TR and TR-N precision series female rod ends are a popular choice for general industrial applicati***, including control linkages
in packaging, printing, material handling, actuators and bag closures, etc.
NOTES
* 1. Rod ends with Zerk type grease fittings can be obtained by ordering the TR-N series; Example: TR-8N.
2. Grease fittings are ***ailable on sizes 4 through 16 only.
3. Optional flush type fittings are ***ailable on special order by adding “FN” suffix to the part numbers; Example: TR-8FN.
