Uniball Suspension Mounts
Uniball cups retain a spherical bearing in a fabricated suspension or control-arm structure while allowing the bearing to articulate. Check cup fit, retaining method, bracket stiffness, and misalignment clearance.
UNIBALL CUPS
• Housing: 4130 chromoly steel (Mild steel optional).
• Snap Ring: Retainer included.
• Precision: Machined from 4130 chromoly steel.

What Is UNIBALL CUPS?
UNIBALL CUPS are cup-style housings that retain a spherical bearing in a fabricated control arm, suspension upright, steering member, or custom chassis structure. The cup transfers the bearing load into the surrounding bracket while allowing the inner spherical element to articulate. Match the cup and bearing dimensions, retaining method, weld sequence, bracket stiffness, and misalignment clearance as one engineered assembly.
Typical Applications
Applications for UNIBALL CUPS
Motorsport and Off-Road Chassis
Cups are widely used in custom vehicle fabrication for upper and lower control arms, steering knuckles, and other spherical-bearing mounts. Match the cup and bearing sizes as one assembly.
Serviceable Fabricated Bearing Points
A cup-based mounting arrangement can simplify bearing replacement and inspection in custom structures. Confirm weld sequence, alignment, edge support, and corrosion protection before final assembly.
Performance Steering Geometry
Useful in steering and geometry correction assemblies that require rigid spherical bearing support points.
Motorsport and Off-Road Fabrication
A fit for motorsport and off-road builds needing durable weld-in cups matched to common spherical bearing sizes.
OEM Fabricated Assemblies
Useful in repeat production where standard and special cup widths are specified for fabricated suspension systems.
Product FAQ
Frequently Asked Questions
What is a uniball cup used for?
A uniball cup is a weld-in housing used to retain a spherical bearing with a snap ring retainer.
What material is standard for the UBC series?
Standard construction uses 4130 chromoly steel, with mild steel available as an option.
Why are B and D the first fitment checks?
They determine the bearing seat and housing size needed for the spherical bearing package.
What does the snap ring do?
The snap ring retains the spherical bearing in the cup and allows serviceable replacement.
Are special sizes available?
Yes. Special sizes are available in volume for custom fabrication and OEM production.
How do I choose the correct uniball cup?
Start with B and D, then confirm W, fit bearing family, and snap ring part number for the intended assembly.
