Product Description

SMS M1- Blast Hole OMT Rotary Head Gearbox

SMS M1 is a Blast Hole OMT Series Rotary head Gearbox used for Minerals and Metal Mining. SMS MDD 315 Gearbox is Mounted on 25-30 Ton Excavator. The SMS MDD 400 Gearbox is a specialised drilling solution designed for drilling for blasting in medium and large scale mines. It drills holes with a diameter of 200 mm to 250 mm, withstanding pull-down force of 16,000 kg. It supports both DTH and Rotary drilling methods.

The Gearbox bearing housing is moulded together with gearbox housing to withstand vibration on the bearings holders. can be attached with SMS SA50 Shock absorber for damping vibration that goes to the gearbox. To manage the heavy axial and radial loads of 6-6.5" hammers, weve implemented a four-bearing arrangement on the main spindle. This design minimises spindle run-out and ensures that shock loads are distributed across the assembly, significantly reducing wear on seals and gears. While others use machined bar stock, our 110mm spindle is fully forged.
