I’ve had a similar issue with my trailer, and I found that using a silicone-based lubricant works really well for this kind of thing. It won’t harm the rubber rollers, and it can be sprayed directly onto the shafts without needing to disassemble everything. I’ve used it in the past for boat trailers, and it lasts a good while, even in tough weather. Another option to consider is HNBR (hydrogenated nitrile rubber) for any replacement parts or rollers if they ever need swapping out. It’s super durable, resistant to wear, and won’t eat away at the rubber.
