6011-2RS1/C3GJN Deep Groove Ball Bearing 55x90x18mm Double 2RS1 Seal C3 Special

1. Product Overview

6011-2RS1/C3GJN single row deep groove ball bearing, standard metric dimension 55×90×18mm.

Code Definition

• 6011: Medium light deep groove ball base model
• 2RS1: Double-sided contact rubber lip seal for dust, water and impurity isolation
• C3GJN: Custom widened C3 radial clearance with matched special anti-high temp grease formula

Classic deep groove raceway can bear radial load and slight bidirectional axial load simultaneously. Double lip contact rubber seals lock internal lubricant and block external dust, water vapor and metal debris. Pre-filled special GJN high temperature anti-oxidation grease, stable performance under continuous high-speed and temperature rise conditions. Widely matched to medium industrial motors, ventilation fans, light reducers and general automation transmission equipment.

2. Technical Specifications

Drawings and high-temperature long-running noise durability test reports available on request.

3. Core Advantages

1. Custom C3GJN special clearance avoids bearing clamping caused by thermal expansion at high speed
2. Double 2RS1 contact rubber seals fully isolate dust, water mist and abrasive particles
3. Matched GJN high-temperature anti-oxidation grease reduces grease volatilization and dry burning
4. Mirror polished steel balls realize low friction, low noise and stable continuous rotation
5. Universal deep groove structure bears radial load and light bidirectional axial load
6. Unified international standard dimensions for direct one-to-one replacement
7. Reinforced stamped steel cage prevents ball shift under long-time vibration
8. Customizable precision grade, special lubricant formula and outer ring laser marking

4. Application Scenarios

• Medium-sized industrial driving motors, ventilation fans and blowers
• Light-duty gear reducers, packaging and conveying machinery transmission parts
• Agricultural light rotary equipment and textile medium roller assemblies
• Small construction light machinery and general factory automation equipment
• Household large ventilation equipment and medium-speed rotary auxiliary components

Suitable for OEM supporting production and after-sales maintenance of medium light industrial general machinery.
