Linear bearings are divided into two series, the LM and LME series. Its code name LM series is used in Asia; Southeast Asian countries; Japan; South Korea; China, etc.. It is based on the metric scale; the linear axis outer diameter is usually used in the h7.LME series is mostly used in Europe; the United States; Germany; Italy and other regions. The British standard is the norm; there is also the metric scale; the linear axis outer diameter is usually g6. The two series of layout features; the scale is not the same; the aperture is not the same; the layout is roughly the same.
Example 1: LM 203242 UU OP
LM indicates the first series of specifications on the line
203242 indicates the scale layout aperture outer diameter length
UU indicates double seal layout OP indicates open type example 2: LME 203245 UU AJ
LME indicates the second series of specifications
203245 indicates the scale layout aperture outer diameter length
UU indicates that the double seal layout AJ indicates that the gap is adjustable by shape:
1: Straight type (shape is like a cylinder; usually a circlip device; used for small scales)
2: Flange type (with flange at the end or center; screw device; flange is usually round; square and trim)
3: Open type (shape is straight; surface has axial slit; used for occasional adjustment of space; divided into two types: large opening and small opening)
By function:
1: normal type (usually the use of functional requirements)
2: Super type (for long life and large load function requirements)
