Full-Ball Type LM Guide, Radial Type, SR Type

[Features]
·A compact type with a low cross-sectional height, ideal for horizontal guides due to the ball contact structure that is resistant to loads in the radial direction
·Since it is an automatic adjustment type that can absorb the parallelism of the 2 axes and the accuracy error of the level reasonably, high precision and smooth movement can be obtained
·The return part of each ball row is designed so that balls circulate smoothly by the guide part of the end plate, so a rolling motion with a small sound can be obtained
·Even with respect to preload and eccentric load, the differential slip of the ball is small, it has excellent abrasion resistance, and it is possible to maintain accuracy for a long period of time
·LM blocks, LM rails, and balls can be handled with stainless steel
·Even if the LM block is pulled out from the LM rail, the ball is held by the holding plate and will not fall off

(i)Remark

The G dimension (distance from the rail flange to the mounting hole) is processed so that it is even on the left and right.
Please note that the G dimension may differ from the values listed in the catalog and CAD depending on the overall length of the product.
When ordering multiple shaft types, input multiples of the number of required shafts as the order quantity.
(Example) If the required number of axes is 2 (-II), then the number of orders will be"2 pcs., 4 pcs., 6 pcs.: "
If the required number of axes is 3 (-III), then the number of orders will be"3 pcs., 6 pcs., 9 pcs.: "

*1)

Length *:

Length Max indicates the standard maximum length of the LM rail.

Allowable static moment *:

1 pc.: Static permissible moment in 1 LM block
2 pcs. in close contact: Static permissible moment when 2 LM blocks are in close contact

Block overall length dimension L:

The block overall length L shown in the dimension table is the dimension when the dust-proof symbol is UU or SS. If other dust-proof parts or lubrication devices are installed, the overall block length L will increase.
The symbol M in the nominal model number indicates that the material of the LM block, LM rail and ball is stainless steel.

Stainless steel products have excellent corrosion resistance and environmental resistance.

*2) 2 types of rails with different mounting hole dimensions are available for SR15 type and 25 type.

Nominal Model Number	Standard Rail	Semi-standard rail
SR15	For M3 (No symbol)	For M4 (Symbol Y)
SR25	For M6 (Symbol Y)	For M5 (No symbol)

Please be careful about the mounting hole dimensions of the LM rail when replacing it with the SSR type.

*3) The basic rated load in the dimension table is the value for the load in the radial direction.
