Details

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. 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. 2RSL : Sheet Steel Reinforced Low Friction Seal Of Acrylonitrile-Butadiene Rubber (NBR) On Both Sides Of The Bearing, TN9 : Injection Moulded Snap-Type Cage Of Glass Fibre Reinforced Polyamide 6,6, Ball Centered, 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.
