FAG QJ 1244 N2 MPA C3 - 220 x 400 x 78 mm

FAG QJ 1244 N2 MPA C3 - Four‑Point Angular Contact Ball Bearing 220 x 400 x 78 mm

The FAG QJ 1244 N2 MPA C3 is a top-tier four‑point angular contact ball bearing engineered for demanding industrial applications. With a 220 mm bore, 400 mm outer diameter, and 78 mm width, it’s built to handle both radial and axial loads efficiently.

• N2 - two retaining grooves in the outer ring for secure axial positioning.

• MPA - machined solid brass cage guided by outer ring for rigidity and heat resistance.

• C3 - increased internal clearance for high-temperature and high-speed operations.

• Split inner ring - simplifies mounting on shafts without removal.

• Load capacities: dynamic Cr ≈ 570 000 N, static C₀r ≈ 980 000 N; limiting speed ~2850 rpm; temperature rating up to 200 °C.

Key Features

• Dimensions: 220x400x78 mm

• Four‑point contact design: supports bidirectional axial & radial loads

• Brass cage and grooves: optimal stability at high speeds

• Split ring and C3 clearance: easy installation & thermal compensation

• Designed for heavy industries: turbines, gearboxes, mills, conveyors
