    not as best shown with linear bearings

    These bearings do not have rounded protrusions on the outside, and the axial holes in the metal are square, not round. They weren't very smooth either, wouldn't recommend. Bearing 3x7x10.

    Pros
    • Due to the need for lubrication, some oil gets on the product.
    Cons
    • Doubtful purchase for the elderly

    58% or 7 out of 12 were good.

    I tested all 12 when they arrived. 7 of them worked well, slid easily over the bar. The remaining 5 moved roughly and firmly along the bar. I've tried oiling them and screwing them on by hand to no avail. From what I've read online this is the average for a LM8UU at this price point.

    Pros
    • These bearings are proven to be durable and offer precise, low-friction linear motion.
    Cons
    • Expensive

    1 missing, another damaged - but generally good

    Note to seller: Please help with the problem below. I will update the review accordingly. Firstly the price was for a pack of 4 LM3UU linear bearings and only 3 came. I ordered two packs, one was perfect all 4 were in plastic cases but the other...the other only had 3 and one of them was exterior Plastic case that was destroyed. And unfortunately, this camp also performs the worst. It's too free and has many games. Considering they cost about $3 per bearing I was hoping to at least get…

    Pros
    • Bearing of different sizes is standardized, replaceable, don't worry if the replacement is worn out
    Cons
    • Long delivery time
