STANDARD-TEMP VS. HIGH-TEMP CLUTCH PILOT BEARINGS: WHAT¡¯S THE DIFFERENCE?
<p style="text-align: center;"><img src="/ueditor/php/upload/image/20221123/1669194392139892.png" title="1669194392139892.png" alt="4.png"/></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">When replacing a heavy-duty <a href="http://www.unim-inc.com/products/Clutch-Release-Bearing/8.html" target="_blank" style="color: rgb(0, 112, 192); text-decoration: underline;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px; color: rgb(0, 112, 192);"><strong>clutch pilot bearing</strong></span></a>, there are a few options to consider. You should always follow the OEM recommendations as they will require either standard- or high-temperature bearing, and that difference between the two is extremely important.</span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;"><br/></span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">While clutch pilot bearings are often thought of as a relatively simple deep groove ball bearing, they are actually highly-engineered and purpose built for demanding applications. Major differences between Standard and High Temp bearings is the use of different greases and seal materials, as you can see here:</span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">Standard-temp clutch pilot bearings</span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">Grease: Polyrex EM Grease ¨C Temp range of -13¡ãF to 338¡ãF (-25¡ãC to 170¡ãC)<br/>Seal: Full Contact Nitrile Seal ¨C Temp range of -15¡ãF to 225¡ãF (-26¡ãC to 107¡ãC)</span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;"><br/></span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">High-temp clutch pilot bearings</span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">Grease: Krytox GPL225 Grease ¨C Temp range of -40¡ãF to 428¡ãF (-40¡ãC to 220¡ãC)<br/>Seal: Full Contact Viton Seal ¨C Temp range of -40¡ãF to 425¡ãF (-40¡ãC to 218¡ãC)</span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;"><br/></span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">You¡¯ll usually find high-temp bearings in heavy-duty applications. And you¡¯ll want to note if the clutch pilot bearing you¡¯re servicing also has an integrated snap ring.</span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;"><br/></span></p><p style="text-align: justify;"><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">These can seem like small details, but a clutch bearing failure can put a truck on the side of the road, restrict shifting, and possibly damage the intermediate shaft or, potentially, the entire clutch pack assembly. And that¡¯s not a come-back service call that you want to field.</span></p><p><br/></p>
