What are the dimensions of this SKF ball bearing?

This ball bearing has an inside diameter of 25 mm, an outside diameter of 47 mm, and a width of 12 mm.

What is the benefit of hybrid ceramic balls?

Silicon nitride balls provide electrical insulation, higher wear resistance, and support higher speeds than standard steel balls.

What does the C3 clearance designation mean?

C3 denotes a radial internal clearance greater than normal, accommodating thermal expansion and high rotational speeds.

What sealing type is fitted to this bearing?

It features 2RSL low-friction contact seals on both sides to exclude contaminants while minimizing frictional drag.

What material is the bearing cage made from?

This bearing uses a TN9 snap-type cage made of glass-fibre reinforced polyamide.

Product description

Hybrid ceramic single row deep groove ball bearings with low-friction 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 low-friction seals provide better sealing effectiveness than shields and non-contact seals, thus providing significantly prolonged bearing service life, yet they can still operate at the same speeds as shields. 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.
