Features

Structure and Features

With the Model RSX, balls roll in two rows of raceways precision-ground on an LM rail and an LM block, and end plates incorporated in the LM block allow the balls to circulate. The Model RSX uses two rows of raceways, and it can help reduce the size of a device because it has more compact outer dimensions than models with four raceways. Despite being compact, its ball contact structure is capable of receiving loads in all directions, and it can be used individually in locations where moments are applied.

Ultra Compact

The Model RSX has one raceway on either side of the LM rail, and its compact design with low cross-sectional height allows it to be installed in locations with limited space.

Corrosion Prevention

The Model RSX uses an LM block, LM rail, and balls made of stainless steel, which has high corrosion resistance.

Retains Balls

The Model RSX incorporates a ball-retaining wire that prevents balls from falling out when the LM block is removed from the LM rail, making mounting easy.

Flatness of the LM Rail and the LM Block Mounting Surface

Since the Model RSX has Gothic-arch grooves, any precision errors in the mounting surface may negatively affect its operability. Therefore, we recommend using it on mounting surfaces made with high precision.

Table1 Flatness of the LM Rail and the LM Block Mounting Surface

Unit: mm

Model No.	Flatness error
RSX 5	0.015/200
RSX 7	0.025/200
RSX 9	0.035/200
RSX 12	0.050/200
RSX 15	0.060/200

Note1) As there are many cases in which the mounting surface precision is affected by a number of factors, we recommend using 70% or less of the values shown.
Note2) The above figures apply to normal clearances.When using two or more rails with C1 clearance, we recommend using 50% or less of the values shown.
