrical roller combined bearing, so as to ensure the high-precision operation of the machine.
