LRA:Just like model LR, this model is also designed to be fit into a groove. It is a compact type that can be mounted using fixture model SM or SE and bolts. LRA-Z: A lighter type that uses a resin retainer and is designed to be mounted in the same manner as model LRA. Since it has a groove for installing a seal, a special rubber seal with a high contamination protection effect can easily be attached. In addition, this model is capable of high-speed traveling at 1 m/s. More detailed specifications are available in our digital catalog.
