Precision Excavator Bearings 184BA-2251 Single Row Angular Contact Ball Bearing
184BA-2251 is an angular contact ball bearing used in excavator travel slewing and wheel-side reduction systems.
Product Positioning and Core Values
The 184BA-2251 angular contact ball bearing is specially designed for core components such as excavator travel systems and slewing motors, focusing on low-speed, high-impact, and combined load conditions. Through precise structural design and material optimization, it can bear both radial forces and axial impacts simultaneously, ensuring stable transmission of construction machinery in harsh environments such as mud, dust, and high-frequency vibration. It is the "impact-resistant core component" for power transmission of excavators.
Supports continuous output torque of travel motors, meeting the operational requirements of 30-ton excavators
Limiting Speed
≈ 3500r/min under grease lubrication (conventional)
Adapts to the medium and low-speed operation characteristics of excavators (travel speed ≤ 5km/h, slewing speed ≤ 10r/min)
Technical Advantages and Process Highlights
Combined Load Adaptation Design: With an optional contact angle of 15°~25°, the axial load capacity is increased by 20%, which can accurately match the combined loads during excavator start-up (instantaneous axial thrust) and slewing brake operation (radial inertia force + axial impact force). This reduces premature failure of the bearing caused by "force system imbalance".
Precision Manufacturing for Reliability: The ring raceway is processed by ultra-fine grinding technology, with a surface roughness of Ra ≤ 0.08μm, reducing friction and wear between balls and raceways. The ball roundness error is ≤ 0.5μm, achieving "zero-clearance" transmission, reducing abnormal noise and energy loss, and lowering vibration values by 15% under mining conditions.
Enhanced Protection for Harsh Working Conditions: An optional sealing design (protection class IP65) resists dust and muddy water intrusion through a double-lip seal structure, extending service life by 50% under mining conditions. The bearing steel is strengthened by carburizing, with a surface wear-resistant layer thickness of ≥ 0.2mm, which can resist scratches and wear from sand and gravel particles, improving wear resistance by 25%.
Application Scenarios
Core Application Components
Travel system: final drive gearbox, wheel-side reduction mechanism (bearing track driving torque and resisting ground impact)
Slewing system: slewing motor output, reducer (balancing centrifugal force during rotation and axial impact during braking, ensuring rotational stability)
Application Fields
The 184BA-2251 angular contact ball bearing, with its combined load adaptation design (adjustable contact angle), precision manufacturing process (surface roughness Ra ≤ 0.08μm), and protection for harsh working conditions (IP65 sealing + carburizing strengthening), performs excellently in core components such as excavator travel, slewing, and wheel-side reduction. It can significantly improve equipment reliability, extend maintenance intervals, and bring direct economic benefits to customers in scenarios such as mining, ports, rail transit, and overseas infrastructure.
