MAPLE ACE UC210-32 Insert Bearing 2″ Bore, Spherical OD, R3 Triple Lip Seal with Set Screws and Lubrication Hole

Description

Product Overview

The MAPLE ACE UC21032 insert bearing is engineered for demanding power‑transmission systems where reliability and precision are paramount. Featuring a 2 inch (approximately 50 mm) bore, a spherical outer diameter that accommodates misalignment, and a high‑performance triple lip seal, this bearing delivers reduced vibration, low operational noise, and extended service intervals. Constructed from premium steel alloys and finished with a corrosion‑resistant coating, the unit meets rigorous industrial standards and is compatible with extreme temperature ranges. The design includes set screws for secure mounting and a dedicated lubrication hole that simplifies maintenance and ensures consistent oil distribution throughout the bearing life.

Usage

This insert bearing excels in a variety of heavy‑duty environments, including conveyor systems, gearboxes, motor shafts, and agricultural machinery. Its spherical outer diameter allows it to compensate for shaft misalignment, making it ideal for applications where axial and radial loads fluctuate. The triple lip seal protects internal components from dust, moisture, and contaminants, which is essential for outdoor installations, mining equipment, and high‑speed production lines. OEM manufacturers and maintenance technicians alike appreciate the ease of installation thanks to the integrated set screws and lubrication port, reducing downtime and simplifying routine servicing.
