Machining threads on heavy equipment shafts or spindles can be difficult and time consuming, requiring larger diameter stock and leading to costly product scrap if the threads are under-turned.
Instead, by using a unique two-piece threaded insert called Thredserts, from Meibuhr, external threads can be added quickly and easily anywhere on the shaft or spindle without machining threads. Thredserts assemble into a simple groove in the shaft or spindle without special tools. Standard bearing locknuts and lockwashers contain and lock the assembly.
With the use of a Thredsert, maintenance managers can reduce maintenance cost and downtime since entire equipment assemblies, including the shafts or spindles, do not have to removed and replaced to repair a damaged thread. If a thread is damaged, it can be quickly and independently replaced.
Heavy equipment designers can expand product design possibilities while shrinking their design envelope size using Thredserts, which allow putting external threads anywhere on the shaft regardless of its design. For instance, multiple thread sizes can be accommodated on the same shaft without having to step down the shaft diameter.
Thredserts are available in a variety of standard thread sizes for shaft diameters of 1” to well over 6”. They are typically made of steel or stainless, and custom sizes and materials are available including exotics.
