XM XF Frequently Asked Questions
What is the difference between XM and XF rod ends in this series?
XM parts are male rod ends with an external shank thread, while XF parts are female rod ends with an internally threaded body. Both belong to the same heavy-duty chromoly series and share the same self-lubricating race construction.
What body and race materials are used in the XM-XF series?
The XM-XF series uses a 4130 chromoly steel body with heat treatment and hard chrome plating, a 52100 bearing steel ball, and an injection-molded reinforced nylon race with PTFE for self-lubricating articulation.
Are both right-hand and left-hand thread versions available?
Yes. Right-hand and left-hand configurations are both available across the series. Male parts use XMR or XML prefixes, while female parts use XFR or XFL prefixes depending on thread direction.
What kind of applications is the XM-XF series designed for?
This series is suited for off-road suspension systems, competition vehicles, agricultural machinery, industrial linkages, and other heavy-duty motion-control assemblies that require high strength and reliable articulation.
Do XM-XF rod ends require regular greasing?
No. The PTFE-reinforced nylon race is self-lubricating, so the series is intended to operate without routine external greasing under normal application conditions.
Are studded, metric, or stainless versions available for XM-XF products?
Yes. Studded configurations are available by adding an S suffix to the part number. Metric equivalents are available in the MXM/MXF series, and stainless steel material options are also available on request.
