6209-2RS1/C3GJN Deep Groove Ball Bearing 45x85x19mm Double 2RS1 Rubber Seal C3GJN Special Clearance Bearing

1. Product Overview

6209-2RS1/C3GJN single row deep groove ball bearing, standard metric dimension 45×85×19mm.

Code Definition

• 6209: Medium size deep groove ball base model
• 2RS1: Double-sided contact rubber lip seal, isolates dust, moisture and fine abrasive particles
• C3GJN: Custom widened C3 radial clearance matched with exclusive anti-high-temperature oxidation grease

Classic deep groove raceway bears radial load and slight bidirectional axial load simultaneously. Dual contact rubber seals lock internal lubricant and block external pollutants. Pre-filled special GJN high-temperature grease, effectively avoids grease volatilization and dry friction under continuous high-speed temperature rise. Widely used for medium industrial drive motors, large cooling fans, heavy light conveyor rollers, packaging machinery and general transmission equipment.

2. Technical Specifications

Model: 6209-2RS1/C3GJN

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

3. Core Advantages

1. Custom C3GJN special clearance prevents bearing seizure caused by high-speed thermal expansion
2. Double 2RS1 contact rubber seals fully block dust, water mist and tiny metal abrasive debris
3. Matched GJN high-temperature anti-oxidation grease avoids grease loss and dry burning after long continuous operation
4. Mirror polished steel balls deliver low friction, quiet and stable high-speed rotation
5. Universal deep groove structure bears radial load and light bidirectional axial load
6. Global unified standard dimensions for direct one-to-one aftermarket replacement
7. Reinforced stamped steel cage avoids ball displacement under long-time heavy vibration
8. Customizable precision grade, special lubricant formula and outer ring laser marking

4. Application Scenarios

• Medium industrial drive motors, large ventilation cooling fans and blowers
