Rated Load and Static Permissible Moment in Each Direction

Rated Load

P L P R P T P T • LM guide section The KR can carry loads in all directions, i.e., the radial, inverse radial, and two lateral directions. The basicrated load is the same in all four directions, and their values are shown in Table 2 on page 7. ? Ball screw section The KR can carry loads in the axial direction since it incorporates a ball screw in the nut block. The basic ratedload values are shown in Table 2 on page 7. ? Supporting bearing The KR can carry loads in the axial direction since it incorporates an angular bearing in housing A. The basicrated load values are shown in Table 2 on page 7.

Equivalent Load (LM guide)

When loads are simultaneously applied to the KR’s LM guide in all directions, the equivalent load is obtained by the following equation: P
E = P
R (P
L ) + P
T P
E : equivalent load(N) · in radial direction · in inverse radial direction · in lateral directionsP
R : radial load(N)P
L : inverse radial load(N)P
T : load in lateral directions(N)
