Following one of our printers suffering a bearing failure and trashing the linear rod, we replaced them with the following:
PSFJ8-370 x2
PSFJ8-330 x2
PSFJ8-320 x2
LM8UU x10
With freight it ended up being about $200AUD for the lot.
These have close to 10K print hours on them with no issues, and they’re less noisy than the stock ones.
