6203-2RS1/C3GJN Deep Groove Ball Bearing 17x40x12mm Double 2RS1 Rubber Seal C3GJN Special Clearance Bearing

1. Product Overview

6203-2RS1/C3GJN single row deep groove ball bearing, standard metric dimension 17×40×12mm.
Code Definition

• 6203: Light-duty small 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 supports 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 small drive motors, ventilation cooling fans, handheld power tools, textile rollers and light automation transmission assemblies.

2. Technical Specifications

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 debris
3. Matched GJN high-temperature anti-oxidation grease avoids grease loss and dry burning during long operation
4. Mirror polished steel balls deliver low friction, quiet and stable continuous 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. Lightweight stamped steel cage reduces rotation torque for energy-saving stable running
8. Customizable precision grade, special lubricant formula and outer ring laser marking

4. Application Scenarios
