NACHl's self-aligning roller bearings are a common and important industrial part, widely used in a variety of mechanical equipment and construction machinery. It is mainly composed of an outer ring, an inner ring, a roller, a cage and other components, and supports the rotating and swinging shaft through rolling friction. Aligning roller bearing has large radial load capacity and high axial load capacity, as well as excellent self-aligning performance, and can adapt to the relative tilt and axial change between shaft and seat when working.

1.Cylindrical hole· With two rows of steel balls and a curved raceway in the outer ring, self-aligning ball bearings can be actively aligning· and can accept the point of view error between the shaft and the bearing seat. It is suitable for the working condition that simply shows the shaft deflection and the shaft error caused by different centers· Friction is the lowest of all rolling bearings· has only a small temperature rise even at high rotational speeds.2.

Linear motion bearing is a linear motion system produced at a low cost for use with unlimited travel and cylindrical shafts. Because the bearing ball is in point contact with the shaft, the load is small. The steel ball rotates with very little friction resistance, thus achieving smooth motion with high precision. Linear motion bearing metric and Imperial series: Standard type (LM/LME/LMB... UU), adjustable (LM/LME... UUAJ), Open (LM/LME... UUOP); Extended (LM/LME... LUU); Flange type (LMF/LMK/LMH... UU, LMEF/LMEK... UU), flange extension (LMF/LMK/LMH... LUU, LMEF/LMEK...

Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or dynamic loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.Self-aligning roller bearings are divided into two different structures according to the roller cross section shape: symmetrical spherical roller bearings and asymmetric spherical roller bearings.
