Rod End 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 XM-XF series and share the same core performance direction.
What industries commonly use the XM-XF series?
The XM-XF series is commonly used in off-road racing, agricultural equipment, industrial linkages, marine hardware, and other motion-control assemblies that need compact articulation and dependable load capacity.
Are both right-hand and left-hand thread versions available?
Yes. The XM-XF series can be supplied in right-hand or left-hand thread configurations depending on the part number and linkage design requirement.
Can I request custom materials or finishes for XM-XF products?
Yes. For OEM or repeat-order programs, SYZ can discuss custom body materials, plating, special packaging, and other production requirements based on your application.
How do I choose the correct bore and thread size?
Start from the required ball bore, thread size, and body style, then match them against the XM-XF size chart. If your assembly has special dimensional constraints, send the target dimensions to us for selection support.
Do all XM-XF rod ends use the same race material?
Not always. Some variants may use a race liner while others may differ by structure, so the exact build should be confirmed from the product spec or inquiry response for the target part number.
Can I order samples before placing a bulk order?
Yes. Sample support is available for qualification. Standard policy is free samples with freight handled separately unless otherwise agreed.
What is the usual production lead time for XM-XF orders?
Typical lead time is around 7 to 15 days depending on order quantity, stock condition, finishing requirements, and whether any custom packing or OEM marking is needed.
