6319-2RS1/C3 Deep Groove Ball Bearing 95x200x45mm Double 2RS1 Rubber Seal C3 Clearance Bearing

1. Product Overview

6319-2RS1/C3 single row deep groove ball bearing, standard metric dimension 95×200×45mm.

Code Definition

• 6319: Extra large heavy-duty deep groove ball bearing, equipped with extra thickened steel balls to deliver ultra-high radial load bearing capacity
• 2RS1: Double-sided contact rubber lip seal, fully isolates dust, mud, moisture, metal scraps and all types of fine abrasive particles
• C3: Widened internal radial clearance, specially engineered for heavy-load, high-speed and high-temperature working environments to eliminate thermal expansion seizure risk

Classic deep groove raceway structure can bear radial load and slight bidirectional axial load simultaneously. Dual contact rubber seals tightly lock internal lubricating grease and block external pollutants effectively. Pre-filled premium high-temperature anti-oxidation grease, which prevents grease thinning, volatilization and dry friction under long-time continuous heat buildup. Widely applied to extra large heavy-duty industrial drive motors, oversized industrial cooling blowers, heavy long-distance conveyor rollers, heavy packaging machinery, mining auxiliary equipment, medium & large construction machinery and heavy general transmission assemblies.

2. Technical Specifications

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

3. Core Advantages

1. Standard C3 enlarged clearance avoids bearing locking and seizure caused by thermal expansion during long-time high-speed heavy-duty continuous operation
2. Double 2RS1 contact rubber seals form dual-layer protection against dust, water mist and tiny metal debris to greatly extend bearing service life
3. Matching high-temperature anti-oxidation grease reduces grease loss and eliminates dry burning failure under sustained long-term heating
4. Extra thickened super-finished steel balls provide ultra-high heavy load capacity, low friction coefficient, stable and quiet rotation performance
5. Universal deep groove design bears radial load and light bidirectional axial load at the same time with wide industry compatibility
6. Globally unified international standard dimensions for direct one-to-one interchange and aftermarket replacement
7. Reinforced riveted steel cage effectively prevents steel ball displacement under long-term severe vibration and impact loads
8. Support customized precision grade, special lubricant formula and outer ring laser marking with exclusive customer brand logos

4. Application Scenarios

• Extra large heavy-duty industrial drive motors, oversized ventilation cooling fans and industrial blowers
• Heavy-load long-distance conveyor rollers, heavy automatic packaging and logistics transmission machinery
• Large textile processing equipment, heavy rotary core components for large agricultural machinery
• Mining auxiliary machinery, heavy-duty auxiliary transmission equipment for large factories
• Medium & large construction machinery, large industrial ventilation and ventilation assemblies

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