2-4-9 Dust Proof Accessories
End seals and standard accessories fixed on both sides of the block can prevent dust from entering the block, so
the accuracy and service life of a linear guideway can be maintained. Bottom seals are fixed under the skirt portion
of the block to prevent dust from entering. Customers can order bottom seals by adding the mark “+U” followed by
the model number. Sizes 9, 12 and 15 provide bottom seals as an option, but size 5 and 7 do not offer the option due
to the space limit of H1. Note that “H1” would be reduced if bottom seal’s attached, interference between block and
mounting surface should be awared of.
