TYPE 1 (Api Box / Clevis for MAXI Rigs)
The increased range of Maxi-Rig swivels is designed to better fit the capacities of the most common rig manufactures.

Type 1 swivels offer an API box connection at the leading end and a clevis connection at the trailing end. The rigid connection allows more straight forward pushback, but it also places a greater side load on the swivel.

This special series is designed with service in mind. The seal cover is removable and all seals can be replaced in the field without need for major disassembly. Factory service can be scheduled to keep the Maxi-DUB Swivel® running smoothly; this preventative maintenance will keep the swivel operating longer.

TYPE 7 (API Pin / Clevis for MAXI Rigs)
Type 7 Maxi-DUB Swivels® with an API pin connection (to the reamer or hole-opener ahead of the swivel) are a special-order option. The specifications are identical to the standard Type 1 Maxi-DUB Swivels®. Custom threads are available. Call for more details.

TYPE 8 (API Box / Lug for MAXI Rigs)
Special applications call for special solutions: Type 8 Maxi-DUB Swivels® have been built to customer specifications to fit shackle connections. Otherwise specifications are identical to the standard Type 1 Maxi-DUB Swivels®. Call for more details.
