6230 M Deep Groove Ball Bearing 150x270x45 mm | ISO 62 Series – Heavy | Open Type with Machined Brass Cage
This precision bearing utilizes a robust deep groove raceway geometry, enabling stable high-speed performance up to 4,350 r/min (Grease). The 6230 M is engineered to accommodate substantial radial loads as well as axial loads in both directions. The machined brass cage (M) provides exceptional strength and wear resistance, making it exceptionally suited for high-stress applications in heavy industry, power generation, and large-scale pumping systems.

Ideal for a diverse range of heavy-duty and continuous-operation mechanical systems:
Conforming to the popular 62-series, the 150×270×45 mm configuration delivers a high dynamic load rating of up to 187 kN. This robust construction, combined with the strength of the brass cage, ensures reliable performance in applications where substantial radial and axial forces are present.
The one-piece machined brass cage (suffix M) provides superior guidance to the rolling elements, reducing friction and enabling higher speed capabilities compared to standard pressed steel cages. It also offers enhanced durability in applications involving shock loads or vibration.
Engineered for demanding environments, the 6230 M features a precision-machined raceway that ensures consistent, quiet operation. With limiting speeds up to 4,500 r/min, it supports stable, long-life performance in critical equipment like large electric motors and turbine drivetrains.
