SKF Needle Roller Bearing, 30mm Inside Diameter, 45mm Outside Diameter - NKI30/20TN
This SKF needle roller bearing is designed for applications requiring high load capacity in a compact form. With a 30mm inner diameter and 20mm width, it features a non-metallic cage and an open-end configuration, making it suitable for various industrial setups. The bearing supports high-speed rotation with reduced friction and is constructed from carbon chromium steel for enhanced strength and durability.
Features & Benefits
• Compact radial design accommodates space-limited installations
• Non-metallic cage improves lubrication flow and reduces noise
• High static load rating of 52 kN and dynamic load rating of 27.5 kN
• Open-end design facilitates easier lubrication and inspection
• Suitable for operation at speeds up to 13,000 rpm under oil lubrication
Applications
• Suitable for gearboxes and automotive transmissions
• Can be used in industrial machinery and power tools
• For pumps, compressors, and agricultural equipment
What is the limiting speed of this bearing?
The bearing supports a limiting speed of 13,000 rpm with oil and 7,500 rpm with grease.
Is this bearing suitable for axial loads?
Needle roller bearings primarily support radial loads; axial load capability may require additional components.
What material is used for the rolling elements?
The rollers are made from carbon chromium steel, offering excellent fatigue resistance.
