PTFE, Industrial Sealing, Bearing & Polymer Solutions Global Leaders
We have been innovators in our industry for over a century. Since 1876 we have a solid track record of providing industrial sealing technology that protects lives, investments and environments. We have always been, and always will be, committed to research and development to move our technologies forward. This commitment to continued innovation enables us to meet the needs of our customers now and in the future.
All Beldam Crossley products are manufactured to an incredibly high standard. To do this, we manufacture from two locations based in the northern part of the UK. We operate to international global standards including BS EN ISO 9001 and BS EN ISO AS 9100. We work within industries where quality is paramount, and we take this responsibility very seriously. Many of the products we provide are used to protect lives – failure is not an option.
Today we are recognised as being at the leading edge of industrial technology. We have gained this reputation through our continued dedication to development and our ongoing investment in our manufacturing facilities.

Aerospace
Over the last 60 years Beldam Crossley has built a sound reputation for quality and service within the aerospace industry. Find out more here.
Automotive
When Beldam Crossley first invented sealing technology almost a hundred and fifty years ago, it was for the marine industry. Find out more here.
Construction
In the early 1960s Beldam Crossley became one of the first UK firms to process PTFE Polymers. In the half century since then, we have established ourselves as a leading supplier of PTFE products. Construction companies worldwide rely heavily on our expertise in this field. We have developed our Crossflon® range of proprietary polymers to be effective in even the most challenging of environments.
Renewables
Wind power is the furthest developed renewable energy source. With the world needing more and more energy, but a better environment, wind turbines are one of several options being invested in for the present and future energy creation.
Marine
The origins of Beldam Crossley can be traced to 1876, when ship engineer Asplan Beldam discovered a solution for what had previously been an impossible problem. With this solution, Beldam was able to design specific products tailored to improving efficiency in steam driven vessels.
Oil & Gas
Our proprietary Crossflon® blended grades of PTFE are used in both onshore and offshore applications. These range from down-hole drilling, valves, pumps, compressors and generators.
Petrochemical
In the past half century we have established ourselves as a leading supplier of products based upon the PTFE polymer material. These products are supplied to major Petrochemical companies worldwide.
Power Generation
When it comes to Power Generation, Beldam Crossley is focused on the current and future requirements of the industry globally.
We work to develop opportunities for equipment design and plant engineers through wide ranging and innovative products, designed specifically for use within the sector. Find out more here.
