The runners have become pretty worn over the years and sliding the shelf

But in this application the forces are bit different to most drawer runner
uses:
- most force is applied to the sliding shelf part when it is extended
- there is a larger degree of lateral 'tilt' force on the shelf than on most drawer situations
Any thoughts about the best kind of runners to fit as a replacement here?
You can get industrial slides - Accuride is a popular make:

There's all kinds of variations - removable/non removable, different depths
of pull-out, self-closing, locking in the out position, etc.
They aren't necessarily cheap but they're designed for things like having a
50kg server hang 1m out of a rack while someone tinkers with it, and then
push it back in. They definitely don't sag when that happens.
The standard kitchen roller bearing runners from such as Blum and
Hettich can now be found with 30kg and 50kg ratings, they're not all
that expensive either, typically £5 to £10 per pair.
