22-Open Type-LM-AJ

The Open Type-LM-AJ is a specialized linear ball bearing featuring a radially open (cut) outer ring and an AJ-style design (often referring to a specific internal cage or ball groove configuration). The key characteristic is the "Open" structure, which means the bearing has a gap along its radial direction. This allows for micro-adjustment to compensate for slight misalignments or mounting errors, and it can also provide a clamping force on the shaft when properly installed in a housing that closes the gap. This design reduces the negative effects of alignment inaccuracies, minimizes bending, and ensures smooth, precise linear motion. The "AJ" suffix typically indicates enhanced performance characteristics, such as high rigidity, low noise, and long service life.
