The 230SM180MA Split spherical roller bearings consist of a split outer ring (divided into two halves), a split inner ring (divided into two halves), drum-shaped rollers, and a split cage. Each component is connected and secured by bolts or locating pins, allowing for independent installation and disassembly without relying on other parts of the shaft or bearing housing.
Split spherical roller bearings offer extremely convenient installation and maintenance, eliminating the need to disassemble adjacent components such as couplings and gears on the shaft, significantly reducing downtime. They possess the self-aligning function of standard self-aligning roller bearings, compensating for misalignment and shaft bending. They have high load-bearing capacity, are impact-resistant, and suitable for hard-to-access equipment locations.
