• SKF Heat-Resistant Deep Groove Ball Bearings • SKF ball bearings are designed to increase reliability, reduce complexity, and reduce environmental impact even at high operating temperatures.　Features: Excellent performance in high temperature environments, dry environments, and low rotational speedUse temperature range: -30 → 150 °CSuitable for high speed and very high speedSteel/ceramic ball materialPlain lace typeLow frictionVarious designs, types, and sizes available Why choose deep-groove ball bearingsVersatility - Supports radial and axial loads and is widely cost-efficient in many industries - Low friction torque keeps temperatures low and reduces energy costs when operating equipment such as conveyor beltsLow maintenance - No additional lubrication required after installation Use: Agricultural food processing Machinery toolsRaw materials processingMedical/pharmaceutical printing Wind power generation Inner ring diameter range: 6 mm → 40 mm Internal/external design: 2RS1 - Contact seal NBR on both sides, 2RSH - Contact seal NBR Z on both sides, 2Z - Shield on one or both sides 2RSL - RSL Low Friction Contact Seal on both sides of bearing 2RZ - RZ Low Friction Non-Contact Seal on both sides of bearing 2ZNR - Shield on both sides, Snap Ring Groove in outer ring, NR - Snap Ring Groove in outer ring, E-Reinforced Ball Set Cage Design TN9 - Glass Fiber Reinforced Polyamide 66 Cage, Centrally rolled stainless steel lubricated GJN-NLGI scale with a concentration of 2 polyurea thickener for a temperature range of -30 → +150 °C (standard fill grade) VT162 - Klueber Isoflex Topas NB52 lubricated with grease WT-NLGI scale with a concentration of 2 → 3 polyurea thickener for a temperature range of -40 → +160 °C Grease with a concentration of 2 → 3 lithium thickener for LHT-NLGI scale with a temperature range of -30 → +150 °C Grease with a concentration of 2 → 3 polyurea thickener for HT-NLGI scale with a temperature range of 40 → + 66 °C (standard fill grade) Precision/Clearance C2 - small internal radial clearance, C3 - Internal clearance greater than normal C4 - Radial internal clearance greater than C3 - Radial internal clearance greater than C5 - C4
