Crossflon® Subsea Bearings
Advanced Subsea Bearings Designed for Offshore Excellence
Made in Britain
Engineered for Depth. Pioneering Technology. Exclusive to Beldam Crossley.
When performance under pressure is non-negotiable, engineers turn to CROSSFLON® SUBSEA BEARINGS – high-performance subsea bearing solutions designed to meet the extreme demands of subsea applications. Manufactured in the UK by Beldam Crossley, these advanced polymer-based bearings are transforming expectations in subsea engineering.
With almost 150 years of engineering innovation, Beldam Crossley has developed CROSSFLON® SUBSEA BEARINGS to meet the critical needs of offshore infrastructure.
A Breakthrough in Subsea Bearing Performance
CROSSFLON® SUBSEA BEARINGS incorporating CROSSFLON® XS represent a new generation of engineered polymer bearings. Unlike conventional PTFE based bearings, they deliver minimal coefficient of friction values along with exceptional load-bearing capacity – vital for the challenges of subsea engineering.
Key Features of CROSSFLON® SUBSEA BEARINGS
Incorporate a proprietary filled PTFE, which delivers:
- Superior Load-Bearing Capacity: Withstand up to 75MPa in a recessed design
- Ultra-Low Coefficient of Friction: Static values a low as 0.03 under submerged conditions
- Exceptional Creep Resistance: Maintains dimensional integrity under high static and dynamic loads over lengthy periods
- Excellent Weatherability: Capable of operating across a wide temperature range, UV resistant, with near-zero water absorption.
These advantages make it the ideal subsea bearing for long-term, maintenance-free performance in the most demanding offshore conditions.
Sub Sea Applications
CROSSFLON® SLIDE BEARINGS are already in use on offshore installations including:
- SURF-Related Project: Providing engineering movement at water depths of up to 780 metres
- Modular Offshore Fabrications: Smooth installation thanks to ultra-low coefficient of friction and superior load-bearing capacity
- Offshore Electrical Platforms: Non-conductive properties making them ideally suited for use on a HVDC platform
