Build – Measure – Learn

We are unlike our competitors because we leverage the power of the Build – Measure – Learn feedback loop to deliver new dual-use wheel-end technology at a fraction of the cost while operating with flexibility as a lean start up across multiple industries. The strengths of the company are its people, practices, and unwavering customer service.

1. People

Our team consists of high achievers with unquestionable integrity.  The value-add is immediately evident when interacting with clients and manifests itself through the feedback we receive from our customers and partners.

2. Practices

We fit our solutions to the customer, not the other way around.  We tailor to each individual customer based on their requirements and organization structure and processes through routine Voice of Customer (VOC) visits and meetings, confirming to ISO 9000 and 21500 standards in quality and project management.

3. Customer Service

We are with our customers every step of the way.  Whether we visit local maintenance shops, regional fleet owners, or conduct MVP review days showcasing and assessing products in development – our hands-on approach ensures that an engagement will not end until our customers and partners are completely satisfied with the deliverables.

Sphere Brakes perform. I'm very excited about Sphere brakes for a few reasons. It performs as-good and better than a disc brake with less up-front and maintenance costs. It's much safer for our technicians to replace the brake pad because you do not have to remove the wheel. For these reasons, we're excited to integrate Sphere Brakes into our fleet. - Harold H. Bender - President, Team Hardinger


Disc and drum brakes were invented at the turn of the 20th century, back when electricity was in it’s infancy; approximately 120 years ago. In 2010, AJ invented the first sphere brake while serving in Kuwait, heading into Iraq. The sphere brake unlocks new value to any industry leveraging more surface area in a smaller diameter. These systems directly compete in size, weight and performance. We are focused on optimizing this sphere brake technology by aligning with strategic partners in multiple industries.
Air and AOH Sphere Brakes

In service brake applications, the patented sphere brake technology leverages new v-channel shaft actuation in compression.  When the brake is applied, segmented hemispherical pads enclose on an outer segmented sphere surface.  This inherent design allows multi-directional brake force application around the brake surface generating more torque with a smaller brake effective diameter.

Sphere Driveline Brakes

In driveline applications, the sphere brake mounts in line with the drive shaft between the transmission and drive axles; It’s actuated by an electrical, mechanical, pneumatic, or hydraulic system controlled by the driver.  Like the service brake, hemispherical pads compress around the sphere brake surface typically in an enclosed housing.
