F3S223E Flange Unit, 4 Bolt Holes, Intermediate-Duty, Relubricatable, Non-Expansion, Cast Iron, Spring Locking Collar, Inch, 1-7/16″ Bore Diameter

Description

Product Overview

The Link-Belt Flange Unit F3S223E is engineered for industrial power transmission environments where reliability and ease of maintenance are paramount. Constructed from high‑strength cast iron, the housing delivers exceptional rigidity and vibration damping, extending the service life of connected machinery. A spring‑locking collar secures the bearing to the shaft without the need for additional fasteners, simplifying installation and reducing downtime.

The integrated double‑sealed ball bearing is relubricatable, allowing technicians to replenish grease through the built‑in fitting, which prolongs bearing life and maintains optimal performance under moderate radial and thrust loads. Molded lip seals on both sides of the bearing protect against dust, moisture, and other contaminants, ensuring consistent operation even in harsh environments.

Usage

This flange unit excels in a variety of applications, including conveyor systems, gearboxes, and pump assemblies where intermediate‑duty loads are common. Its 1‑7/16″ bore diameter fits standard shafts, making it a versatile choice for retrofits and new equipment designs. The robust iron construction tolerates temperature fluctuations and mechanical shock, making it suitable for manufacturing floors, processing plants, and heavy‑duty automation lines.

Engineers and maintenance personnel appreciate the ease of relubrication, which can be performed without disassembly, reducing labor costs and equipment downtime. The spring‑locking collar provides a secure, repeatable fit, ensuring that the bearing remains properly aligned during operation, even under variable load conditions.

FAQ

What size shaft does this flange unit fit?

The unit is designed for a 1‑7/16″ bore diameter, matching standard shaft sizes used in many industrial applications.

Can the bearing be re‑greased without disassembly?

Yes, the housing includes a grease fitting that allows you to add lubricant directly to the bearing without removing the unit from the equipment.

What load capacities are supported?

The double‑sealed ball bearing is rated for moderate radial loads and light to moderate thrust loads, making it ideal for intermediate‑duty applications.

Is the unit suitable for high‑temperature environments?

While the cast‑iron housing can tolerate typical industrial temperature ranges, extreme heat beyond the material’s specifications should be avoided.

How does the spring‑locking collar differ from traditional set‑screws?

The spring‑locking collar provides a repeatable, vibration‑resistant connection without the need for set‑screws, reducing the risk of loosening over time.

In summary, the Link‑Belt Flange Unit F3S223E combines robust construction, easy maintenance, and reliable performance to meet the demanding needs of modern industrial power transmission systems.
