QJ 218 N2MA

Designed for high-performance industrial environments like gearboxes and centrifugal pumps, the QJ 218 N2MA is a 90mm-bore four-point contact ball bearing that manages substantial axial thrust from both directions within a compact footprint. Its split inner ring allows for a maximum ball complement, effectively packing the load-carrying capacity of a double-row arrangement into a single-row width. To ensure the unit remains secure under heavy torque, the "N2" designation indicates two locating slots on the outer ring side face to prevent rotation within the housing. This is paired with an "MA" machined brass cage-centered on the outer ring-to provide superior stability and optimized lubricant flow during high-speed operations. With its 35° contact angle and high-precision geometry, it stands as a space-saving powerhouse for any application where axial rigidity and bidirectional load handling are critical.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
