CN Crosshead Jamnut
Operating Temp: -50ºF to 500ºF
Description: CN Crosshead Jamnuts are safe and easy to install/remove on compressor crossheads. They were designed in conjunction with a major compressor manufacturer. Crosshead Jamnuts have Superbolt® patented "captive" machinery type jackbolts as an added safety feature. The bolt circle is larger than on standard torquenuts™ to allow wrench clearance from the piston rod.
Application Examples: Compressor crosshead.
SP Piston End Nuts
Description: These nuts are “Torquenut™” type Multi-Jackbolt tensioners designed to properly attach compressor pistons to the piston rod. There is no need to clamp the piston rod when installing or removing SP Nuts. Because almost every compressor piston is custom designed to accommodate different gases at different temperatures, the Piston End Nuts that attach the pistons to the rods also vary. The space available for Piston End Nuts varies. Nut material may also vary due to corrosion resistance requirements. Superbolt® has an extensive data base of previously designed and installed Piston End Nuts. New applications can usually be designed by modifying an existing design. Most Piston End Nuts have Superbolt® patented “captive” machinery type jackbolts as an added safety feature.
Application Examples: Piston end nut, hydraulic pistons
