Product Overview
The FAG QJ219-N2-MPA is a four-point contact bearing derived from angular contact ball-bearing geometry. Its split inner ring allows a large ball complement and enables one bearing position to support axial load in both directions together with a limited radial load.
Two locating slots identified by the N2 suffix help prevent the outer ring from turning where the housing arrangement uses a suitable locating element. The MPA suffix identifies an outer-ring-guided machined brass cage.
Four-point contact bearings are sensitive to surrounding fit, internal clearance and load distribution. The complete suffix and bearing arrangement should be confirmed before replacing another QJ219 variant.

Compatibility and Selection Notice
A four-point contact bearing is not automatically interchangeable with a conventional single-row angular contact bearing. Confirm the housing slot arrangement, radial load share, axial clearance, fits and surrounding bearings.
Verify the complete QJ219-N2-MPA designation, dimensions, speed, lubrication, operating temperature and current manufacturer data for the final duty.

MAVORIX Bearing Sourcing Support
MAVORIX is an independent China-side sourcing and supplier coordination partner, not the bearing manufacturer or an authorized distributor. We can help organize mixed bearing lists, compare complete designations, request supplier documents, coordinate label and dimension checks, and consolidate MRO shipments.
For a replacement inquiry, send the full suffix rather than only the basic bearing number. Related support is available through our industrial sourcing, electrical and mechanical parts, spare-parts sourcing and contact pages.
