SW B-1612 High Precision Cylindrical Roller Bearing (80x140x26mm) - Heavy Load Industrial Grade
The SW B-1612 is a robust, high-capacity single-row cylindrical roller bearing designed for demanding industrial environments where high radial loads and moderate speeds are prevalent. Constructed from ultra-clean, high-carbon chromium steel (SAE 52100 equivalent), this bearing features a refined P5 (ABEC-5) tolerance class, ensuring exceptional running accuracy and minimal vibration under load. The optimized roller profile and machined brass cage assembly reduce internal friction and heat generation, significantly extending the service life in applications such as large industrial gearboxes, paper mill calendars, and heavy-duty pumps. Its robust design allows for partial compensation of axial misalignment and superior resistance to shock loading, making it the preferred choice for reliable, continuous operation.
Investing in the SW B-1612 directly translates to reduced maintenance expenditures and maximized operational uptime. SW’s proprietary surface finish treatments and advanced heat stabilization process provide outstanding wear resistance, even in poorly lubricated or contaminated conditions. This bearing is engineered for exceptional longevity, offering dynamic load ratings far exceeding standard requirements for its size class. By minimizing energy consumption through superior internal geometry and providing predictable performance over extended operating cycles, the B-1612 delivers a rapid return on investment, ensuring consistent production schedules across critical infrastructure and manufacturing operations.
