Installing the LM Roller
The following are examples of how to install different models of the LM Roller. To minimize the gradient of the LM Roller in the traveling direction, provide a reference surface on the mounting surface and press the LM Roller toward it. The mounting reference surface of the LM Roller is opposite of the THK logo marked on the raceway base.
(a) Installing models LR and LR-Z
Use the four mounting bolt holes on the raceway base to mount the LM Roller.
(b) Installing models LRA and LRA-Z
The LM Roller can easily be secured using fixture model SM or SE. SE is provided with a wiper to increase contamination protection effect.
(c) Installing models LRB and LRB-Z
The LM Roller can easily be secured using fixture model SMB or SEB. SEB is provided with a wiper to increase contamination protection effect.
(d) Installing model LRU
Use the four mounting bolt holes built on the raceway base to mount the LM Roller. For the tolerance of the mounting hole, see the figure on the right.
For securing model LRU, we recommend the screws shown in Table1 .
| Model No. | Hexagonal-Socket-Head Type Bolts |
|
|---|---|---|
| Metric screw thread |
Inch screw thread | |
| LRU22.2 | M2.6 | - |
| LRU25.4 | — Note) | 4 UNC |
| LRU38.1 | — Note) | 8 UNC |
| LRU50.8 | M5 | 10 UNC |
| LRU76.2 | M6 | 1/4 UNC |
Note) Do not use a metric bolt. The bolt head will interfere with the roller.
