Split roller bearings are designed for easy installation and maintenance, especially in applications where equipment disassembly is difficult. The bearing is split radially into two halves, allowing installation and replacement without removing surrounding components, significantly reducing downtime. They are well suited for heavy-duty and continuous operation environments.
These bearings consist of split inner rings, outer rings, rollers, and cage assemblies, secured by bolted connections. Standard bore sizes range from tens of millimeters to several hundred millimeters, with custom designs available to meet specific equipment structures and operating conditions.
Split roller bearings are widely used in industries such as metallurgy, mining, conveying systems, paper production, large fans, and agricultural machinery. They are particularly suitable for equipment with limited maintenance space or frequent servicing requirements. HSN bearings offer strong structural reliability, high load capacity, and long service life. Through optimized design and strict manufacturing processes, HSN provides efficient and stable solutions for demanding applications.
