GQZ 6011-2RS1/C3 Deep Groove Ball Bearing 55×90×18mm Double Contact Rubber Seals C3 Radial Clearance

6011-2RS1/C3 is single row deep groove ball bearing.

• 2RS1: Double-sided reinforced NBR contact rubber seals, effectively block dust, moisture and fine contaminants, prevent grease leakage.
• C3: Increased radial internal clearance, compensates thermal expansion during continuous high-speed operation.

  It withstands radial load and light bidirectional axial load. Deep raceway design delivers low friction, low vibration and stable rotation. Pre-filled grease realizes long maintenance-free operation.

  Alternative versions: open type 6011, metal shield type 6011-2Z/C3, standard CN clearance 6011-2RS1. Widely used for industrial electric motors, cooling fans, water pumps, small compressors, agricultural machinery and general automation rotary assemblies.

  Formal quotation will be sent within 24 hours upon your inquiry.
