KG055AR0 Bearing Structural Features & Performance Benefits
Optimized Thin Section Design: With a cross-section of only 1" width and large 5.5" bore diameter, this bearing provides maximum space efficiency while maintaining structural integrity.
Superior Load Capacity: Engineered to handle significant combined loads with radial dynamic load rating of 7,192 lbf and exceptional axial static load capacity of 16,240 lbf.
High Precision Construction: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore and OD tolerance: -0.0010" to 0") ensuring smooth operation and minimal runout.
Premium Material Selection: Features chrome steel rings and balls with brass cage for durability, corrosion resistance, and stable performance across the operating temperature range of -30°C to 110°C.
Enhanced Moment Capacity: Substantial static load moment rating of 35,570 lbf provides excellent stability in applications subject to overturning moments.
