Manufactured Products by TRI Transmission and Bearing Corp.

Industrial Brakes

TRI manufactures heavy-duty brakes for fluid drives and other industrial equipment. TRI brakes are designed for easy maintenance and a reliable hydraulic system. The feature that sets the TRI brakes apart from our competitors is the hydraulic pump which retains clamp pressure even if small leaks occur in the brake lines.

Our heavy duty hydraulic brakes are custom made for your equipment. Contact a TRI engineer for more information about brakes and other manufactured products.

Generator Fans

Heavy-duty Fans

TRI Manufactures heavy-duty fans for air cooled generators. Our fans are machine from a single solid steel forging. There are no welds to fail. These fans have excellent strength and vibration characteristics.

Our generator fans are custom made for your equipment. Contact a TRI engineer for more information about fans and other manufactured products.

Babbitted Seals

Fixed Babbitted Seals, Labyrinth Seals and Floating Seal Rings

TRI Manufactures Babbitted seals for rotating equipment. Our seals have steel backing and precision machine Babbitt bores. We have both standard sizes and custom designs. Our designs can come with custom labyrinth teeth configurations, anti-rotation pins and width customized to your application. Our seals are used extensively throughout many industries.

Contact a TRI engineer for more information about Babbitt Seals and other manufactured products.

Lube Oil Systems

Fluid drives and bearings require dependable oil systems. The lube oil systems are critical components that can shut down plants for weeks or even months if they fail. The cost of unscheduled maintenance outages greatly exceeds the cost of lube oil systems.

TRI has been in the business of providing equipment for bearings and fluid drives for over 40 years. We understand that what is required for reliable systems with redundant backups. Consequently, TRI has provided many customers over the years with new or improved oil systems.

Here is a list of the lube oil system that we have built in the past:

  1. Lift oil system for a large generator. These system provided over 3000 psi to ensure no contact between the heavy rotor and the bearing surfaces during startup and shutdown. A hydrodynamic bearing depends on the rotation of the shaft to develop an oil film. Until this film is developed, the journal can rub and wipe in the bearing bore. This often happens during start up, shut down, or on turning gear.  TRI makes a high pressure lift oil system with modified bearings to reduce the wear at low speed. Lift oil system also have the added benefit of reducing the power required to turn the shaft slowly turning generator/turbine
  2. An emergency lube oil system for a chemical facility. This system used UPS and VFD technology so that readily available AC motors could be used during power outages.
  3. Fluid drive oil system that provides both lubrication to the bearings and circuit oil for the hydrokinetic coupling.
