Steel Deep Groove Ball Bearing 1.38in Bore 3.15in OD for Industrial, Pkg Qty 8

Overview

This high-performance deep groove ball bearing is engineered to deliver exceptional reliability in demanding industrial environments. Constructed from premium-grade steel, it provides robust rotational support for heavy-duty machinery while minimizing maintenance requirements. The unit features a precise 1.38-inch bore diameter, a 3.15-inch outside diameter, and a width of 0.83 inches, ensuring seamless integration into standard equipment housings. Designed with double metal shields, this bearing effectively excludes contaminants such as dust and debris while retaining essential lubrication, making it ideal for operations where cleanliness and longevity are critical. Its optimized internal geometry supports high radial loads and moderate axial loads in both directions, maintaining smooth operation under continuous stress.

Key Features

Double metal shield design for superior contamination protection High-load capacity steel construction for extended service life Precision-ground raceways for reduced friction and heat generation C3 internal clearance rating to accommodate thermal expansion Sealed-for-life lubrication eliminates the need for routine re-greasing Compatible with high-speed rotational applications Resistant to wear and deformation under heavy operational stress

Specifications

Bore Diameter: 1.38 in Outside Diameter: 3.15 in Width: 0.83 in

Material

High-Carbon Chrome Steel Shield Type: Double Metal Shield (2Z) Internal Clearance: C3 Load Capacity: High Radial and Moderate Axial Pack Quantity: 8 units per package

Applications

Electric motor shafts and spindles Industrial gearbox assemblies Conveyor system rollers and pulleys Agricultural machinery drive trains HVAC fan motors and blowers Pump impeller supports Machine tool components Automotive alternators and starters This component serves as a critical replacement or upgrade part for a wide range of mechanical systems requiring precise alignment and durable performance. The C3 clearance specification allows the bearing to operate efficiently in environments with elevated temperatures or where slight misalignment may occur during installation. By utilizing hardened steel races and precision-machined balls, the unit ensures minimal vibration and noise levels, contributing to overall equipment efficiency. The double shielding mechanism offers a balanced solution between the full protection of sealed units and the high-speed capabilities of open bearings. Whether deployed in manufacturing plants, processing facilities, or transportation infrastructure, this bearing delivers consistent torque transmission and rotational stability. The package includes eight individual units, providing cost-effective inventory solutions for maintenance teams managing multiple assets. Proper installation within specified tolerance ranges will maximize the operational lifespan and prevent premature failure due to mounting errors.
