INA combined axial and radial bearings are bearings that can support both radial and axial loads. The design of these bearings is characterized by a structure that ensures good support and stability in both axial and radial directions.
Structural features and working principle
The structural features of the INA combined axial and radial bearing include:
Bearing ring: The bearing ring of the radial bearing is fixed to the axial end through the mounting hole of the axial bearing.
Locking ring: A positive locking connection between the radial bearing and the axial bearing is achieved by a locking ring, ensuring that the two cannot rotate relative to each other in the circumferential direction, but axial displacement is allowed. This bearing is particularly suitable for the following scenarios:
Radial space limitation: When the radial space of the equipment is limited and a compact bearing design is required, this combined bearing can provide an effective solution.
High speed and heavy load: In applications that need to withstand high speeds and heavy loads at the same time, this bearing can provide stable support and low friction.
Insufficient lubrication: For environments with poor lubrication conditions, this bearing design can effectively reduce the impact of insufficient lubrication
Maintenance and maintenance recommendations
In order to ensure the long-term stable operation of the INA combined axial and radial bearing, the following maintenance measures are recommended:
Regular inspection: Regularly check the internal clearance and lubrication status of the bearing to ensure that it operates within the design range.
Proper lubrication: Use appropriate lubricants, such as thin grease or oil mist, to ensure that the bearing can still maintain good lubrication under high speed and high load conditions
INA combined axial-radial bearings represent a paradigm shift in load management, merging radial support and axial thrust capacity into a single compact unit. Designed to replace traditional bearing pairs (e.g., radial ball + thrust washer), these bearings deliver 40% space savings, 30% weight reduction, and eliminate alignment errors in applications ranging from robotic joints to solar trackers and medical scanners.
