[!] Anti-rust oil is applied at the time of delivery. [!] Dr = 3 or 4 is not available for LMUW-N, LMUWM-N, and LMUWR.
[!] No seal supplied for dr = 3 or 4. [!] No Seal Type has lower sliding resistance (0.4 ～ 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 LMUW−N10, it will be either LMUW−N10 or LMUW10−N.
