Mangrovite – McKay
McKay (now Barlow) represented Mangrovite and it’s range of AC geared motors for many years.
The available range was quite extensive, starting at 0.06kW and going all the way up to 30kW.
Gearbox frame sizes:
2000 (38mm output shaft)
4000 (45mm output shaft)
6000 (65mm output shaft)
8000 (65mm output shaft)
Some of the technical details of the Mangrovite gearbox were quite impressive:
Gears and pinions were manufactured from nickel chrome case hardening steel, double quenched and tempered. In addition, they were de-burred and profile ground where necessary to improve accuracy. All bores and bearing seatings were ground to fine tolerances.
Output shafts were manufactured from 60-70 ton nickel molybdenum steel and ground on all operating diameters.
Gears were keyed to shafts for positive drive, and ease of service in the field in the event of exceptional overload.
The majority of gear units were foot mounted, although flange mount was available on request.
Mangrovite – Still Available
As you can see from the below dimension drawings, the Mangrovite gearbox design is very similar to the Barlow design, allowing for bolt-in replacement in many cases.
