Looking for a way to prevent electrical erosion in your ball bearing systems? Turn to this INSOCOAT ball bearing from SKF. It's coated with an insulating aluminium-oxide layer that's applied through a sophisticated plasma-spray process for a high-quality finish. This keeps electrical shock and high-frequency currents from passing through the bearings, reducing the risk of damage to contact surfaces. The bearing is made from steel for durability and corrosion resistance, making it a good choice for electric motors and generators in harsh industrial settings.

• Open end type
• Aluminium-oxide layer for protection against corrosion
• Inside diameter of 80 mm
• Outside diameter of 170 mm
• Race width of 39 mm
• Limiting speed of 7500 r/min

• Railways and other locomotive power sectors
• Energy and utility industries
• Printing industry

When bearings are exposed to humidity, moisture can penetrate the insulating material. This reduces the effectiveness of electrical insulation and shortens the service life of the bearing. To protect against this effect, INSOCOAT bearings are treated with a unique sealant.
