Caged Ball LM Guide, Low Floor Wide Rail SHW Type (Part Numbers)

Caged Ball LM Guide, Low Floor Wide Rail SHW Type

THK

THK

Wide rail width and low center of gravity. It has a lower profile than SHS and is suitable for designs that require Mc moment rigidity.

[Features]
・ A wide-type, high-rigidity LM guide that uses a ball retainer to enable low noise, long-term maintenance-free operation, and excellent high-speed performance.
・ The SHW type with a low center of gravity and a wide LM rail width is ideal for places where space saving is required and Mc moment rigidity is required.
・ Since each ball row is arranged with a contact angle of 45° so that the load rating is the same in the 4 directions (radial direction, reverse radial direction, lateral direction) acting on the LM block, it can be used in any position. It can be used for a wide range of purposes.
・ The unique front face combination (DF set) of the circular arc groove enables the automatic adjustment capability to absorb the mounting error even if a preload is applied, resulting in a highly accurate and smooth linear motion.
・ The ball retainer eliminates mutual friction between balls and retains lubricant oil (agent) so that dust is unlikely to occur.

(i)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...."
