Steel Deep Groove Ball Bearing 0.39 in Bore 0.87 in OD, Pkg Qty 8

Overview

This steel deep groove ball bearing is engineered for high-speed rotational applications requiring minimal maintenance and reliable performance. Featuring a 0.39-inch bore diameter and a 0.87-inch outside diameter, the unit measures 0.24 inches in width to fit compact assemblies where space is limited. The robust steel construction ensures durability under significant radial loads while maintaining precise shaft alignment. Designed with dual metal shields, this bearing effectively retains lubrication and excludes dust, dirt, and other contaminants, extending service life in demanding industrial environments without requiring frequent re-lubrication.

Key Features

Dual metal shields provide superior protection against contamination High-grade steel construction supports heavy radial loads Optimized for high-speed rotational operations Compact 0.24-inch width fits tight mechanical spaces Pre-lubricated design reduces maintenance intervals Precision ground raceways ensure smooth operation and low noise Consistent performance across varying temperature ranges

Applications

Electric motor assemblies Conveyor system rollers Agricultural machinery components Automotive alternators and starters Industrial gearboxes Pump shafts and fans Power tools and handheld equipment HVAC blower wheels This component serves as a critical element in rotating machinery where reliability and longevity are paramount. The deep groove geometry allows the bearing to handle both radial and moderate axial loads, making it versatile for various mechanical configurations. The metal shielding offers a balance between protection and speed capability, outperforming rubber-sealed variants in high-temperature or high-RPM scenarios while still keeping internal lubricant intact. Each package contains eight units, facilitating efficient inventory management for production lines and maintenance teams. The standardized dimensions ensure interchangeability with existing systems designed for this specific bore and outer diameter profile. By minimizing friction and wear, these bearings contribute to overall energy efficiency and reduced downtime in continuous operation settings.
