Model RU Roll Forming Machines
The model RU (universal drive) roll-forming machine is a high-speed, high-quality machine driven to perfection by worm gear speed reducers through universal drive couplings. Capable of speeds up to 600 rpm, this is the ideal machine for the high-volume manufacturer of roll-formed profiles, tubular shapes, metal building roofs, sidewall panels, and other similar products.
Features
Standard Features:
- Micrometer adjustment of top shafts
- Hardened alloy steel roll shafts with precision shoulder arrangement and double Timken taper roller bearings on both main drive housing and outboard support
- Universal couplings to double output pinch roll worm gear reducers (unequal ratios available from 1.1:1 to 2.5:1)
- Hardened tool steel, roller-type entry side guides
- Welded steel base with coolant troughs and machined base top, alignment key and cross-keyed for precision alignment of outboard support
