[!] Anti-rust oil is applied at the time of delivery. [!] Dr = 3 or 4 is not available for LMU-N, LMUF-N, and LMUM-N.
[!] No seal supplied for dr = 3 or 4. [!] No Seal Type has lower sliding resistance (0.4 to 1.2 N) and slides smoothly. Separate dust-proofing measures are necessary to keep the dust entering into sliding parts.
" ! " There are 2 engraving types for products without seals. Example: Part Number: For LMU−N10, it will be either LMU−N10 or LMU10−N.
