RS-320A - Right angle input type of the precision reduction gear.
- Brand: Nabtesco
- Product Code: RS-320A
Description: The RS series is a table type design featuring a low profile, hollow shaft through hole, along with a right angle input. Improving on the RV series excellent load support, the RS series can support a maximum of 9 tons. In addition to fittings compatible with major servomotors and sealed with grease before shipping. The table type design allows for significant reductions in cusomer design and assembly process(cost).
