TIMKEN SURvIvOR PT SERIES<br />
<strong>Timken</strong>’s SURVIVOR Series housed units have been created to handle stringent food<br />
handling requirements and serve in highly corrosive applications. All assembly components<br />
have been carefully selected to comply with federal food processing requirements without<br />
compromising bearing performance needs.<br />
The patented SURVIVOR PT polymer housed units have been tested to withstand a wide<br />
range of highly corrosive chemicals commonly found in food and beverage processing<br />
industries. These units are dimensionally stable under load and can operate in continuous<br />
temperatures up to 250° F (brief exposure up to 350° F) and the finish will not scrape or flake<br />
off during use.<br />
The bearing inserts, given the proprietary <strong>Timken</strong> thin dense chrome coating, are combined<br />
with stainless steel locking collars to provide superior corrosion protection. This coating is<br />
a thin, dense chrome coating that will not crack or peel under known application conditions.<br />
The bearing housings are available as high-base and low-base pillow blocks, and 2-bolt and<br />
4-bolt flanged cartridges for popular shaft sizes of 3 /4 in. through 1 1 /2 in. and 20 mm through<br />
40 mm diameters. Bearing inserts are available with the self-locking collar or the setscrew<br />
locking device. The SURVIVOR PT assemblies are dimensionally interchangeable with the<br />
current line of <strong>Timken</strong> cast iron housed units.<br />
The SURVIVOR Series provides extraordinary corrosion resistance for food and beverage<br />
industries, materials handling operations, dairy and refrigeration applications, as well as<br />
HVAC, chemical, maritime and other highly corrosive environments.<br />
All materials used in the SURVIVOR assemblies, including the grease, are approved for<br />
USDA and FDA compliant industries.<br />
ORDERING INFORMATION<br />
To order complete SURVIVOR polymer assemblies, simply add the “PT” suffix to the current<br />
cast iron housed unit designations.<br />
Example:<br />
YCJT 1 PT or RAK 3 /4 PT<br />
Refer to the corresponding cast iron housing design for dimensional data. Consult your<br />
<strong>Timken</strong> sales representative or an authorized distributor for shaft size availability.<br />
SURVIVOR inserts can be ordered using <strong>Timken</strong>’s standard part number for wide inner ring<br />
bearings with a “TDCF” suffix. Example:<br />
