Century’s Brewis Maxi Swivel

550 Ton Maxi SwivelFor maximum strength & durability with sizes
from 44 Tons to 550 Tons

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 design achieves a high thrust capacity with a low friction and continuous roller alignment. This bearing type along with two radial alignment bearings is ideal for operating conditions that experience heavy loads, difficulty in establishing or maintaining housing alignment, or shaft deflection. 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
