RD-4-240 Continuous Casting Machine Secondary Enclosure Reducer - The RD series reducers combine gear and worm drive, forming a composite two-stage transmission device. The worm gear set of the RD series reducers is produced using professional secondary envelopment worm drive technology. The RD series reducers are a type of planar secondary envelopment reducer, designed for vertical installation. As we all know, the features of planar secondary envelopment reducers include compact and rational structure, small size, high load-bearing capacity, noiseless operation, stable engagement, and relatively long service life. The RD series reducer models include: RD-11.4.5-III Gear-Worm Reducer
