BD110-1 BD110-1SA Excavator Final Drive Bearing 110x140x28mm Double Row Angular Contact Ball Bearing for Travel Reduction Gearbox

The BD110-1 and BD110-1SA are angular contact ball bearings commonly used in excavator travel reduction gearbox applications. With nominal dimensions of 110 mm inner diameter, 140 mm outer diameter, and 28 mm width, these bearings serve as replacement options for compatible final drive assemblies.

The double row angular contact design is intended to accommodate combined radial and axial loads. Correct bearing selection is essential for supporting rotating gearbox components and maintaining the required assembly alignment.

Material grade, cage type, and bearing clearance must be confirmed for the supplied version.

The double row angular contact bearing structure is designed to accommodate radial and axial forces within a correctly configured bearing assembly.

This type of bearing is used in selected travel reducer systems where bearing dimensions, mounting arrangement, and internal structure must match the original components.

BD110-1 and BD110-1SA bearings are commonly referenced for excavator final drive and travel reduction gearbox repair.

Typical applications include:

• Excavator travel gearbox maintenance
• Final drive bearing replacement
• Travel reducer rebuilding
• Construction machinery transmission repairs

Compatibility depends on the original bearing model and gearbox configuration rather than the excavator model alone.

Before purchasing a replacement bearing, verify the following information:

1. Original bearing model and complete suffix
2. Inner diameter, outer diameter, and overall width
3. Bearing row arrangement and internal design
4. Cage material and clearance requirements
5. Travel reducer model and installation position

Although BD110-1 and BD110-1SA are listed with the same nominal dimensions, dimensional similarity alone does not confirm complete interchangeability.

BD110 series bearings are relevant to excavator repair workshops, construction machinery parts distributors, and final drive rebuilding businesses.

When requesting a quotation, please provide the bearing model, required quantity, original bearing photos, and shipping destination.
