<h2>Overview</h2>
<p>The <strong>CR 11340 oil seal</strong> is a precision-engineered radial shaft seal manufactured by Chicago Rawhide (SKF). This CRW1 design is built for small-bore applications requiring robust sealing performance in machinery and rotating equipment. The seal’s construction includes a single steel case with wave lip and carbon steel garter spring for consistent radial load and reliable protection against fluid leakage.</p>
<h2>Key Features</h2>
<ul>
<li>Type CRW1 single-lip radial design with molded sealing edge</li>
<li>Nitrile (NBR) rubber lip material for wide fluid compatibility</li>
<li>Steel case with wave lip and carbon steel garter spring for precise contact pressure</li>
<li>Operating temperature range: -40°F to 212°F (-40°C to 100°C)</li>
<li>Single-sealed design with external diameter lip protection</li>
</ul>
<h2>Technical Specifications</h2>

<li>Width (W): 0.256″</li>
<li>Seal Type: Single-lip, radial shaft seal</li>
<li>Lip Material: Nitrile rubber (NBR)</li>
<li>Case Material: Steel</li>
<li>Cross-Section: R</li>
<li>Design Type: CRW1</li>
<li>Temperature Range: -40°F to 212°F</li>
</ul>
<h2>Typical Applications</h2>
<p>The CR 11340 radial seal is commonly used in small-bore rotating equipment, including pumps, motors, gearboxes, and industrial machinery. The nitrile lip material makes it suitable for applications using mineral oils, synthetic fluids, and water-resistant compounds. The sealed design prevents contaminant ingress while containing lubrication fluid in confined spaces.</p>
