Elastomer Hardness

60 ± 5 Shore A (IRHD)

Friction Coefficient (µ)

≤ 0.03 (Dimpled PTFE with silicone grease at max load)

Steel Grade

S355J2+N / ASTM A572 Grade 50

Anchor Stud Tensile Strength

Grade 8.8 high-tensile steel

Corrosion Protection

ISO 12944 C5-M (Very High Marine) standard coating

Operating Temperature Range

-40°C to +60°C

Shear Modulus (G)

0.9 MPa to 1.15 MPa

Testing Protocols

Prototype and production batch testing (Compression, Shear, Rotation)

Service Life Estimation

50+ Years under standard structural maintenance schedules

Technical Advantages

By utilizing advanced CNC machining and strict adherence to international metallurgical standards, our bearings deliver a near-zero friction coefficient that drastically reduces internal stress on concrete piers. Additionally, our rigorous multi-axis load testing ensures zero delamination risks and an extended service life, reducing overall total cost of ownership (TCO).

Industry Applications

High-Speed Rail Viaducts

Engineered to handle severe, repetitive dynamic braking forces and rapid vibration dissipation required for continuous concrete rail decks.

Highway Flyovers & Interchanges

Accommodates complex multi-directional thermal expansion and multi-axis rotations in curved, skewed, or post-tensioned box girder systems.

Long-Span Suspension Bridges

Heavy-duty spherical bearings designed for massive vertical load distribution and significant longitudinal displacement at expansion joints.

Seismic-Zone Infrastructure

Elastomeric and lead-rubber bearing variations configured to absorb lateral seismic kinetic energy and protect the main support piers.

Metro Rail Corridors

Compact, high-capacity pot bearings optimized for urban elevated tracks where space constraints demand minimal structural footprints.

Industrial Heavy-Haul Bridges

Reinforced structural supports built to withstand extreme axle loads from heavy freight corridors, mining transport routes, and marine ports.

Having Doubts? Our FAQ

Which design codes do Frigate bridge bearings comply with?

Our engineering and manufacturing teams strictly adhere to global standards, including EN 1337, AASHTO LRFD, and IRC:83. We provide full documentation, material mill certificates, and compliance layouts during the technical submittal phase.

Can Frigate customize bearings for existing retrofitting projects?

Yes. We specialize in engineering drop-in replacements for brownfield infrastructure rehabilitation. Our team works from your existing structural drawings to match original footprint, height, and load parameters exactly.

What corrosion protection systems are applied to the steel components?

All exposed structural steel elements undergo grit blasting to Sa 2 1/2 and are coated with a high-durability system matching ISO 12944 C5-M industrial guidelines, typically utilizing zinc-rich epoxy primers and polyurethane topcoats for aggressive marine environments.

How are the bearings tested before dispatch?

Every batch undergoes strict factory production control testing. This includes visual inspections, dimensional validation, and physical load testing (vertical compression and shear stiffness evaluation) on our calibrated in-house hydraulic presses.

What are the typical maintenance requirements for these units?

Frigate bearings are designed to be virtually maintenance-free. However, we recommend routine visual inspections every 12 to 24 months to check for debris accumulation, clear drainage, unusual elastomeric bulging, or unexpected structural shifting.
