6317-2RS1/C3 Deep Groove Ball Bearing 85x180x41mm Double 2RS1 Rubber Seal C3 Clearance Bearing

1. Product Overview

6317-2RS1/C3 single row deep groove ball bearing, standard metric dimension 85×180×41mm.

Code Definition

• 6317: Extra large heavy-duty deep groove ball bearing, fitted with thickened steel balls for superior radial load capacity
• 2RS1: Double-sided contact rubber lip seal, fully blocks dust, moisture, mud, metal scraps and fine abrasive particles
• C3: Enlarged internal radial clearance, designed for high-speed, heavy-load and high-temperature working environments to avoid thermal expansion seizure

Classic deep groove raceway supports radial loads and minor bidirectional axial loads simultaneously. Dual contact rubber seals lock internal lubricating grease and isolate external contaminants effectively. Pre-filled premium high-temperature anti-oxidation grease to prevent grease thinning, volatilization and dry friction under long continuous heat buildup. Widely used in extra large heavy-duty industrial drive motors, oversized cooling blowers, heavy long-distance conveyor rollers, heavy packaging equipment, mining auxiliary machines, construction machinery and large heavy-load 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 eliminates bearing locking caused by thermal expansion during long 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 extend service life greatly
3. Matched high-temperature anti-oxidation grease reduces grease loss and prevents dry burning failure under sustained heating
4. Thickened super-finished steel balls deliver ultra-high heavy load capacity, low friction, stable and quiet rotation performance
5. Universal deep groove structure bears radial load and light bidirectional axial load at the same time with wide compatibility
6. Globally unified international standard dimensions for direct one-to-one interchange and aftermarket replacement
7. Reinforced riveted steel cage avoids steel ball displacement under long-term severe vibration and impact loads
8. Customizable precision grade, special lubricant formula and outer ring laser marking with exclusive customer 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 parts for agricultural machinery
• Mining auxiliary machinery, heavy auxiliary transmission equipment for factories
• Medium & large construction machinery, large industrial ventilation assemblies

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