Steel Deep Groove Ball Bearing 1.57in Bore 3.15in OD 0.71in L, Pkg Qty 6

Overview

This industrial-grade deep groove ball bearing is engineered to deliver reliable rotational support in high-load mechanical systems. Constructed from hardened steel, the unit offers exceptional resistance to wear, deformation, and fatigue under continuous operation. The design features a precise 1.57-inch bore diameter and a 3.15-inch outside diameter, with a compact width of 0.71 inches to fit standard housing configurations. Integrated sealing mechanisms effectively retain lubrication while excluding dust, moisture, and other contaminants, significantly extending service life in demanding environments. Sold in packages of six, these bearings provide consistent performance for applications requiring precise alignment and robust load capacity.

Key Features

Hardened steel construction for maximum durability and load-bearing capability Integrated dual seals to retain grease and exclude contaminants Precision-ground raceways for smooth rotation and reduced friction Optimized for both radial and moderate axial load conditions Low maintenance requirements for extended operational uptime Sold in convenient packs of six for fleet replacements and inventory management

Material

Hardened Steel Seal Type: Double Sealed (Non-Contact) Load Capacity: High Radial and Moderate Axial Package Quantity: 6 units

Applications

Electric motor shafts and armatures Industrial gearbox assemblies Conveyor system rollers and pulleys Agricultural machinery drive trains HVAC fan motors and blowers Pump housings and fluid handling equipment Automotive alternators and starter motors Performance and Reliability The geometric precision of this bearing ensures minimal vibration and noise during high-speed rotation, making it ideal for sensitive equipment. The hardened steel material undergoes rigorous heat treatment to achieve optimal surface hardness, preventing brinelling and surface cracking even under shock loads. The sealed design eliminates the need for frequent relubrication, reducing total cost of ownership and minimizing downtime for maintenance crews. Each unit in the six-pack is manufactured to strict tolerances, ensuring interchangeability and ease of installation across various machinery platforms. Whether used in manufacturing lines, processing facilities, or heavy equipment, this bearing provides the structural integrity necessary for uninterrupted production cycles.
