7328BM Angular Contact Ball Bearing (140×300×62 mm)

Dimensions (d×D×B): 140×300×62 mm
Contact Angle: Standard 40-degree contact angle (B series) for high axial thrust capacity.
Cage Material: Machined solid brass (M) for exceptional durability under high centrifugal forces.

Product Overview:The 7328BM is a monumental single-row angular contact ball bearing, sized at 140×300×62 mm. It is specifically structured to sustain heavy combined loads—managing both high radial forces and unidirectional axial thrust simultaneously. This bearing is a staple in high-performance industrial centrifuges, blowers, and heavy-duty pumps. The "BM" designation highlights its precision-machined solid brass cage, which offers superior heat dissipation at high rotational speeds. Every unit is strictly inspected in our dedicated clearance-matching facility to ensure optimal contact angle integrity.

OEM & Customization Services:For B2B clients targeting the heavy industrial sector, we offer specialized packaging solutions, including vacuum-sealed VCI (Vapor Corrosion Inhibitor) bags and reinforced, brand-stamped wooden crates to protect the bearing during global transit.
FAQ:

Q: Why use a machined brass cage instead of stamped steel?A: Brass cages provide better self-lubricating properties, withstand higher operating temperatures, and resist vibrations better in massive machinery.
Q: Can the 7328BM be mounted in pairs?A: Yes, they can be universally matched in our facility for back-to-back (DB), face-to-face (DF), or tandem (DT) mounting arrangements.
Q: What is the dynamic load rating for this bearing?A: Due to its large cross-section and 40-degree angle, it possesses an exceptionally high dynamic load rating designed for continuous industrial operation.
