Overview

This industrial-grade deep groove ball bearing is engineered to deliver reliable rotational support for demanding mechanical systems. Constructed from high-quality steel, the unit provides exceptional load capacity and resistance to deformation under significant stress. The design features a precise 1.77-inch bore diameter and a 3.94-inch outside diameter, with a width of 0.98 inches to ensure compatibility with standard housing configurations. Built for longevity, this bearing incorporates dual metal shields and optimized internal clearance to maintain performance in challenging operating environments.

Key Features

Dual metal shields effectively retain lubrication while excluding dust, dirt, and other contaminants C3 internal clearance designed for optimal performance in elevated temperature conditions High-load steel construction resists deformation under heavy radial and axial stresses Precision-machined raceways ensure smooth rotation and reduced friction Extended service life reduces maintenance intervals and operational downtime Compatible with a wide range of industrial motors, gearboxes, and conveyor systems

Material

Steel Internal Clearance: C3 Shield Type: Dual Metal Shields (2Z) Package Quantity: 2 units Load Capacity: High radial and moderate axial loads Temperature Suitability: Elevated temperature environments

Applications

Electric motor shafts requiring high-speed rotation and thermal stability Industrial gearbox assemblies subject to continuous heavy loads Conveyor system rollers in manufacturing and processing facilities Agricultural machinery exposed to dusty or dirty operating conditions Pump and compressor components needing reliable sealing against contaminants HVAC fan assemblies where consistent performance at varying temperatures is critical Automotive transmission systems requiring durable rotational support Textile machinery where lint and fiber exclusion are necessary for bearing longevity This component serves as a critical element in maintaining the efficiency and reliability of rotating equipment across multiple sectors. The combination of robust steel materials, protective shielding, and specialized internal clearance makes it an ideal choice for applications where standard bearings may fail due to heat buildup or contaminant ingress. By ensuring proper alignment and smooth operation, this bearing helps maximize the uptime of essential industrial assets. The package includes two units, allowing for immediate replacement or stocking for scheduled maintenance programs.

Frequently Asked Questions

What are the precise dimensional specifications for this steel deep groove ball bearing?
This bearing features a bore diameter of 1.77 inches and an outside diameter of 3.94 inches, with a total width of 0.98 inches. Constructed from durable steel, it is designed to fit standard shafts requiring these specific imperial measurements.
In which industrial applications is the C3 clearance and 2Z shielding most beneficial?
The C3 internal clearance allows for optimal performance in high-speed applications or environments where operating temperatures exceed standard ranges up to several hundred degrees Fahrenheit. The 2Z metal shields on both sides effectively retain lubrication while excluding larger debris, making it ideal for electric motors, gearboxes, and agricultural machinery.
How is this product packaged and what is the minimum order quantity?
Each package contains two units of the 6309-2Z/C3WT bearing, ensuring you have immediate spares for maintenance or dual-installation projects. Orders are fulfilled based on these pack sizes, so please adjust your requisition quantities in multiples of two to match our shipping standards.
