SKF NKI Series Roller Bearing, 30mm Race Width, 30mm Inside Diameter - NKI 30/30 TN


This roller bearing is a needle roller type designed to support radial loads in Compact assemblies where a slim cross-section and high load capacity are required. It combines steel rolling elements with a non-metallic cage and is intended for applications demanding precise internal clearance and smooth operation at elevated rotational speeds.

Features and Benefits:


• Steel rollers deliver high dynamic load capacity of 46.5kN
• Non-metallic cage reduces friction and noise during operation
• Internal clearance classified as CN for predictable axial play
• Single-row construction enables slim-profile installations
• Limiting speed rated to 13,000 r/min for high-speed duty
• Static load capability of 85kN resists heavy stationary loads

Applications


• Suitable for Compact transmission shafts in industrial machinery
• Ideal for high-speed rotary actuators and spindles
• Used with gearboxes requiring a round bore fit of 30 mm
• Can be used for automation equipment with tight axial space
• Appropriate for drive systems needing steel roller durability

What bore configuration does this bearing require for mounting?


It is designed for installation on a round bore with a 30 mm inside diameter.

Which material provides the rolling elements and how does it affect wear?


The rollers are steel, which offers enhanced wear resistance under cyclic loading.

How does the cage material influence maintenance intervals?


The non-metallic cage lowers lubrication drag and can extend re-lubrication intervals under similar conditions.

What clearance classification should be expected for axial positioning?


The internal clearance is specified as CN, providing a standardised medium internal play for assembly tolerances.

What operating condition defines its static load handling capability?


The bearing can withstand up to 85kN when subjected to stationary or very slowly applied loads.
