Delroyd series BX Speed Reducers for conveyor drives feature exceptionally high overhung load capacity. This design advantage usually permits selection of a smaller drive unit for a given load. Drywell construction around the output shaft helps prevent leakage from above. Series BX Conveyor Drive Units incorporate the Delroyd involute helicoid thread form which permits simple, accurate gearing adjustments without running in expensive matched, lapped worm and gear sets.
