Thin Walled Babbitt Bearing Types

Cylindrical Bearings
Cylindrical bearing bushes provide radial shaft support through a hydrodynamic oil film. Bore, length, clearance and lubrication features can be specified according to the equipment design.

 

Flanged Bearings
Flanged bearings provide radial shaft support with an integral flange for axial positioning or locating within the bearing housing.

Thrust Bearings and Pads

Thrust bearings and pads support axial loads and control rotor position. Pad geometry, Babbitt alloy and dimensions are selected according to load, speed, lubrication and rotor requirements.

Split and Half Bearings

Split or half bearings are assembled around the shaft and can be supplied as matched bearing sections. Dimensional matching is important for direct replacement applications.

Customized Bearings

Custom thin walled Babbitt bearings can be manufactured from engineering drawings, CAD files, legacy drawings or worn bearing samples. Bore, OD, length, wall dimensions, oil grooves, key dimensions and clearance can be specified according to the equipment configuration.

Babbitt Lining Thickness
The Babbitt lining is precision-machined to approximately 2–5 mm according to the bearing design and required clearance. Other lining thicknesses can be considered for specific applications.

Dimensional Configuration
Custom bearings can be manufactured with specified ID, OD, length, wall dimensions, key dimensions, oil grooves and running clearance based on equipment drawings or existing components.

 

Babbitt Alloys & Backing Materials
 

Tin-Based Babbitt
Tin-based Babbitt alloys are available for bearing designs requiring a tin-based white metal lining. Alloy selection is matched to load, speed, temperature and lubrication conditions.

 

Lead-Based Babbitt
Lead-based Babbitt alloys can be specified where the equipment design calls for a lead-based white metal lining and the applicable material requirements permit its use.

 

Carbon Steel Backing
Carbon steel backings such as AISI 1020 and AISI 1045 provide the structural support for the Babbitt lining in a range of bearing constructions.

 

Bronze Backing
Bronze backings such as C93200 and CuSn12 can be specified where the bearing design calls for a bronze substrate.

 

Cast Iron and Ductile Iron Backing
Cast iron and ductile iron backings can be supplied according to the bearing structure, housing arrangement and material requirements.

01

Bonding Control

The Babbitt-to-backing interface is inspected to identify bonding discontinuities and other internal defects before machining.

02

CNC Boring

After casting and bonding, the bearing bore is machined to the specified dimensional requirements and running geometry.

03

Finish Machining

The Babbitt surface, oil grooves, key dimensions and other critical features are finished according to the approved drawing.

04

Final Dimensional Control

Critical dimensions are checked before shipment, with dimensional records and inspection documentation available according to project requirements.

05

 

Quality Control & Certifications

 

Babbitt-to-Backing Bond Inspection
