The self-aligning roller bearing is a bearing with drum-shaped rollers assembled between the inner ring having two ball races and the outer ring having a spherical ball race. The curvature center of the ball race surface of the outer ring agrees with the bearing center, and the ball race surface of the outer ring tilts at a certain angle relative to the axle of the bearing. In this way, it has the same self-aligning function just like the self-aligning ball bearing. In case of the deflection of the axle and housing, the self-aligning roller bearing can carry out self adjustment without adding load. It can bear a radial load and axial loads in two directions. The self-aligning roller bearing, which has a high radial load carrying capacity, is suitable for a heavy load and an i***ct load. Since the inside diameter of the inner ring is a tapered bore, the bearing can be directly installed, or be installed onto a cylindrical axle through an adaptive sleeve and a ***achable barrel. The cage of the bearing can be a steel plate stamping cage, a polyamide forming cage or a copper alloy machined cage.
The bearing, which has attractive design features, can not be replaced in many applications with higher requirements.
The self-aligning roller bearing is robust with its inherent self-aligning function. The two rows of rollers enable the bearing to bear a heavy load. The self-aligning roller bearing not only has a wide range of size, but also includes special designs such as bearings for vibrating screens and similar applications.
The self-aligning roller bearing can bear both a greater radial load and a certain axial load. As the outer ring ball race of the bearing is spherical, the bearing has a self-aligning function and still works when the relative titling degree between the inner ring center line and the outer ring center line is from 1 to 2.5 degrees.
The self-aligning bearing has two types of bores, namely a cylindrical bore and a conical bore. The conicity of the conical bore is 1:12 or 1:30. In order t |
