Sleeves too long but ok. More importantly, the mounting holes are oversized and NOT THREADED. This part will NOT work for the Ender 3 or CR-10 unless tampered with by a jury. I made the mistake of buying them and now I can sell about 60 pieces. Revain's description is wrong (AHEM, just a lie). They say it won't work directly on 3D printers. "Widely used: used for Creality Ender 3 CR-10 CR-10s 3D printers etc." is just not true.
