POT Bearings

POT bearing consisting of a metal piston supported by a disc of unreinforced elastomer that is confined within a metal cylinder for allowing rotational movement about any axis in horizontal plane and to bear and transmit vertical load. Pot bearings may be provided with sliding assembly (with or without restraint in the form of guide along a desired direction to bear and transmit horizontal force) comprising of stainless steel plate attached to metal backing plate sliding in horizontal plane over sliding material confined in recess(s) on the piston which shall be termed as Sliding / Guided Pot bearings.

Key Advantages

1. Outstanding Load-Bearing Capacity

Ameenji’s POT-PTFE bearings are specifically engineered to support extremely high loads while evenly distributing weight across the structure. This high load-bearing capability is essential for large-span bridges and heavily trafficked roads, ensuring structural stability and enhancing lifespan.

2. Accommodates Multi-Directional Movement and Rotation

Designed to handle both rotational and translational movement, our POT-PTFE bearings accommodate structural shifts due to temperature changes, load variations, and seismic activity. This flexibility reduces stress on the structure and helps prevent cracking, damage, and uneven settling.

3. Low Friction and Smooth Operation

The PTFE (Polytetrafluoroethylene) sliding material in our bearings ensures a low-friction interface, allowing smooth, unrestricted movement. This reduces wear, minimizes maintenance, and provides a quieter and more comfortable experience for vehicles on elevated roads and bridges.

4. Durability in Extreme Conditions

Our POT-PTFE bearings are crafted from premium materials, including high-grade steel and PTFE, making them resistant to corrosion, extreme weather, and UV exposure. This robust construction ensures reliable performance and longevity, even in demanding environmental conditions.

5. Minimal Maintenance Requirements

Ameenji’s POT-PTFE bearings are designed to require minimal maintenance, thanks to the self-lubricating properties of PTFE and the durable construction materials. Routine inspections are generally sufficient, lowering maintenance costs and minimizing disruptions in critical infrastructure.

6. High Safety and Structural Stability

With their ability to evenly distribute stress and accommodate movement, our POT-PTFE bearings provide enhanced safety and stability for structures. This stability is essential for bridges and overpasses, minimizing the risk of structural damage and ensuring user safety.

7. Customizable Solutions to Fit Specific Needs

Ameenji Rubber Limited offers customizable POT-PTFE bearings to meet each project’s unique requirements. Our team works with clients to design bearings that align with load, movement, and environmental demands, ensuring the perfect fit for optimal performance and reliability.

Types of POT Bearings

Components of POT Bearings

  • Pot: The main body of the bearing, usually made from steel, which contains the elastomeric disc and provides structural support.

  • Elastomeric Disc: A confined elastomeric pad placed inside the pot, allowing for rotations by deforming under load while remaining contained within the pot.

  • PTFE Disc: A layer of PTFE material that sits atop the elastomeric disc, providing a low-friction surface for sliding movements.

  • Stainless Steel Plate : A polished stainless steel plate that slides over the PTFE disc, ensuring smooth translational movement with minimal friction.

  • Guide Bars: In guided pot PTFE bearings, guide bars are used to restrict movements to a specific direction, ensuring controlled translations and preventing unwanted lateral movements.

Maintenance of POT-PTFE Bearings

Regular maintenance of POT-PTFE bearings is essential to ensure their longevity and optimal functionality. Inspections should focus on the PTFE sliding surfaces for signs of wear, as well as any debris buildup that could impact movement. It’s also important to check the integrity of the steel components, particularly for signs of corrosion or damage due to environmental exposure. Lubricating moving parts and ensuring that bolts and fasteners are secure helps maintain alignment and stability. Routine cleaning and inspections will help detect early signs of wear, minimizing potential damage and maintaining the structure’s safety and performance over time.
