SKF NJ 304 ECP Series Roller Bearing, 20mm Inside Diameter, 52mm Outside Diameter - NJ 304 ECP

This roller bearing is a single-row cylindrical roller unit designed to support radial loads in rotating assemblies where compact, high-speed operation is required. It combines steel rolling elements and races with a non-metallic cage to maintain roller separation and stable operation, offering a balance of load capacity and rotational performance for industrial applications.

Features and Benefits:

• 35.5 kN dynamic load capacity for sustained operational loads
• 26 kN static load capacity for short-term Peak loads
• 18,000 r/min limiting speed for high-speed rotation
• CN internal clearance to accommodate thermal expansion
• Non-metallic cage reduces friction and limits wear
• Steel rollers and races provide Durable rolling contact

Applications

• Suitable for high-speed spindle support in machining
• Ideal for conveyor idler shafts with heavy radial load
• Used with electric motor bearings requiring Compact form
• Can be used for gearbox intermediate shaft support
• Suitable for rotating equipment in automated assembly lines

What bore configuration does this bearing use?

It uses a cylindrical bore designed for slip-fit or adaptor mounting.

How many rows of rollers are present inside the bearing?

There is a single row of cylindrical rollers.

What materials contact directly during operation?

Rolling elements and races are steel while the separator is non-metallic.

What race width affects axial space in an assembly?

The race width measures 15 mm, influencing the axial envelope.

What are the internal dimensional values relevant to shaft and housing?

The inside diameter is 20 mm and the outside diameter is 52 mm.
