SKF 1204 ETN9 Self Aligning Ball Bearing- Open Type 20mm I.D, 47mm O.D

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
