6314-2RS1/C3 Deep Groove Ball Bearing 70x150x35mm Double 2RS1 Rubber Seal C3 Clearance Bearing

1. Product Overview

6314-2RS1/C3 single row deep groove ball bearing, standard metric dimension 70×150×35mm.
Code Definition

• 6314: Large heavy-duty deep groove ball bearing, equipped with thickened steel balls for superior radial load capacity
• 2RS1: Double-sided contact rubber lip seal, fully blocks dust, moisture, metal scraps and fine abrasive particles
• C3: Widened internal radial clearance, specially designed for high-speed and high-temperature working conditions

Classic deep groove raceway can bear radial load and slight bidirectional axial load simultaneously. Dual contact rubber seals lock internal lubricant and isolate external pollutants effectively. Pre-filled high-temperature anti-oxidation grease, which avoids grease thinning, volatilization and dry friction under long-time continuous temperature rise. Widely used for large heavy-duty industrial drive motors, large cooling blowers, heavy conveyor rollers, heavy packaging equipment, mine auxiliary machinery and large heavy-load transmission assemblies.

2. Technical Specifications

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

3. Core Advantages

1. Standard C3 enlarged clearance eliminates bearing seizure caused by thermal expansion during long high-speed heavy-load operation
2. Double 2RS1 contact rubber seals fully block dust, water mist and tiny metal debris to extend service life
3. High-temperature anti-oxidation grease reduces grease loss and prevents dry burning under sustained heating
4. Thickened super-finished steel balls provide ultra-high heavy load capacity, low friction, quiet and stable rotation
5. Universal deep groove structure bears radial load and light bidirectional axial load at the same time
6. Global unified standard dimensions for direct one-to-one aftermarket interchange and replacement
7. Reinforced riveted steel cage prevents steel ball displacement under long-term severe vibration and impact
8. Customizable precision grade, special lubricant and outer ring laser logo marking

4. Application Scenarios

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