STEEL BALL CBL-DP Product Overview
CBL4DP is a replacement rod end steel ball with 0.2500″ bore (B), 0.500″ ball diameter (D), and 0.375″ 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.

STEEL BALL CBL-DP Frequently Asked Questions
What is the CBL-DP steel ball series used for?
CBL-DP steel balls are used as precision spherical replacement components in rod end and related joint hardware.
What material is standard for these steel balls?
The standard material is 52100 bearing steel, with 440C stainless available for special requirements.
What treatment is applied to the steel balls?
The series is heat treated and hard chrome plated to improve wear resistance and service durability.
Why is precision grinding important for steel balls?
Precision grinding helps maintain consistent fit, smooth articulation, and repeatable rebuild quality across assemblies.
Can I request non-standard steel ball sizes?
Yes. Special sizes are available in volume for custom rebuild and production programs.
How do I choose the correct steel ball size?
Start by matching D and B dimensions to the original hardware, then confirm W and any rebuild-specific fit requirements.
