Product detailed description
Bearing - NN 3018 KMNA P51 ZKL
NN 3018 KMNA P51 ZKL double-row cylindrical roller bearing
An NN 30-series bearing uses two roller rows to provide very high radial load capacity and rigidity with a relatively small cross-section. The outer ring has no guide flanges, making the bearing separable and allowing axial displacement between shaft and housing in both directions. It therefore acts as a radial non-locating bearing; another component must provide axial location.
Key features
- Dimensions: 90 mm bore, 140 mm outside diameter and 37 mm width.
- Design: precision NN 30-series double-row cylindrical roller bearing.
- Loads: very high radial loads; not intended to carry axial load.
- K bore: 1:12 taper for precise clearance and rigidity adjustment.
- P51 configuration: increased accuracy combined with specified reduced radial clearance in the manufacturer's designation system.
- Brand: ZKL.
Exact KMNA P51 variant
The KMNA P51 characters form an integral part of the manufacturing configuration. The basic NN 3018 designation or similar variants with a different cage, bore, clearance or accuracy are not automatically interchangeable. Keep the matching rings of this precision variant together as one set.
Applications and mounting
Typical applications include machine-tool spindles, precision grinding machines, rolling equipment and other positions requiring high radial rigidity and accurate running. Mounting on the taper requires measurement of radial-clearance reduction or axial drive-up the machine documentation. The open bearing needs suitable lubrication, cleanliness and separate axial location. Verify the complete designation NN 3018 KMNA P51 ZKL before ordering.
