UC206-20K 1-1/4″ Bore Set Screw Lock Insert Bearing – Miao Machinery

Description

Product Overview

The UC206-20K insert bearing from Miao Machinery is engineered for high‑performance power transmission in demanding industrial environments. With a precise 1‑1/4″ bore and a robust 2‑31/64″ outer diameter, this bearing fits seamlessly into shafts that require a secure lock screw mechanism. The spherical insert provides self‑aligning capability, allowing the bearing to accommodate minor misalignments while maintaining smooth rotational motion. Constructed from hardened steel, the bearing resists wear, corrosion, and fatigue, delivering a long service life even under heavy radial and axial loads. The compact design, measuring 1‑1/2″ in height, enables installation in confined spaces without sacrificing strength. Each unit is supplied with a set screw that locks the bearing in place, preventing axial drift during operation. The product meets ISO standards for insert bearings and has earned a top‑10 ranking in its category on major e‑commerce platforms, reflecting both its reliability and popularity among engineers and maintenance professionals. The UC206-20K is compatible with a wide range of machinery, including gearboxes, conveyors, and motor assemblies, making it a versatile choice for manufacturers seeking to improve efficiency and reduce downtime.

Usage

Designed for versatility, the UC206-20K insert bearing excels in applications where precise alignment and secure fixation are critical. It is ideal for gearboxes that operate at high speeds, where the lock screw prevents axial movement that could otherwise cause gear tooth wear. In conveyor systems, the bearing supports shafts that experience frequent start‑stop cycles, delivering consistent performance without overheating. Maintenance technicians appreciate the ease of installation: the bearing can be pressed into a pre‑drilled bore, and the set screw tightened with a standard hex key, eliminating the need for specialized tools. Its spherical insert adapts to slight shaft deflection, reducing vibration and extending the life of adjacent components. The bearing also performs well in harsh environments such as chemical processing plants, where its corrosion‑resistant steel construction protects against moisture and aggressive fluids. Whether retrofitting older equipment or integrating into new designs, the UC206-20K provides a reliable solution that minimizes downtime and maintenance costs.

FAQ

What size shaft can the UC206-20K bearing accommodate?

The bearing is designed for a 1‑1/4″ (31.75 mm) bore, making it compatible with shafts that match this diameter. It is important to verify the shaft’s tolerance range before installation to ensure a proper fit and optimal performance.

How does the lock screw mechanism work?

The lock screw is threaded into the bearing’s outer race and, when tightened, presses against the shaft to lock the bearing in place. This prevents any axial movement during operation, which is especially useful in high‑speed or high‑torque applications where bearing shift could cause premature wear.

Can the bearing be used in corrosive environments?

Yes. The UC206-20K is fabricated from hardened steel that has been treated to resist corrosion. While it performs well in most industrial settings, for extremely aggressive chemicals it is recommended to apply a compatible protective coating or sealant for added longevity.

Is special tooling required for installation?

No special tooling is needed. The bearing can be pressed into a correctly sized bore using a standard bearing press or a simple hammer and a suitable driver. The lock screw is tightened with a standard hex key, making the installation process quick and straightforward.

What warranty does Miao Machinery provide?

Miao Machinery offers a 100% satisfaction guarantee on the UC206-20K bearing. If the product does not meet the expected performance criteria, customers can contact our support team for a replacement or refund, subject to the terms outlined in the warranty policy.
