Steel Deep Groove Ball Bearing 1.18in Bore 2.44in OD 0.63in L, Pkg Qty 6

Overview

This industrial-grade deep groove ball bearing is engineered for high-speed mechanical applications requiring precise rotational stability and robust load management. Constructed from premium steel, the unit features a 1.18-inch bore diameter, a 2.44-inch outside diameter, and a width of 0.63 inches. The design incorporates C4 internal clearance, which is specifically calibrated to accommodate significant thermal expansion during operation in demanding environments. Dual metal shields provide effective protection against dust and debris ingress while maintaining low friction coefficients for optimal energy efficiency. These bearings are manufactured to strict tolerances to ensure minimal vibration and noise, making them ideal for continuous duty cycles where reliability is paramount.

Key Features

C4 internal clearance optimized for high-temperature operational stability Dual metal shield configuration (2Z) for superior contamination resistance Premium steel construction ensures high radial load capacity Precision-ground raceways reduce friction and heat generation Designed for high rotational speeds without compromising structural integrity Extended service life reduces maintenance intervals and total cost of ownership Consistent performance under heavy vibrational stress

Specifications

Material

Steel Internal Clearance Class: C4 Shield Type: Dual Metal (2Z) Load Type: Radial and moderate Axial Package Quantity: 6 units

Applications

Electric motor shafts and spindles Industrial gearbox assemblies Conveyor system rollers and pulleys HVAC blower wheels and fans Agricultural machinery drive trains Pump impellers and compressors Machine tool applications Operational Notes The C4 clearance specification indicates that this bearing is designed with greater internal space than standard models, allowing components to expand due to heat without causing preload issues or seizure. This makes the unit particularly suitable for applications involving rapid speed changes or elevated ambient temperatures. The metal shields offer a balanced approach to sealing, providing better protection than open bearings while generating less drag than rubber-sealed variants, thus preserving maximum rotational speed capabilities. Users should ensure proper alignment during installation to prevent premature wear and maximize the rated service life. Regular lubrication schedules should be followed based on specific operating conditions, although many units come pre-lubricated for immediate deployment. The package contains six identical units to support bulk replacement projects or multi-point maintenance routines, ensuring consistency across machinery fleets.
