More Than a Bushing. A CAE-Driven, Precision Elastic Joint.
A rubber bushing is a critical component for controlling Vibration, Noise, and Harshness (NVH). It provides an elastic interface between two rigid parts. Its core functions are:
Vibration Absorption: Isolating high-frequency vibrations.
Allowing Motion: Permitting controlled torsional or conical movement.
Bearing Loads: Supporting dynamic and static loads without rigid impact.
The GJBUSH Manufacturing Advantage:
We use CAE (Finite Element Analysis) and our internal materials database to simulate the stiffness curve, stress distribution, and fatigue life before cutting the mold. We deliver a data-driven, predictable, and high-performance engineering solution, not just a “part.”

We Control the Entire Process: The SGS IATF 16949-Driven OEM/ODM Model
We are not a trading company; we are the manufacturer. GJBUSH's SGS IATF 16949 system governs every step, from R&D to final testing, to ensure "consistent quality."
The GJBUSH Manufacturing Loop:
- In-house R&D (Database-Driven): Accessing our materials database and using CAE to develop proprietary formulas.
- Precision Tooling: In-house mold shop for high-accuracy tooling and rapid prototyping (T0).
- Metal Prep: Automotive-standard automated adhesive application for a superior bond.
- High-Pressure Vulcanization: Strict process controls for zero-defect molding.
- 100% Performance Testing: Dynamic/static stiffness and durability testing to ensure we exceed OEM standards.
The GJBUSH Rubber Bushing Product Line: Precision-Matched to Your Application
As an IATF 16949-certified OEM/ODM factory, we manufacture the following bushing types based on your drawings and operating conditions, precisely meeting your specific performance, durability, and NVH targets.
1. Cylindrical Bushings
Core Application: The most universal design, used to manage radial loads and vibration.
Specific Scenarios: In Automotive, widely used for stabilizer bar links and shock absorber mounts. In Micro-Mobility, used for the suspension linkage points and folding stem bases of e-scooters (like Segway).
2. Flanged Bushings
Core Application: Used when a component requires axial locating or needs to withstand lateral thrust.
Specific Scenarios: In Automotive, commonly found at the connection points of control arms to the subframe. In Industrial Machinery, used as mounting feet for pumps or motors, providing both isolation and positioning.
3. Hydraulic Bushings
Core Application: An advanced NVH solution that uses internal fluid to achieve “frequency-selective” damping.
Specific Scenarios: In Automotive, primarily used in the engine and subframe mounts of luxury vehicles to precisely cancel out specific frequencies, such as engine idle vibration.
4. Custom-Molded Designs
- Core Application: Fully co-developed for your unique packaging, load, or performance targets.
- Specific Scenarios: This is the core of our OEM/ODM capability. Examples include the high-torsional-stiffness slewing drive bushings we customize for PV Trackers or the custom-shaped isolators for Home Appliance HVAC compressors.
Performance Proof: Exceeding the 5-Year / 100,000 km Durability Promise
The GJBUSH factory is certified to the SGS IATF 16949 automotive quality management standard. Our promise is based on data.
What this means for our OEM/ODM clients: Our materials database is built from our own rigorous testing. Every bushing we deliver has been validated in-house to performance standards (especially anti-aging and fatigue durability) that exceed the OEM 5-year / 100,000 km requirement. We use tougher tests to guarantee your product’s whole-life performance.
Core Testing Capabilities Include:
Dynamic & Static Stiffness Testing
Tri-axial Durability & Fatigue Testing
High/Low-Temp Aging & Salt Spray Testing (-40°C to 150°C)
Rubber-to-Metal Bond Strength Peel Testing
The Choice of Global #1: GJBUSH x Segway
When the micro-mobility leader, Segway, needed an NVH solution for their flagship e-scooters, they required a partner who could blend automotive-grade reliability with high-frequency vibration absorption.
- The Challenge: E-scooters produce vibrations at a much higher frequency than cars and demand extreme durability.
- The GJBUSH Solution: We leveraged our automotive materials database to develop a new high-dampening proprietary formula, and used CAE to optimize the bushing structure to achieve superior shock absorption without sacrificing durability.
- The Result: GJBUSH became a core supplier to Segway. Shipments in this category are projected to hit 6 million units, making us #1 globally.

GJBUSH Tech Guide: How to Select the Right Bushing Based on Data
The wrong bushing leads to premature failure. The GJBUSH process is scientific and traceable:
Analyze Loads & Conditions (CAE Simulation)
We first analyze your load types (radial, axial, torsional), stress points, and target stiffness using CAE.
Match the Materials Database (Proprietary Formulation)
Based on CAE data and operating conditions (temp, media), we select and customize a proprietary formula (NR, EPDM, NBR) from our materials database that meets your aging and stress requirements.
Optimize Geometric Design
We optimize the bushing’s shape and pre-compression to hit the target “stiffness curve,” solving NVH problems before the mold is cut and shortening your R&D cycle.
Common Questions About Custom Rubber Bushings
How did you become the #1 supplier for [e-scooter] bushings?
Through “Technology Migration.” We applied our automotive-grade material R&D (materials database, CAE) and quality control (SGS IATF 16949) to the micro-mobility sector. This provided durability and performance far above the industry average, earning the trust of leaders like Segway.
How do your bushings exceed the "5-year / 100,000 km" standard?
Our standard comes from our materials database and rigorous internal testing. We set our internal test protocols for anti-aging and fatigue durability higher than OEM requirements and use our IATF 16949 system to ensure it’s met every time.
As an OEM/ODM factory, what is your MOQ?
The MOQ depends on the bushing’s complexity and size. As a source factory, we are highly flexible for co-development projects (R&D stage). We are more focused on building long-term technical partnerships. Please speak with our engineers.
What is the lead time for new tooling and T0 samples?
Generally, our in-house tooling center can deliver T0 (first-off-tool) samples approximately 3-4 weeks after final drawing confirmation, depending on design complexity.
