<h2>Overview</h2>
<p>The <strong>Link-Belt PB22427H</strong> is a solid-housed, cast iron pillow block bearing featuring a spherical roller design for self-aligning operation in mechanical power transmission systems. Manufactured by Rexnord under the Link-Belt brand, this 1-11/16″ bore unit combines robust construction with proven industrial reliability. The mounting pad dimensions (7-1/8″ overall length, 2-1/2″ width) and standard 1/2″ bolt holes make it ideal for drop-in retrofits and new equipment builds.</p>
<h2>Key Features</h2>
<ul>
<li><strong>Spherical Roller Design:</strong> Self-aligning double-row rollers accommodate up to ±2° of angular misalignment, reducing load on shaft and bearing surfaces</li>
<li><strong>Cast Iron Housing:</strong> Durable 2-bolt solid-housed pillow block for stable, vibration-resistant mounting</li>
<li><strong>Single Setscrew Locking Collar:</strong> Secure, tool-free shaft locking mechanism; no special fixtures required</li>
<li><strong>Clearance Seal:</strong> Labyrinth-type bearing protection with minimal friction and temperature rise</li>
<li><strong>High Load Capacity:</strong> 24,700 lbf dynamic / 28,700 lbf static load ratings ensure reliable operation under demanding conditions</li>
</ul>
