Steel Deep Groove Ball Bearing 2.17 in Bore 5.51 in OD, Pkg Qty 2

Overview

This industrial-grade deep groove ball bearing is engineered to deliver exceptional performance in heavy-duty mechanical systems. Constructed from high-quality hardened steel, the unit provides superior resistance to wear, deformation, and fatigue under continuous operation. The design facilitates precise shaft alignment while supporting significant radial loads and moderate axial loads in both directions. With robust dimensional stability, this component ensures smooth rotation and minimal friction, making it an ideal choice for demanding environments where reliability and extended service life are critical. The package includes two units to support immediate maintenance or replacement needs.

Key Features

Hardened steel construction for maximum durability and load capacity Precision-ground raceways ensure smooth operation and reduced vibration Supports high radial loads alongside moderate axial loads in both directions Optimized internal geometry minimizes friction and heat generation Sealed design options available to protect against contaminants and retain lubrication Compatible with standard industrial shafting and housing configurations Low maintenance requirements reduce operational downtime and total cost of ownership

Applications

Heavy-duty electric motors and generators Industrial gearboxes and speed reducers Conveyor system drive rollers Agricultural machinery and harvesting equipment Pump assemblies and fluid handling systems Machine tool spindles and rotating fixtures Mining and construction equipment drivetrains HVAC blower wheels and large fans Installation and Maintenance Proper installation requires clean working conditions and the use of appropriate pressing tools to avoid damaging the raceways. The bearing should be mounted with a tight fit on the shaft and a loose fit in the housing to accommodate thermal expansion during operation. Regular inspection intervals are recommended to check for signs of lubrication breakdown, contamination, or unusual noise. When operated within specified load and speed limits, this bearing delivers consistent performance with minimal need for intervention. Lubrication type and frequency should be determined based on specific operating speeds and environmental conditions to maximize component lifespan.
