SKF 1 Row Deep Groove Ball Bearing, 20 mm ID, 47 mm OD, Glass Fibre Cage, Steel Balls 6204 ETN9

SKF 6204 ETN9 is a precision single row deep groove ball bearing engineered for high temperature performance in demanding industrial environments. This bearing features a 20 mm inner diameter and a 47 mm outer diameter, making it suitable for a wide range of rotary applications where reliability and low maintenance are crucial.

The glass fibre reinforced polyamide cage (TN9 design) ensures reduced friction and improved efficiency, while the steel ball and race construction provides outstanding durability and resistance to wear. With an open end type, this bearing is ideal for installations where cooling and rapid rotation are required, and no additional grease is needed after installation.

The bearing delivers a dynamic load rating of 15.6 kN and a static load rating of 7.65 kN, handling both radial and axial loads effectively. It can operate at speeds up to 20,000 rpm, making it a preferred choice for high-speed conveyors, machine tools, and material handling equipment.

Designed for versatility, the 6204 ETN9 performs well in dry, hot conditions and is suitable for use over a broad temperature range, from -30°C to 150°C. Its internal clearance is CN, providing standard clearance for most general applications.

Applications include agricultural machinery, food processing lines, medical equipment, printing presses, wind turbines, and material handling systems, where energy efficiency and reliability are critical.

The bearing conforms to quality assurance standards and has a light series designation for reduced mass without compromising strength. Easy to install, it supports low maintenance operations and cost-efficient energy consumption.
