I'm in process to build my second CNC using 80/20 and THK linear rails and actuator (for z). I bought 4 rails online two with two trucks per rail and two with one. None of them have greasing nipple but the grease is pretty dirty so I cleaned one, but now I'm tryng to figure out where can I get grease fitting for this. there is no model number it only shows THK TBA 20 JAPAN and on the wipers it shows NSR 20 but I can't find any info for them on THK website.
Here are some pics. I think its 0.75mm pitch but nut sure. Also is it ok to use white lithium grease on these rails ?
