Steel Deep Groove Ball Bearing 0.276 in Bore 0.748 in OD, Pkg Qty 12

Overview

This steel deep groove ball bearing is engineered for high-speed rotational applications requiring minimal maintenance and reliable performance. Featuring a precise 0.276-inch bore and a 0.748-inch outside diameter, it ensures accurate shaft alignment within compact mechanical assemblies. The unit measures 0.236 inches in width and utilizes robust steel construction to withstand significant radial loads while supporting moderate axial forces in both directions. Designed with integral sealing on both sides, this component effectively retains lubrication and excludes contaminants, extending service life in demanding industrial environments without the need for frequent re-lubrication.

Key Features

Double-sided integral seals prevent contamination ingress and lubricant leakage High-grade steel construction provides superior load capacity and durability Optimized for high-speed rotation with minimal friction and heat generation Supports combined radial and axial loads in bidirectional applications Precision-ground raceways ensure smooth operation and reduced vibration Low maintenance design eliminates the need for regular re-greasing intervals Compact profile fits easily into space-constrained machinery designs

Applications

Electric motor shafts and spindle assemblies Automotive alternators and starter motors Conveyor system rollers and idlers Agricultural machinery gearboxes HVAC fan blades and blower wheels Power tool rotating components Textile manufacturing equipment Food processing machinery requiring sealed bearings This bearing series represents a critical component for original equipment manufacturers and maintenance teams seeking reliability in continuous-duty cycles. The standardized dimensions allow for easy replacement and integration into existing systems designed around fractional inch shaft sizes. By maintaining strict tolerances during manufacturing, each unit delivers consistent performance across varying operating temperatures and speeds. The sealed design is particularly advantageous in environments exposed to dust, moisture, or fine particulate matter, as it protects the internal rolling elements from premature wear. Users benefit from reduced downtime and lower total cost of ownership due to the extended service intervals provided by the factory-sealed lubrication system. Whether deployed in light industrial settings or heavy-duty commercial applications, this deep groove ball bearing offers a balance of strength, precision, and longevity essential for modern mechanical systems.
