Generator Bearings

Heavy duty self aligning bearings for generators

TRI can cast large bearings for turbines and generators. Our newest centrifugal casting machine (video) can cast a bearing diameter up to 70" and approximately 20,000 lbs. Our bearings have proven to be reliable while being easy to setup and maintain.

TRI generator bearing can be made with double-insulated saddle blocks with each layer providing over 500 megohms resistance.

For very heavy rotors, the lower pads or lower half can be supplied with lift oil grooves.

TRI bearings are tailored to suit the needs of ne applications or as drop-in retrofit in older units. TRI bearings are installed for electrical generation throughout the country.
