Industrial Weld on Ball Joints Frequently Asked Questions
What are industrial weld on ball joints used for?
They are used in fabricated linkages, control arms, steering systems, cylinder connections, clevis assemblies, rod ends, and custom heavy-duty motion systems.
What is the difference between shouldered and not-shouldered versions?
Shouldered versions include a shoulder geometry for specific weld-in or locating requirements, while not-shouldered versions provide a simpler retainer profile.
Which dimensions should I compare first?
Start with pin size, retainer OD B, ball width C, retainer width D, and then confirm angle A and angle B.
Why are strength values included in the chart?
Ultimate retainer strength and ball push-out force help buyers compare joint capacity references before requesting application-specific confirmation.
What material structure is listed for this catalog family?
The catalog lists a 45# carbon steel zinc-plated housing, a 52100 bearing steel or 45# carbon ball with hard plating and heat treatment, and a metal-to-metal structure.
Can SYZ support custom weld-on ball joint requirements?
Yes. Send drawings, target pin size, retainer geometry, load expectations, grease fitting or groove needs, finish requirements, and annual volume for review.
