Type 3MB Oilfield Swivel
Brand: King Oil ToolsFor Mineral Exploration - Deep Water Wells
The 3MB swivel is rugged, compact and dependable. Made of high-grade alloy steel, it has a high capacity proportionate to its weight. The packing unit consists of a stuffing box and Chevron V-Type packing. The entire packing assembly can be replaced within a few minutes without “breaking-out” any connection.
Built to “oil field standards,” the swivel features an upper taper bearing, spherical roller main bearing and a lower radial ball bearing. A bearing adjusting nut is standard. This construction makes this swivel more dependable and more rugged than any existing swivel now offered by rig manufacturers.
Four large trunnion pins are provided for rigs equipped with pull-down yokes. Two-inch trunnion pins are standard. The 10-3/4” shoulder dimension of the pins allows replacement in existing rigs equipped with yokes.
Features- Large watercourse to permit circulating more drilling fluid
- Oil lubrication of bearings
- Oil seals to retain fluid and protect bearings
- Bearing adjusting nut
- Chevron packing and washpipe easily changeable without breaking connections
