Maxi Swivels for rigs over 80,000 lbs.
Century’s Brewis Maxi Swivel

For maximum strength & durability with sizes from 44 Tons to 550 Tons

550 Ton Maxi Swivel

This one-piece shaft and clevis is designed especially for extreme conditions with 4145 high strength heat treated steel.   Our maxi swivel line incorporates the highly regarded “SKF explorer spherical roller thrust bearing.”   This bearing handles the load in either dynamic or static situations.   Radial load bearings on either end of the rotating shaft extend the performance life of the swivel.

Features:
  • Patented sealing system keeps bentonite out and still allows for power greasing
  • Side grease point allows for easier greasing
  • Box to clevis design
