Regarding the product:
(1) The product range of INA thrust angular contact ball bearings is very wide
Bearing arrangement that can meet the high dynamic operating conditions of screw driveDesign requirements include high precision, high load-bearing capacity, high stiffness, low friction, easy installation, and maintenance free or minimal maintenance. Through thisBy considering comprehensive and ideal products, specific solutions can be obtained to meet the technical and practical requirements of bearing arrangement in screw driveEconomic requirements.
(2) Single column and multi column design
There are several types of thrust angular contact ball bearings, including single row, double row, and triple row, all of which are ready to use units. They are inseparable and contain geometric rulersStable thick walled outer ring, ball bearings, cage components, and one or two inner rings. In some series, there are through holes on the outer ring flangeCan be installed on adjacent structures. These bearings have inner and outer rings that match each other, so when using precision locking nuts to lock the bearing rings, the bearingsIt can achieve pre tightening setting.
(3) Radial and axial load-bearing capacity
Due to its 60 ° contact angle, the bearing can withstand not only radial forces but also high axial forces.Double row, bolt mounted thrust angular contact ball bearings ZKLF are directly installed in adjacent structures or radial positioning holes through bolts. As a resultIt can eliminate the need for additional bearing end caps and related matching work.In order to facilitate the removal of the bearing from the positioning hole, a disassembly groove is designed on the outer circumference of the bearing. Equipped with detachable flat head screwsThe radial and axial threads make re lubrication work easier.
