Maintenance Free Roller Chains Freedom Series PT-Type Self Lubricating Chains Freedom Series Self-Lubricating chains offer premium performance and value in a sintered maintenance free product. It features the addition of a roller for reduced friction smoother operation over sprockets, and specially coated pins and link plates for rust prevention and improved wear life. They are available in PT-Type, for most drive or power transmission applications, and C-Type, for conveyor applications. Nickel plate or Perfect Coat PlusTM are also available. The PT-Type chains are made with slightly modified dimensions to achieve the same strength and working load values as ASME/ ANSI standard chains (unlike standard SL-Series products which possess reduced ratings). This allows them to be direct replacements on many slow to moderate speed drives. These chains are available in single strand only and will operate on standard ASME/ANSI sprockets. Normal Operating Temperature 14 F to 158 F Also available in Nickel Plate or Perfect Coat PlusTM Freedom Series PT-Type Self-Lubricating Roller Chain Specifications Chain Dime nsions Are Give n In Inche s Rolle r Plate Rolle r Pin Pin Plate Link Plate Diame te r Diame te r Thickne ss Thickne ss He ight Tr R D Tp H Riv.
