Chromoly Male Rod End (Three Piece Series)

This series of rod ends consists of a body, ball and race. This type of construction allows for the use of different metals for each component part. The body is manufactured out of 4130 steel alloy, which is heat treated, and zinc plated. Specifications for the race are heat treated alloy steel, zinc plated, and chromate treated materials. The ball is made from 52100 steel (AMS-7440) and is heat treated, and hard chrome plated.


What is Radial Static Load Capacity?

These loads are based upon the minimal mechanical properties of the design configuration of the stressed areas. The Operation Load Capacity of FK Bearing rod ends is based upon the Radial Static Load Rating. Appropriate safety factors should be utilized with the application. Full rotation assemblies up to 100 rpm should not exceed 10% of the radial static load.


What is Axial Load Capacity?

Cross-section drawing of a rod end with a spherical bearing ball and race in a housing on a straight shank, with a dashed centerline arrow through the ball bore

Axial static load is the force that is applied through the bore of the ball. Maximum axial static load capacity is recommended at 15% of the radial static load for FK Bearing two piece rod ends, 10% for three piece rod ends.


What is Bearing Misalignment?

Line drawing of a clevis bracket with a bolt through it, hex head one side and hex nut the other, capturing a threaded rod end

A rod end or spherical bearings ability to mis-align is measured by the degree of angle the ball can accommodate without interference.

Questions and Answers

Why should I choose a PTFE Liner?

A PTFE (Teflon) liner greatly increases dynamic wear characteristics and is recommended for applications like 4-links, ladder bars, and suspensions.

The special mil-spec PTFE fabric liner is bonded directly to the race—providing smooth, maintenance-free operation without needing any additional lubrication.

This PTFE lined option should not be confused with other rod end manufacturers' soft Nylon races.
