3 tips: How to judge there are safety hazards in bearing operation by watching and listening?

Bearing is an indispensable part in the mechanical industry, and the quality of bearing affects the operation performance of machinery.We usually is removed bearing for testing, Today FRB BEARINGS teach you new skills: How to judge there are safety hazards in bearing operation by watching and listening?

Observation: should open the bearing box on a regular basis, in order to visual check bearing and oil seal, check of the condition of the near the bearing oil seal to ensure that they are enough to prevent hot liquids or corrosive liquid, gas along the axis of seeping into the bearings.

FRB BEARINGS specializing in crossed tapered roller bearing

Cross roller bearings mainly has two kinds, one kind is crossed cylindrical roller bearing, and another kind is crossed tapered roller bearings, both are rolling on the v-shaped grooves perpendicular, the only difference is crossed tapered roller ring V groove according to the tapered roller Angle is different and different, so that the bearing capacity of larger, higher speed.

The design of cross taper roller bearings (XR/JXR series) can provide high rotation accuracy and rigidity in a small space, which can greatly save material cost.This type of bearing is the two sets of bearing raceway and roller according to the rectangular cross installed together, adjacent roller in the opposite direction, install a isolation block between roller and roller, the roller is also equipped with support gasket, this makes the roller of two and a half into the same space.The angular and conical geometry of the bearing makes the effective span of the bearing several times larger than the actual width of the bearing itself.

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.
