LM20 is an open‑type metric standard cylindrical linear ball bearing designed for smooth low‑friction linear movement along 20mm guide shafts. Built‑in circulating ball elements convert sliding friction into rolling friction, delivering precise reciprocating motion performance. Its compact standard dimension makes it widely interchangeable for automation equipment, CNC machines and 3D‑printing devices.

Q1: What is LM20 bearing?
A1: It is a standard open‑type cylindrical linear ball bearing for 20‑mm diameter guide shaft.
Q2: What is the difference between LM20 and LM20UU?
A2: LM20 is open‑type without seals, LM20‑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: Is lubrication needed for LM20 open‑type linear bearing?
A4: Yes, regular grease lubrication is required to reduce friction and prevent premature wear.
