SKF Kullager, 100 mm ID, 180 mm UT, Löpring bredd 34 mm

This versatile ball bearing from SKF can handle both radial and axial loads and handle them at high speeds. It has an inside diameter of 100 mm and an outside diameter of 180 mm, with a race width of 34 mm. As an open-type ball bearing, it's easy to re-lubricate, and the lubricant can travel freely around the bearing. This type of bearing is suitable for clean environments where you don't need to worry about contamination from dirt.

• Minimal friction torque means lower operating temperature and reduced energy use

• Heavy-duty gearboxes

Deep-groove ball bearings have an inner ring and an outer ring with ball bearings sitting in a smooth raceway in between. They're a popular choice as they produce little noise during operation.

Choose oils when it comes to lubricating open bearings. They're less viscous than grease and enable efficient running, with lower torque and higher speeds.
