MKX, NKXR series, diameter D, and D2 Bearings with inner rings have CN radial internal clearance.Grease lubrication and relubrication interval time of needle roller bearings:

The thrust component B of the bearing with the suffix Z has been filled with the lithium complex soap grease specified in DIN51825-KP2N-25.. The diameter of the inscribed circle is a limit inscribed circle formed by a group of needle rollers arranged on the outer raceway without clearance. Before installation, the inscribed circle diameter Fw is within the tolerance zone F6.

Before the bearing is put into operation, the centripetal parts should be lubricated with grease of similar quality and compatible with the thrust parts. The size of the inscribed circle diameter Fw is the determining factor for the radial internal clearance of a bearing without an inner ring.

The relubrication interval non-standard bearing of thrust and centripetal components should be calculated separately, and the shorter value shall be used as the relubrication interval. and inner ring width (-0. Accuracy: Geometric and dimensional tolerances are determined in accordance with the tolerance level PN specified in DIN 620.
