QJ 214 N2MA

Space constraints in heavy machinery design often force engineers into a corner, but that's exactly where the QJ 214 N2MA really shines. Rather than defaulting to a bulky double-row setup, you can use this specific four-point contact ball bearing to manage heavy bidirectional axial loads-along with fractional radial forces-while taking up a fraction of the usual axial width. The internal geometry is what actually makes the difference here. With a 35-degree contact angle and a solid machined brass cage, the QJ 214 N2MA reliably pushes rotational speeds up to 9,000 rpm under pretty tough conditions. Mounting it in the field is surprisingly straightforward since the split inner ring lets you handle the outer assembly independently. Combine that with integrated locating slots that physically stop the outer ring from creeping or rotating in its housing, and it's easy to see why the QJ 214 N2MA is trusted for complex, high-precision alignments.

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