Journal (radial) bearings
Tilt pad journal bearings
Four- or five-pad radial bearings for high-speed turbomachinery — stable at speed and less sensitive to load direction than sleeve bearings.
Ø 25 – 750 mm · point, line, ball-and-socket pivots
Maxalign® bearings
Ball-and-socket pivot for large shafts: high stiffness and misalignment capability for generators and large turbines.
Shafts 300 mm and up · trailing edge cooling
Flexure Pivot® journal bearings
One-piece pad, pivot and retainer for high-load, high-speed small shafts — no pivot wear or pad flutter.
Low profile · drop-in upgrade for sleeve bearings
Fixed profile journal bearings
Medium and thick wall sleeve bearings: plain sleeve, multi-lobe, lemon bore (elliptical), pressure dam and offset half.
Pressure-fed or oil-ring lubrication
MLSF® bearings
Multi-lobe semi-floating bearings for turbochargers and small high-speed machines — long life with low vibration.
Also with Flexure Pivot tilt pads
Thrust (axial) bearings
Self-equalizing tilt pad thrust bearings
Equalizing links share the load between pads and absorb misalignment between bearing and collar.
Modular CQ range
Directed Lubrication thrust bearings
Oil fed to each pad instead of a flooded housing — typically half the power loss, cooler pads, no shaft seal rings.
Modular MS range
Flexure Pivot® thrust bearings
Tilt pad performance in the space of a taper land face — more load capacity without a larger envelope.
Taper land thrust bearings
Thrust plates with simple or compound taper faces for low loads, limited space and negligible misalignment.
Babbitt, copper, bronze or polymer faces
Hidrax® HT thrust bearings
Ceramic / cermet tilt pad thrust bearings for high-temperature electric submersible pumps.
Oil bath 300 °C and higher · 8 MPa rated load
Combined thrust & journal bearings
Thrust and journal bearing in one unit where axial space is limited.
Assemblies, dampers & materials
Horizontal bearing assemblies
Custom journal or journal/thrust assemblies, self-contained or fed from an external oil system.
Compressors · motors · pumps · marine line shafts
Vertical bearing assemblies
Thrust and journal assemblies for vertical pumps, motors and generators.
Air, water or forced-oil cooling · hydrostatic lift
Integral squeeze film damper (ISFD®)
Bearing and damper in one unit to move critical speeds and suppress subsynchronous vibration.
New machines and drop-in retrofits
TruTech® polymer bearings
Polymer-lined and solid polymer bearings for high temperature, thin films, water or process-fluid lubrication.
Up to 250 °C · electrically insulating
Aluminium tin bearings
AlSn-lined pads as a drop-in for babbitt, with up to 60 % more load capacity.
Copper-free option
Ceramic & cermet bearings
Hard surfaces for abrasive, corrosive or very hot duties such as water injection pumps.
Up to 400 °C
Active magnetic bearings
Radial magnetic bearings
Four electromagnets hold the rotor centred — no contact, no lubricating oil.
Axial magnetic bearings
Opposed disc electromagnets locate the rotor axially on a thrust collar.
RDS® auxiliary bearings
Bushing-type landing bearings that carry the rotor at standstill or after a system fault.
Full-speed landing tested
Position sensors
Radial and axial rotor position feedback for the controller.
Inductive, eddy current or capacitive
Sealed & canned magnetic bearings
For immersion in process gas or liquid — canned versions for H₂S, chlorides and sand.
AMB controllers
Zephyr®, Chinook® and Elephanta® digital controllers with remote commissioning and condition monitoring.
Machines from 50 kW to 80 MW
Seals & engineering services
Brush seals
Compliant bristle seals that hold a small leakage gap in turbines and compressors; replaceable bristle pack.
Up to 650 °C · 20 bar per row · Ø 19 – 3,050 mm
Rotordynamic analysis
Lateral and torsional analysis to diagnose vibration and select the right bearing and seal.
Bearing & material testing
Bearing and material tests in Waukesha's own laboratories.
