Caution
- Some of the items are scheduled to be discontinued as of end of March in 2023. The manufacturer keep the items produced but they are not available with Misumi.
There are not the replacement items and the plan to resumption of sale. Please check the quotation and order screen for details. - The G dimension (distance from the rail end surface to the mounting hole) is machined so that it is even on the left and right.
The G-dimension may differ from the values listed in the catalog depending on the overall length of the product.
If you have the desired G-dimension, please contact the manufacturer before ordering. - *When ordering multiple shaft types, input multiples of the number of required shafts as the order quantity.
(Example) Required number of axes 2 (-II): number of orders should be "2 pcs., 4 pcs., 6 pcs...."
Required number of axes 3 (-III): number of orders should be "3 pcs., 6 pcs., 9 pcs...."
Product Description
Wide rail width and low center of gravity. It has a lower profile than HSR and is suitable for designs that require Mc moment rigidity.
[Features]
・ The balls roll on the 4 rows of rolling surfaces that have been precision ground on the LM rail and LM block, and the end plates incorporated in the LM block circulate the ball rows.
・ Compact heavy load: Since the number of effective balls is large, high rigidity can be obtained in all directions. Has a wide rail width and can adequately withstand moments with a single shaft.
In addition, since the rail has a large second moment of inertia, it has high lateral rigidity and does not require lateral reinforcement, etc.
・ Automatic adjustment ability: The unique front face combination (DF set) of the circular arc groove has the effect of automatic adjustment, which can absorb the mounting error even if a preload is applied, resulting in highly accurate and smooth linear motion.
