I recommend this product
The old insert had been dostorted by not using the proper tool, so was difficult to remove. New one fitted perfectly when fully greased, and I intend to look after this one.

I Have A Couple Of The Halfords Original Folding Bikes.

They have a BB i.d. of 51.3mm (unthreaded) and a shell width of 69mm. Will the Thorn insert fit satisfactorily? They appear to take JIS axles/cartridge bearings. How much eccentricity is available please?
SJS Customer Service:
Hi,

Unfortunately this eccentric shell is too short to be used within your frame and none of our other eccentric shells match your dimensions either I'm afraid.

Thanks.
How Long Does The Bottom Bracket Have To Be?

I have a thorn catalyst, and the bb now has play. I can see it has to be 73mm, but what length do I need please?
SJS Customer Service:
Hi,

I cannot know the length for sure because it is the overall length is relevant to the cranks not the actual frame. The cranks that would have come as stock on your bike have long been discontinued but as far as I'm aware they were designed around a 110mm bb but I can't say for definite.

Thanks.
