Bearing - NN 3022 KP 52 ZKL

Product detailed description

NN 3022 KP 52 ZKL is a double-row cylindrical roller bearing with dimensions of 110 × 170 × 45 mm. The NN design has two rows of rollers, guiding flanges on the inner ring and a flangeless outer ring, allowing axial displacement between the rings. The legacy KP52 designation denotes a tapered bore, P5 accuracy and reduced C2 radial internal clearance.

Key features

• High radial capacity: two rows of rollers provide high rigidity and accurate running under substantial radial loads.
• Tapered bore: axial drive-up on a tapered journal allows precise adjustment of operating clearance or the required preload.
• P5 accuracy and C2 clearance: intended for precision arrangements; the smaller initial clearance requires especially careful mounting and post-installation verification.
• Axial displacement: the bearing does not carry axial loads but permits compensation for thermal shaft expansion; axial location must be provided by another design element.
• Dimensions: 110 mm bore, 170 mm outside diameter and 45 mm width.

Installation and lubrication

During mounting on the taper, monitor axial drive-up and the resulting radial clearance with suitable measuring equipment; excessive drive-up can quickly create unwanted preload in a C2 bearing. Never transmit mounting force through the rollers. Provide clean lubricant, accurate alignment and a reliable lubricant supply. Before ordering, verify the full designation NN 3022 KP 52 ZKL, accuracy, clearance and the design of the separate axial locating system.
