Червячные редукторы NRV
Редукторы червячные типа NRV за счет низкого уровня шума и возаимозаменяимости с иностранными аналогами очень удобны в эксплуатации. Данный тип редукторов относится к одноступенчатым редукторам, при этом он очень копактен и расчитан на высокие нагрузки. Соотношение цены и качества позволяет ставить червячный редуктор NRV на первые места по прадажам по всей России.
