SKF 6308-2RZTN9/HC5C3WT Deep Groove Ball Bearing 40 × 90 × 23 mm

Overview

Hybrid ceramic deep groove ball bearing with seals on both sides

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.

Selection guidance

Select by bore, outside diameter, width, sealing type, internal clearance, speed rating, and actual radial/axial load conditions.
