Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face.
On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special mill babbitt which is peened in place and bored to fit the trunnion.
In all cases a low bearing pressure is maintained to assure freedom from overheating, long life and minimum maintenance. They are designed to provide support to the mill proper, its media and pulp load.
Trunnion bearings are generally supplied with seals for use with a circulating oil lubrication system. They can be designed to accommodate block grease or oil with wool waste.
For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication.
In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.

Straight subs: Used to connect drill stem members that have a similar OD.

Reduced-section sub: Used to connect drill stem members that have different diameters that warrant the cross-sectional change necessary to accommodate different connections.

Saver sub: Used to extend the life of the rotary kelly by taking the connection wear each time it is made up to a drill stem component.

Bit sub: Size availability ranges from 3 1/8 in to 11inch OD and 36in to 48in length.

Lift sub: A lift sub enables the safe, efficient handling of straight OD tubular, such as drill collars, shock tools, jars, directional equipment, and other tools, by using the drill pipe elevators.

Top drive sub: Top drive subs serve as the sacrificial element between the drill string and the top drive, reducing repair and maintenance costs.
