Description

Revolving Truck External Halyard 1-1/4″ NPT Spindle

Revolving truck assemblies generally consist of a truck body rotating on some form of a bearing configuration and a spindle assembly which is usually threaded to fit the top of the flagpole shaft. While there is no formal industry standard for thread size, the most commonly used format is National Pipe Thread or NPT. The most common size is 1 1/4″NPT while 1″NPT and 1 1/2″NPT can also be found. Threads that are cut in an NPT format are measured and expressed differently than National Coarse (NC) or National Fine (NF) threads. When determining the proper thread for a spindle assembly, the following approximate dimensions for measuring across the bottom of the spindle should help determine the NPT size to be ordered. As a reminder, pipe threads are tapered but this should be close enough for size determination. Unless otherwise stated, all Revolving Truck Assemblies offered in this catalog have 1 1/4″NPT spindles.
