6313-2RS1/C3GJN Deep Groove Ball Bearing 65x140x33mm Double 2RS1 Rubber Seal C3GJN Special Clearance Bearing

1. Product Overview

6313-2RS1/C3GJN single row deep groove ball bearing, standard metric dimension 65×140×33mm.

Code Definition

• 6313: Large heavy-duty deep groove ball base model, equipped with extra thickened steel balls for outstanding radial load capacity
• 2RS1: Double-sided contact rubber lip seal, fully isolate dust, moisture, metal scraps and fine abrasive particles
• C3GJN: Custom widened C3 radial clearance matched with exclusive high-temperature anti-oxidation special grease

Classic deep groove raceway can bear radial load and slight bidirectional axial load simultaneously. Dual contact rubber seals lock internal lubricant and block external pollutants effectively. Pre-filled dedicated GJN high-temperature grease, which prevents grease volatilization, thinning and dry friction under long-time continuous high-speed temperature rise. Widely applied to large heavy-duty industrial drive motors, large industrial cooling blowers, heavy conveyor rollers, heavy packaging machinery, mining auxiliary equipment and large general heavy-load 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 avoids bearing locking and seizure caused by thermal expansion under long heavy-load high-speed operation
2. Double 2RS1 contact rubber seals fully block dust, water mist, mud and tiny metal abrasive debris for long service life
3. Matched GJN high-temperature anti-oxidation grease reduces grease loss and eliminates dry burning under sustained heating
4. Extra thickened super-finished steel balls deliver ultra-high heavy load capacity, low friction, stable and quiet rotation
5. Universal deep groove design bears radial load and light bidirectional axial load at the same time
6. Global unified standard dimensions for direct one-to-one aftermarket replacement and interchange
7. Reinforced riveted steel cage prevents steel ball displacement under long-term severe vibration and shock
8. Customizable precision grade, special lubricant formula and outer ring laser marking with customer logo

4. Application Scenarios

• Large heavy-duty industrial drive motors, super large ventilation cooling fans and industrial blowers
• Heavy-load long-distance conveyor rollers, heavy automatic packaging and logistics transmission machinery
• Large textile processing equipment, agricultural heavy rotary processing components
• Mine auxiliary machinery, factory heavy-duty auxiliary transmission equipment
• Medium construction machinery, large industrial ventilation and ventilation assemblies

Suitable for OEM supporting production and aftermarket maintenance of large heavy-load general industrial equipment.
