Details

Hybrid ceramic single row deep groove ball bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride, which make the bearings electrically insulating. Deep groove ball bearings are the most widely used bearing type, especially in electric motors. 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. These characteristics make them suitable for use in difficult conditions and contaminated environments. Features are : Protected against electric current damage, Especially suited for use in difficult conditions and contaminated environments, Typical benefits of single row deep groove ball bearings. 2Z : Shield Of Pressed Sheet Steel On Both Sides Of The Bearing, TN9 : Injection Moulded Cage Of Glass Fibre Reinforced Polyamide 6,6. Rolling Element Centred, HC5 : Rolling Elements Of Silicon Nitride, C3 : Internal Clearance Larger Than Normal, WT : Grease Fill For Low As Well As High Temperature e.g. Range -40 ~ 160°C. WT Or A Two-Figure Number Following WT Identifies The Actual Grease. An Additional Letter Or Letter/ Figure Combination As Mentioned Under “HT” Identifies Filling Degrees Other Than Standard.
