LME12 Standard European‑size Linear Ball Bearing 12×22×32mm Open‑type CNC Automation 3D Printer Guide Spare Part
LME12 is an open‑type metric European‑series cylindrical linear ball bearing, designed for smooth low‑friction linear movement along 12‑mm guide shafts. Circulating steel balls convert sliding friction to rolling friction to deliver accurate reciprocating motion. Its standard compact dimension is widely interchangeable for automation equipment, CNC machines and 3D‑printing devices.

Q1: What is LME12 bearing?
A1: It is an open‑type European‑series cylindrical linear ball bearing for 12‑mm diameter guide shaft.
Q2: What is the difference between LME12 and LME12UU?
A2: LME12 is open‑type without seals, LME12‑UU has double‑side rubber seals for dust‑proof protection.
Q3: Can this bearing carry heavy radial loads?
A3: It is designed for light‑to‑medium radial loads and pure linear motion, not suitable for heavy‑load working conditions.
Q4: What is the difference between LM12 and LME12?
A4: LM12 is Japanese standard size, LME12 is European standard with larger outer diameter.
