UCFL206-20 QJZ Flange Mount Ball Bearing Unit, 5-13/16in Height

Description

Product Overview

The UCFL206-20 from QJZ is a precision‑engineered flange‑mount ball bearing unit designed for demanding power transmission applications. Constructed with a solid cast iron housing, the unit offers exceptional rigidity and resistance to wear, ensuring consistent performance even under heavy radial loads. The insert bearing UC206-20 provides a high‑quality rolling element assembly that reduces friction and extends service life, while the 5‑13/16 in flange height delivers ample clearance for a variety of mounting configurations.

With a 1‑1/4 in (31.75 mm) bore shaft diameter, this bearing unit fits standard shafts commonly found in industrial gearboxes, conveyors, and pump assemblies. The set‑screw locking mechanism secures the unit to the flange without the need for additional fasteners, simplifying installation and maintenance. The design adheres to normal‑duty specifications, making it suitable for continuous operation in environments where reliability and uptime are critical.

Dimensional accuracy is a hallmark of the UCFL206-20. The flange width of 3‑1/8 in (79.375 mm) and overall height of 5‑13/16 in (147.637 mm) provide a stable platform that distributes loads evenly across the mounting surface. This geometry helps to minimize vibration and noise, contributing to smoother operation of the surrounding machinery. The unit’s robust construction also offers excellent resistance to corrosion and thermal expansion, further enhancing its durability in harsh industrial settings.

Engineered for compatibility with a broad range of industrial standards, the UCFL206-20 meets the requirements of ISO and ANSI bearing specifications. Its interchangeable insert bearing design allows for easy replacement of the rolling elements, reducing downtime and maintenance costs. The unit’s compact footprint ensures that it can be integrated into space‑constrained installations without sacrificing performance.

Overall, the UCFL206-20 delivers a balanced combination of strength, precision, and ease of use. Whether used in heavy‑duty conveyor drives, high‑speed motor shafts, or precision machining equipment, this bearing unit provides the reliability and performance that modern industrial operations demand.

Usage

This flange‑mount bearing is ideally suited for applications such as gear reducers, motor shafts, pump housings, and conveyor rollers where a secure, load‑bearing connection is required. Its cast iron housing offers excellent damping properties, making it a preferred choice for equipment that operates at high speeds or under variable load conditions. The unit can be employed in both indoor factory environments and outdoor installations that are protected from direct exposure to the elements.

Installation is straightforward: the set‑screw locking feature allows technicians to align the bearing with the mounting flange and secure it in place using a standard hex wrench. This reduces the time required for assembly and eliminates the need for additional fastening hardware. The insert bearing can be serviced independently, enabling quick replacement of worn components without disassembling the entire system.

In addition to traditional industrial uses, the UCFL206-20 is compatible with custom machinery designs that require a reliable bearing solution with a specific flange height. Its versatility makes it a valuable component for OEMs and system integrators who need to meet precise engineering specifications while maintaining cost‑effectiveness.
