Design Features of 311 Bearing

311 Bearing is designed to offer enhanced performance in specific applications. It features filling slots in both the inner and outer rings to accommodate more balls. 311 bore dia is 55 mm. Its out dia is 120 mm. 311 width is 29 mm. This bearing is ideal for specialized applications requiring higher radial load endurance.

 

What Benefits Can 311 Bearing Provide?

Enhanced Radial Load Capacity: Accommodates more balls for greater load-handling.

• Versatile Configurations: Available open or with shields, and with or without a snap ring groove.
• Simplified Mounting: Snap ring option allows for quicker and easier installation.
• Customizable None: Various grease options to match different operating conditions.
• Lower Speed Limitations: Best suited for applications where high-speed operation is not critical.

 

What Can 311 Bearing Be Used for?

311 Bearing is ideal for a variety of applications that require higher radial load capacity but don't demand high-speed performance. Here are some of the common uses:

• Gearboxes: Useful in gear reduction units that require high load capacity but operate at moderate speeds.
• Pumps: Employed in heavy-duty water and oil pumps requiring robust bearings to handle the high radial loads.
• Industrial Fans and Blowers: Ideal for large fans and blowers that move high volumes of air but don't require extremely high speeds.
• Conveyor Systems: Useful in belt or roller conveyors where they can handle the radial loads produced by the weight of the goods being moved.
