The Frictionless Oscillating Bearing (FOB) is a next-generation mechanical support system engineered to replace conventional pivot and wear joints on oilfield pump jacks. Designed specifically for the repetitive vertical motion of the polish rod, this system eliminates mechanical friction through a magnetically levitated spherical bearing. The FOB integrates electromagnetic field suspension, precision alignment sensors, and self-tuning feedback control to allow for smooth oscillation with zero metal-on-metal contact.

This innovation drastically reduces wear, energy loss, and required maintenance in rod-pump systems, making it ideal for both aging wells and modern smart rigs.

Key Features:

• Zero-contact magnetic suspension eliminates friction and lubrication needs
• High-efficiency oscillation perfectly synced to rod stroke
• Sealed bearing system prevents ingress of dust, fluid, or corrosive agents
• Sensor feedback loop self-adjusts magnetic field for smooth operation
• Shock-absorbing mounts reduce vibration transfer to surface equipment
• Thermal dissipation layer ensures performance in harsh field conditions

Primary Use:

• Installed as a pivot bearing or linkage component on the walking beam or horsehead of a pump jack
• Supports the reciprocating motion of the polish rod with near-zero mechanical resistance

Additional Use Cases:

• High-load oscillating pivots in other oilfield lift mechanisms (e.g. hydraulic rod pumps)
• Retrofit kits for older pump jacks to extend their service life
• Smart well integration, allowing real-time vibration/efficiency feedback
• Non-oilfield uses: industrial linear actuators, oscillating platforms in manufacturing, wind-powered reciprocating systems, and future renewable pump systems (e.g. geothermal or hydrothermal pumps)
