Hydrodynamic Bearings for Turbomachinery | Journal, Thrust and Tilting Pad Bearings

Hydrodynamic Bearing Manufacturer

As a hydrodynamic metal bearing, bearing components and assembly manufacturer and repairer in S.Korea, we have been providing fixed geometry bearings and tilting pad bearings to wide range of oil and gas and power generation industry serving companies with nuclear plant certified bearing quality. Our hydrodynamic bearings serve renewable energy, nuclear energy, thermal  requirements in the market including nuclear industry, thermal, petrochemical industry and other turbomachinery application that requires critical rotational support.

Our two manufacturing factories are near Busan port, South Korea and are both certified of ISO 9001 and ISO 14001. The R&D center which is also based in Busan is where a team of engineers co-develop and co-design bearings, and bearing material with their clients, and what produced multiple design and manufacturing patents for hydrodynamic bearings. We are one of the few suppliers that was able to meet the expectations and requirements of all six core power plants in South Korea under KEPCO, supplying all of the bearings required for one of the new nuclear power plants in South Korea. We carefully design each hydrodynamic bearing by going over all the design parameters for optimum offset, preload, steady load, dynamic load, L/D ratio and clearance for each application.

Our patented manufacturing method for radial bearing and thrust bearings, patented design for bearings with load and eccentricity requirement, and enhancement of bonding strength allow us to produce quality parts for applications that require high precision, strength, support and finishing quality.

Our core competencies include designing and manufacturing, as well as repairing or rebabbitting of fluid film journal bearings, and thrust bearings, tilting pad bearings, turbine bearing assemblies, compressor bearings, white metal babbitt bearings, PEEK bearings for high temperature and bearing components.

Hydrodynamic Bearings Advantages

Hydrodynamic bearings are used for larger, faster and stronger rotating equipment that requires stronger support for the rotating parts. These include steam turbine, gas turbines, marine shafts, pumps and motor that run on speed higher than 3000 RPM, or machinery running over 500 HP. Hydrodynamic bearings provide support for turbomachinery with a longer life time than ball bearing or roller bearings from the lubrication that prevents contact between the rotating parts of the bearings. In addition, hydrodynamic bearings can operate through the critical speed while maintaining optimum stability and suppress vibration while reducing noise.

Applications of Hydrodynamic Bearings

Applications of our hydrodynamic bearings include gas turbines, steam turbines, generators, heavy machinery rotary shafts with high speed requirements, hydroelectric turbines, large and heavy pumps, compressors, large engines, and etc.

Fixed Geometry Bearings

Fixed Geometry Journal Bearings

Hydrodynamic journal bearing designing and manufacturing capability includes multi-lobe bearings, elliptical bearings, pressure dam bearings, offset half bearings, and tilting pad bearings considering the rotor dynamic characteristics. Our hydrodynamic journal bearings are used for gas and steam turbines, gearboxes, compressors and pumps.

Fluid Film Thrust Bearings

Our fixed geometry thrust bearing capability includes plain thrust bearings, tapered thrust bearings, side-walled tapered thrust bearings that considers the design requirements.

Hydrodynamic Tilting Pad Bearings

Tilting pad bearings allows bearing pads inside to move about a pivot, following the movement of the shaft to retain its own equilibrium position, eliminating potential instability. Our tilting pad bearings are custom manufactured to have different number of pads, preload, pivot offset, type of pivot and orientation of the pads (LBP-load between pivots and LOP-load on pivots). Tilting pad journal bearings are applied to high speed and high performance compressors, as well as steam turbines, gas turbines and pumps, boosting dynamic stability of the rotors. We can supply the full customized pad bearing assembly, as well as the parts inside such as the casing and the pads.

Nuclear and Thermal Power Plants – Gas and Steam Turbine and Generator Bearings

As one of the first company in Korea to manufacture and supply hydrodynamic bearings to the Nuclear industry in the beginning and as a Q level quality holder from KEPCO Nuclear power, we have been contributing to the nuclear industry, hydroelectric industry, thermal industry and other power generation industry with our generator bearings (journal and tilting pad), and turbine bearings and assemblies (journal and tilting pad). One of our specialty is the Babbitt bearings for the main turbine shafts. We manufacture all bearings in house and provide refurbishing and rebabbitting of your current bearings in house.

Repair, Analysis and Rebabbitting

Our manufacturer is a quality class I certificate holder for nuclear power plant services that have an in-depth experience providing analysis, repair or rebabbitting services on-site for reactor coolant pumps and turbo-machinery repairs. Our 2 manufacturing and R&D facilities provide rapid bearing restoration that minimizes our clients’ operation costs for power plants. Because rebabbitting restores the bearings close to its original state, lots of clients choose to rebabbitt or repair the bearings instead of getting a new bearing manufactured. Find more information about our hydrodynamic bearing rebabbitting services in the Bearing Repair, Analysis and Rebabbitting tab.
