Custom uniball joints engineered for shock absorber mounting points — controlled clearance, high articulation and stable batch consistency.
If your spherical bearings cannot maintain precision under load, your entire suspension system performance suffers. We focus on structural strength, clearance control and long-term stability — not just price.
Loose clearance tolerance leads to rapid wear and sloppy handling feel — a common complaint from performance suspension customers that damages your brand.
Improper clearance specification or inconsistent liner bonding causes knocking and vibration that creates warranty claims and customer dissatisfaction.
Poor liner bonding process leads to delamination under dynamic load — especially in motorsport and off-road applications with high articulation frequency.
Outer diameter variation from batch to batch creates press-fit issues during assembly, causing production line downtime and costly rework.
Standard bearings lack sufficient misalignment angle for long-travel suspension, resulting in binding at full droop or compression and premature failure.
Low-cost suppliers deliver inconsistent clearance and surface finish between batches — creating unpredictable field performance and quality control problems.
A suspension spherical bearing — also known as a uniball joint — is installed at the shock absorber mounting point (eyelet) to replace rubber bushings and provide precise articulation under dynamic load.
Compared to rubber bushings, spherical bearings deliver measurably superior performance in handling precision, load capacity and service life consistency.
| Performance Factor | Rubber Bushing | Spherical Bearing |
|---|---|---|
| Handling Feedback | Damped | Direct |
| Load Capacity | Limited | High |
| Deflection | Significant | Minimal |
| Temperature Range | Narrow | Wide |
| Articulation Angle | Variable | Controlled |
| Service Life | Degrades | Predictable |
| Batch Consistency | Variable | Precise |
Typical Applications
We manufacture bearings compatible with industry-standard series and support custom structural modifications beyond standard specifications.
Maintenance-free design with precision-bonded PTFE liner. Low friction operation ideal for high-cycle performance and racing suspension systems where re-lubrication is impractical.
Engineered for extended articulation angles beyond standard specifications. Designed for demanding long-travel suspension applications where binding under full droop is unacceptable.
Flexible spherical bearing design with optional PTFE liner or traditional steel-on-steel configuration. Cost-effective solution with strong outer ring structure, suitable for both performance and volume applications.
Clearance directly affects handling precision, noise behavior and service life. We offer three precision clearance grades with custom specification available on request.
Minimum internal play for maximum steering precision. Designed for competitive motorsport where any deflection reduces driver feedback. Suitable for high-speed, high-load applications.
Balanced clearance optimized for street performance and aftermarket coilover systems. Excellent feedback while maintaining smooth articulation and noise-free operation.
Larger clearance designed for heavy-duty off-road applications and high-load industrial use. Accommodates thermal expansion and contamination without binding.
Custom clearance specification available upon request. We support fit tolerance recommendations based on housing dimensions and application requirements.
Every component is selected for structural performance. Heat treatment and surface finishing are controlled in-house at every stage of production.
35CrMo / 40Cr Alloy Steel. Heat-treated alloy steel outer ring provides structural backbone for radial and axial load transfer. Precision ground for dimensional accuracy and consistent press-fit performance.
GCr15 Bearing Steel / Hard Chrome Option. High-strength chrome bearing steel hardened for wear resistance under repeated oscillation. Hard chrome ball option available for extreme load and corrosive environments.
PTFE Bonded / Copper / Steel-on-Steel. Three liner configurations to match application requirements — PTFE for maintenance-free operation, copper for lubricated high-load, steel-on-steel for maximum load capacity.
In-House Controlled Process. Coordinated heat treatment ensures consistent surface hardness and core toughness. Every batch verified against hardness specification before proceeding to grinding operations.
Phosphate / Zinc / Black Oxide / Custom. Multiple corrosion-resistant surface treatment options available based on application environment, customer specification or export packaging requirements.
Marine & Extreme Corrosion Environments. Full stainless steel construction available for marine, chemical, or extreme outdoor applications where standard alloy steel surface treatment is insufficient.
We control every critical step of production. Consistency is our priority — and we back that with in-house inspection at every stage.
Precision turning and grinding of outer ring and inner ball to tight dimensional tolerance.
Controlled hardening and tempering for consistent mechanical properties across batches.
Precision bonding process with adhesion testing to prevent liner delamination in service.
Controlled grinding of inner race to achieve specified F1/F2/F3 clearance grades.
Statistical process control to maintain dimensional stability across production runs.
100% bore diameter inspection for consistent press-fit and housing compatibility.
Rockwell hardness verification on outer ring and ball after heat treatment process.
Radial clearance measured against F1/F2/F3 specification before final inspection.

Technical questions & common enquiries.
COM-T uses a bonded PTFE liner and is completely maintenance-free — ideal for performance and motorsport suspension where re-lubrication is impractical. GE series is steel-on-steel with grease lubrication, providing higher static load capacity at lower cost. GE is preferred for heavy-duty applications with accessible lubrication points.
Yes. We support full drawing-based custom production. Submit your technical drawing with bore diameter, outer diameter, width, clearance specification and material requirements. Our engineering team responds within 24 hours. Small-batch prototypes are available before volume commitment.
Yes. We assist customers with housing tolerance recommendations, outer diameter adjustment for press-fit specification, and clearance grade selection based on assembly requirements. This engineering support is included as standard OEM cooperation — not an additional service charge.
Yes. We support OEM production with customer-specified part numbers, drawings and packaging requirements. Private label packaging with custom branding is also available. We operate as a long-term manufacturing partner — not a spot supplier — designed to support ongoing product line development.
A high misalignment design features modified inner race geometry that allows greater angular deflection than standard COM-T or GE series. This is critical for long-travel off-road suspension where standard bearings would bind or generate internal stress at full droop or compression. Often used in combination with misalignment spacers.
We offer F1 (tight — racing/low play), F2 (standard — performance suspension) and F3 (looser — heavy-duty/high load). Choice depends on application load, housing tolerance, operating temperature range and noise requirements. We recommend sharing your housing bore specification so our team can recommend the appropriate grade.
Standard outer ring is 35CrMo or 40Cr alloy steel, heat-treated and precision ground. Inner ball is GCr15 bearing steel, with a hard chrome option for higher load and corrosion resistance. Stainless steel construction is available for marine or chemical environments. Surface treatments include phosphate, zinc plating and black oxide.
