These bearings are designed to accommodate shaft deflection when running and will also cope with initial misalignment. The double row bearing is designed primarily to withstand radial load with a small capacity for axial load. Also available with ring seals (rubbing seals) made from oil-resistant, non-wearing synthetic rubber with steel reinforcement on both sides (Type 2RS1).

ETN9 and KTN9 are Open self-aligning bearings without a seal available in parallel or Taper bores.

2RS1TN9 are sealed (NBR) bearings packed with grease with a lithium thickener suitable for temperatures from -40°C to + 100°C. They are sealed for life, so should not be heated above 80°C before mounting and must not be washed out under any circumstances.

TN suffix denotes polyamide cage

This innovative self-aligning ball bearing from SKF is designed to avoid shaft deflection and misalignment. With low friction generation, it's particularly suited to high-speed applications with low axial loads. The sealed bearing comes pre-greased for maintenance-free lifetime usage. High-grade balls and advanced raceways ensure smooth, low-noise operation even at high speeds. This product is strictly tested for adherence to quality and compliance with British and EU electrostatic discharge standards.

• Fibreglass-reinforced PA (nylon) cage for strength
• 30 mm inside diameter, 62 mm outside diameter
• Operating temperature range of -40°C to +100°C
• Static load rating of 4.65 kN
• Dynamic load rating of 15.6 kN
• Adheres to ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 electrostatic control standards

• Pumps, industrial fans and centrifugal separators
• Agricultural and food processing equipment such as cereal mills and fruit shredders
• Fabric industry equipment such as ring spinning or twisting machines

Since sealed self-aligning ball bearings offer maintenance-free lifetime usage, they're the preferred choice for high-speed original equipment manufacturing. They significantly reduce noise and vibrations and can be useful for industrial fans and blowers.

SKF uses high-quality sheet steel reinforced with NBR (nitrile butadiene rubber), which is oil and water-resistant.
