UD203 Outer spherical bearing

The outer spherical ball imported bearing is actually a variant of the deep groove ball imported bearing. Although its basic performance should be similar to that of deep groove ball bearings, because these bearings are mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and deflected. In the case of large and other, and the bearing itself is not high enough precision, and some structures are also rough, so the actual performance of the common performance should be marked with a considerable discount compared with the deep groove ball bearings of the same specification. For example, the outer spherical ball bearing with top wire is applied to the through shaft with large stiffness difference and large deflection. This kind of bearing has sealing rings on both sides, which can strictly prevent the intrusion of dirt. It is filled with an appropriate amount of lubricant before leaving the factory. No need to add lubricant, when the jack screw on the protruding end of the bearing inner ring is fastened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load. The outer spherical ball bearing with eccentric sleeve has basically the same performance as the outer spherical bearing with top wire, but the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered hole outer spherical ball bearing is a tapered hole with a taper of 1:12, which can be directly installed on the tapered shaft, or installed on the shoulderless optical shaft with the help of a fixed bushing, and can fine-tune the bearing clearance.

linear ball bearing

A linear ball bearing, also known as a linear motion bearing or linear bushing, is a type of rolling element bearing designed to provide smooth and precise linear motion in a linear guide system. It consists of an outer cylindrical shell, typically made of steel or aluminum, and

Cylindrical Roller Bearings

Cylindrical roller bearings (CRBs) have a simple structure with their cylindrical rollers in linear contact with the raceways. They offer high load capacity under primarily radial loads. Low friction between the rollers and ring ribs makes these bearings suited for high speed rot

Deep groove ball bearings

Deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings have circular arcs of slightly larger radius than that of
