Load Ratings in All Directions and Static Permissible Moment (KR)
Load Rating
LM Guide Unit
Model KR is capable of receiving loads in four directions (radial, reverse radial and lateral directions).Its basic load ratings are equal in all four directions (radial, reverse radial and lateral directions),and their values are indicated in Table3 on Detailed information for each model numbers [load rating] .
Ball Screw Unit
Since the inner block is incorporated with a ball screw nut, model KR is capable of receiving an axial load. The basic load rating value is indicated in Table3 on Detailed information for each model numbers [load rating].
Bearing Unit (Fixed Side)
Since housing A contains an angular bearing, model KR is capable of receiving an axial load.The basic load rating value is indicated in Table3 on Detailed information for each model numbers [load rating].
Equivalent Load (LM Guide Unit)
The equivalent load when the LM Guide unit of model KR simultaneously receives loads in all directions is obtained from the following equation.
| PE | Equivalent load (N) : Radial direction : Reverse radial direction : Lateral directions |
|---|---|
| PR | Radial load (N) |
| PL | Reverse radial load (N) |
| PT | Lateral load (N) |
Static Permissible Moment (LM Guide Unit)
The Inner block is capable of receiving moment loads in all three (3) directions. Table4 shows static permissible moments in the MA, MB and MC directions.
