Rod-End Rebuild and Replacement
Precision steel balls can replace worn spherical elements in serviceable rod-end or flex-joint assemblies when the ball geometry and fit are matched to the housing and race.

Overview
STEEL BALL CBL-DP Product Overview
CBL7DP is a replacement rod end steel ball with 0.4375″ bore (B), 0.812″ ball diameter (D), and 0.562″ width (W).
Made from 52100 bearing steel — precision ground, heat treated, and hard chrome plated. The CBL-DP series balls are dimensioned to drop-in replace worn balls in standard rod end bodies. Used when rebuilding rod ends rather than replacing the complete assembly. 440C stainless steel balls available for corrosive-environment rod ends. Suitable for all standard series rod end bodies in the matching bore size.
440C stainless steel option available. High-misalignment ball equivalent: HMBL series. Sold individually; inspect housing bore and race for wear before installation.

FAQ
STEEL BALL CBL-DP Frequently Asked Questions
What is the CBL7DP steel ball used for?
The CBL7DP is a replacement rod end steel ball dimensioned to drop into standard rod end bodies in the matching bore size. It's used when rebuilding a worn rod end rather than replacing the complete assembly.
What are the bore, ball diameter, and width of the CBL7DP?
Bore (B) is 0.4375", ball diameter (D) is 0.812", and width (W) is 0.562" — match these to the housing bore and race you're rebuilding before ordering.
What material is the CBL7DP made from?
Standard material is 52100 bearing steel, precision ground, heat treated, and hard chrome plated. A 440C stainless steel version is available for corrosive-environment rod ends.
Is a stainless steel version of the CBL7DP available?
Yes. The 440C stainless steel option is available for rod ends operating in corrosive environments where the standard 52100 hard chrome ball isn't sufficient — specify 440C when requesting a quote.
What's the difference between the CBL7DP and the HMBL series ball?
The CBL7DP is the standard-misalignment CBL-DP replacement ball for this bore size; the HMBL series is its high-misalignment equivalent, for rod end bodies that need a greater articulation angle than the standard ball geometry allows.
What should I check before installing the CBL7DP?
Inspect the housing bore and race for wear before installation — the CBL7DP is sold individually and is meant to drop-in replace a worn ball in an otherwise sound rod end body, not to compensate for a worn or oversized race.
