How to select high precision cross roller bearing and YRT turntable bearing?

YRT turntable bearing is a rotary mechanism of outer ring and inner ring support. It is mainly divided into three series: YRT, YRTS and YRTM.How to select high precision cross roller bearing and YRT turntable bearing?

The space of the cross roller bearing can be constrained.In most cases, the axis (or cross roller bearing inner ring) is based on mechanical or other delineation constraints.Therefore, the selection of cross roller bearing type and scale is based on the internal diameter of cross roller bearing.Therefore, the first scale of the standard cross roller bearing is based on the international standard.
Specification method of heavy and complicated of the scale of the cross roller bearing, the best choose on machinery and equipment, standard cross roller bearings,cross roller bearing load on the cross on the roller bearing load, the nature, intrusive, direction is changeable.In general, the extra basic load is shown on the scale.However, axial load and radial load are also important factors for selecting suitable cross roller bearings.When the ball and needle bearing are at the same time, the cross roller bearings generally have higher load capacity and accept larger oscillations and impact loads.


Second, speed.The acceptance speed is based on the type, scale, precision, maintenance type, load, smooth method, and cooling method of cross roller bearings.The cross roller bearing table lists the allowable speed of the cross roller bearing on the smooth and smooth oil.Generally, deep groove ball bearings, active aligning ball bearings and cylindrical roller bearings are suitable for high-speed work.

The accuracy and rotation precision of cross roller bearings are based on ISO and JIS specifications.About the demand of high precision and high speed work machinery, advocate using grade 5 or above precision cross roller bearing, deep groove ball bearings, angular contact ball bearings and cylindrical roller bearing is suitable for high work precision machinery.Rigidity, when cross roller bearings and raceway contact surface compression, will occur elastic deformation.Some mechanical requirements minimize elastic deformation.The elastic shape of roller bearing is smaller than that of ball cross roller bearing.
Otherwise, in some cases the cross roller bearings are preloaded to add rigidity.This program is commonly used in deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer circle of bias, winding shaft and shaft or change, cross roller bearing box and service cooperation fault offset inside and outside the circle.In order to avoid too big, active aligning ball bearing, active aligning roller bearing, or aligning bearing seat is a better choice.Voice frequency and torque, rolling bearings are produced according to high precision specifications, so the voice and torque are small.Deep groove ball bearings and cylindrical roller bearings are suitable for occasions with low noise and low torque.

Equipment and disassembly, some use of the occasion demand is often disassembled and equipment, in order to ensure the timing of the detection and repair.The inner and outer rings can be separated from the equipment's cross roller bearings such as cylindrical bearings, needle bearings, and conical bearings are very suitable for this occasion.With the help of the shaft sleeve, the proactively aligning ball bearing and the active aligning roller bearing of the conical groove simplify the equipment procedure.
