Steel Deep Groove Ball Bearing 0.47in Bore 1.26in OD, Pkg Qty 25

Overview

This industrial-grade deep groove ball bearing is engineered for high-speed rotational applications requiring precise radial support and long-term reliability. Constructed from hardened steel, the unit features a 0.47-inch bore diameter, a 1.26-inch outside diameter, and a width of 0.39 inches. The design incorporates C3 internal clearance, which is specifically calibrated to accommodate thermal expansion and minor shaft misalignment, ensuring consistent performance even under fluctuating operational temperatures. Dual non-contacting rubber seals provide robust protection against dust, moisture, and other contaminants while maintaining low friction torque for energy-efficient operation. This component is ideal for electric motors, power transmission systems, and general industrial machinery where durability and smooth rotation are critical.

Key Features

Hardened steel construction ensures high load capacity and extended service life C3 internal clearance accommodates thermal growth and slight misalignment Dual non-contacting rubber seals protect against contamination with minimal friction Optimized for high-speed rotational environments up to standard industrial limits Precision-ground raceways reduce vibration and noise during operation Standardized dimensions allow for easy replacement and interoperability

Applications

Electric motor assemblies requiring high-speed precision Power transmission systems in manufacturing equipment Industrial pumps and fans operating in variable temperature conditions Conveyor belt rollers and material handling machinery Automotive alternators and starter motors Agricultural equipment gearboxes and drive shafts HVAC blower motors and ventilation systems Performance Notes The C3 clearance specification makes this bearing particularly suitable for applications where heat generation is expected, as it prevents premature failure due to internal binding. The sealed design eliminates the need for frequent relubrication in many standard environments, reducing maintenance downtime. When installed correctly with appropriate fits, this bearing delivers stable performance across a wide range of speeds and loads. The package contains 25 individual units, providing cost-effective inventory solutions for large-scale maintenance operations or original equipment manufacturing lines. Users should ensure shaft and housing tolerances align with standard ISO recommendations for deep groove ball bearings to maximize service life and performance efficiency.
