What was said previously for table TR is also valid for the series made of light alloy. However, differences as far as sizing and load rating are present. The height A is smaller for type TRL1,
TRL3 and TRL6 series (see dimension table). The series TRL6 has two additional sizes with respect to its cast iron counterpart TR6. While the series TRL3 includes four additional sizes. The load ratings are lower than series TR and so is the weight. Therefore, the table TRL are indicated for movements with high acceleration since their mass is lower and consequently the inertia. Tables of series TRL are supplied with attaching holes
