Description

Deep Groove Ball Bearing for DOOSAN and SUMITOMO Excavators

This BA240-3ASA/BA240-3 deep groove ball bearing is designed for excavators such as DOOSAN HD700-5, HD700-7, 

HD820 and SUMITOMO SH200-2, SH280. With dimensions 240.00 × 310.00 × 32.00 mm, it provides accurate guidance 

and stable support for key rotating components, helping the machine run smoothly under frequent swing, travel and 

working cycles on construction and quarry sites.

High Precision & Chromium Steel Material

The bearing rings and balls are manufactured from high-quality chromium steels (GCR15) and finished with a protective
oil coating. The deep groove design allows the bearing to carry radial loads and a certain amount of axial loads while
maintaining low friction and low noise. This improves resistance to wear and fatigue, allowing the bearing to work
reliably in harsh conditions with dust, vibration and impact.

OEM-Style Replacement & Application

This bearing is made as a replacement option for BA240-3ASA and BA240-3, and is supplied under NSK brand. 

Mounting dimensions follow the original specification so it can be installed directly in place of the old unit without 

modification. It is suitable for DOOSAN HD700-5, HD700-7, HD820 and SUMITOMO SH200-2, SH280 excavators and 

other machines using the same bearing size and design, helping to restore correct clearance and smooth rotation 

of the swing or drive system.

Controlled Quality & Stable Supply

Each BA240-3ASA/BA240-3 bearing is produced under a controlled process and inspected before shipment. 

Dimensional accuracy, internal clearance, noise level and surface finish are checked to keep good consistency

 between batches. Bearings are supplied as new parts with 6 months warranty and regular stock availability. 

They are packed in strong export cartons or wooden cases with oil protection.
