Why Lubron TF?

Engineered. Durable. Reliable.

Lubron TF bearings provide a premium solution for applications requiring low-friction movement under heavy loads. The woven PTFE fabric liner technology offers superior resistance to wear, cold flow, and compressive creep while accommodating expansion, contraction, vibration, rotation, and structural displacement.

Designed for long-term performance in extreme environments, Lubron TF bearings have delivered reliable service in critical infrastructure projects for decades.

  • Supports demanding structural and heavy-duty applications with load capacities significantly exceeding conventional PTFE bearing systems.

  • Woven PTFE fiber technology delivers very low coefficients of friction while minimizing stick-slip movement.

  • Proprietary PTFE fabric construction minimizes wear and extends service life under repetitive movement and heavy loading.

  • Maintenance-free sliding surfaces eliminate the need for external lubrication.

  • Designed to handle thermal movement, structural rotation, angular misalignment, and seismic displacement.

  • Reliable performance from -148°F (-100°C) to 500°F (260°C) with intermittent exposure up to 550°F (288°C).
