7328 BCBM

The 7328 BCBM is a high-performance single row angular contact ball bearing engineered for demanding industrial environments where precision and reliability are non-negotiable. Featuring a substantial 140mm bore, 300mm outside diameter, and a 62mm width, this unit is designed with a 40-degree contact angle to efficiently manage heavy radial loads and significant thrust loads in a single direction. The "BCBM" suffix denotes its robust construction, utilizing a machined brass cage that provides superior guidance for the rolling elements, ensuring stable operation even under high-speed conditions. Unlike standard bearings, its internal geometry is optimized to reduce friction and heat generation, which directly translates to a longer service life for your heavy-duty rotating equipment.

For applications requiring bidirectional axial support, these bearings are frequently installed in pairs or sets (back-to-back or face-to-face). The 7328 BCBM excels in high-speed machinery such as large centrifugal pumps, industrial gearboxes, and electric motors where axial rigidity is critical. With a dynamic load rating of approximately 302 kN and a limiting speed that supports rigorous industrial cycles, this bearing offers a low-maintenance solution for minimizing downtime. Its open design allows for flexible lubrication strategies, making it a versatile choice for engineers looking to optimize the mechanical efficiency of large-scale power transmission systems.
