    I haven't fitted greasing fittings to my carriages as it's a PITA with the 15mm Hiwin's. Can I get away with just oiling the rail and then moving the carriages a few times over the oiled area.

    I bought 2nd hand Hiwin and when I first got them they were a little tight but the jig had not been moved in a long time. I added a little synthetic engine oil to the rails and ran the carriages a few times over the oil and because super silky smooth like my clone rail is (Clone rail and carriages were new). I also realised I'll have to strip it down to add greasing points so oiling the rail would save me a lot of hassle.

    If you didn't buy it from China the company you bought it from did ;)

    The idea of greasing the actual carriage, is it lubricates the passageways and provides lubrication for a good period, plus it helps to flush out contamination. By just oiling the rail, at best you'll get a coating of oil on the balls, and are more likely to get contamination into the carriage.

    Someone posted a link to these 4mm fittings a while back, and I ordered 20 of them. But I haven't checked to see how well they'll work.

    Hiwin carriages already come with a grease nipple, at least mine did, but you will struggle to find a fitting for them that does not leak grease everywhere, there seems to be a lot of back pressure from the bearing.
