What are the dimensions of this deep groove ball bearing?

This bearing has an inside diameter of 40 mm, an outside diameter of 80 mm, and a width of 18 mm with a cylindrical bore.

What are the benefits of a hybrid ceramic bearing?

The ceramic balls provide electrical insulation, higher wear resistance, reduced friction, and allow for higher rotational speeds.

What protection does the 2RZ sealing provide?

The 2RZ seal features low-friction seals on both sides, keeping the lubricant inside while preventing dirt and dust from entering.

What does the C3 radial internal clearance mean?

The C3 designation indicates greater radial internal clearance than normal, suitable for high rotational speeds and thermal expansion.

What material is the TN9 cage made of?

The TN9 cage is made of glass-fibre reinforced polyamide (plastic), ensuring low weight and smooth, quiet operation.

Product description

Hybrid ceramic single row deep groove ball bearings with seals on both sides have rings made of bearing steel and rolling elements made of bearing grade silicon nitride, which make the bearings electrically insulating. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out. The ceramic rolling elements not only provide protection from electric current damage but also, when compared to same-sized bearings with steel rolling elements, provide enhanced bearing performance, extended bearing service life, higher speed capability, high wear-resistance, high bearing stiffness, reduced risk of smearing and false brinelling, and less sensitivity to temperature gradients, making them suitable for use in dificult conditions and contaminated environments.
