Description
Overview — Deep Groove Bearing C3
The Deep Groove Bearing C3 (Part Number AM1030) is a precision-engineered, single-row ball bearing designed for gearbox main housings. With its extra internal clearance, the bearing delivers smoother performance under high speed and temperature. Because the clearance allows for more radial play, it prevents binding and extends service life in marine gearboxes.

Marine Applications — Bearings with C3 Clearance
Marine gearboxes are exposed to saltwater, heat, and fluctuating loads. Consequently, this bearing provides consistent shaft rotation, reduces scuffing, and enhances gearbox longevity. It is well suited for recreational boats, racing craft, and commercial vessels that demand reliable performance.
Extended Reliability
Compared to standard clearance bearings, the C3 version improves lubrication flow and tolerates thermal expansion more effectively. As a result, operators experience longer service intervals and reduced downtime, making it a dependable choice for demanding marine environments.
