UC207 Insert Bearing QJZ – 1-3/8 in Bore, Double Sealed, Relubricable

Description

Product Overview

The UC207 insert bearing by QJZ is a precision‑engineered component designed to meet the rigorous demands of modern power transmission systems. With a 1‑3/8 inch (35 mm) bore and a 2.835 inch (72 mm) outer diameter, this bearing fits a wide range of industrial shafts while delivering smooth rotational motion. Its double‑sealing system protects the internal rolling elements from contaminants such as dust, moisture, and chemical exposure, extending service life and reducing downtime. The relubricable feature allows maintenance personnel to replenish lubrication without disassembly, ensuring consistent performance over the bearing’s operational lifespan. Constructed from high‑grade steel and finished to exacting tolerances, the UC207 offers a balance of strength, durability, and precision that is essential for heavy‑duty applications.

Beyond its robust construction, the bearing incorporates a set‑screw locking collar that secures the unit to the shaft, preventing axial movement under high‑load conditions. This design element simplifies installation while providing a reliable lock‑in place mechanism that resists vibration and shock. The outer ring width of 0.787 inches (20 mm) contributes to a compact profile, allowing the bearing to be integrated into tight spaces without sacrificing load‑carrying capacity. The UC207 is also compatible with standard lubrication regimes, making it a versatile choice for facilities that follow established maintenance protocols.

Overall, the UC207 insert bearing delivers a combination of high performance, ease of service, and adaptability that makes it a preferred solution for manufacturers, equipment integrators, and maintenance engineers seeking dependable motion control components.

Usage

This bearing excels in environments where reliability and precision are non‑negotiable. Typical applications include conveyor systems, gearboxes, motor shafts, and heavy‑duty pumps that operate under continuous or intermittent loads. Its double‑sealed design is especially valuable in dusty manufacturing floors, humid processing plants, and chemical handling facilities where exposure to contaminants can quickly degrade unprotected bearings. The relubricable capability ensures that routine maintenance can be performed quickly, minimizing equipment downtime and extending the interval between major overhauls.

Engineers often select the UC207 for high‑speed rotational equipment that demands consistent torque transmission and minimal vibration. The set‑screw locking collar provides added security for applications subject to sudden torque spikes, such as crushers, mixers, and industrial fans. Additionally, the bearing’s dimensions make it suitable for retrofitting older machinery that requires an upgrade to modern sealing and lubrication standards without extensive redesign.

When integrated into a system, the UC207 contributes to overall equipment efficiency by reducing friction losses and heat generation. This translates into lower energy consumption and improved operational stability, which are critical factors for facilities aiming to optimize production costs and meet sustainability targets.

FAQ

What size shaft can the UC207 bearing accommodate?

The UC207 is designed for a bore diameter of 1‑3/8 inches (35 mm), making it compatible with shafts that match this exact dimension. It is essential to verify the shaft size before installation to ensure a proper fit.

How often should the bearing be relubricated?

Relubrication intervals depend on operating conditions such as load, speed, and environmental factors. In typical industrial settings, a relubrication schedule of every 12‑18 months is recommended, but more frequent maintenance may be required in harsher environments.

Can the bearing be used in high‑temperature applications?

Yes, the UC207 bearing is rated for temperatures up to 200 °F (93 °C) when used with appropriate high‑temperature lubricants. For temperatures exceeding this range, a specialized bearing variant should be considered.

Is the set‑screw locking collar adjustable?

The set‑screw locking collar is designed to be tightened to a specific torque value to secure the bearing. While it is not adjustable for different positions, it can be re‑tightened if needed during maintenance or after bearing replacement.

What warranty does QJZ provide for the UC207 bearing?

QJZ offers a limited one‑year warranty covering manufacturing defects and material failures under normal operating conditions. Warranty claims are processed through our customer service team, which will guide you through the return and replacement process.
