Customers often gets confused why some linear guides (including miniature) in our catalog are described as “interchangeable”.
In the Misumi catalog word “interchangeable” is used to describe linear guides whose components can be purchased separately. The catalog page for the interchangeable linear guide will show separate part number (price and days to ship) for the guide rail and guide block . Of course when ordering parts separately, customers need to specify the same size for both parts (rail and block) if they are to fit together.
E.g. Catalog page 305/2008 catalog.
SEBZ10- Interchangeable Miniature Linear Guides with Standard Block (shipped as a set)
SEBZ10-Guide Block for SEZB10 (can be purchase separately)
STZL10-Guide Rail for SEZB10 (can be purchase separately)
If customers buy two same (size) sets (1rail+1block) but later on decides that only one rail with two blocks is needed, he/she can simply remove a block from one rail and add it to a second rail.
If the linear guide is not interchangeable then this unit can be purchased only as a set and customers should not remove block(s) from the rail and mount them on the different rail as in previous example.
