Frequently Asked Questions / FAQ
What are the exact dimensions of RUIST HN1021?
RUIST HN1021 Bearing: bore d = 105 mm, outer diameter D = 145 mm, width/height B = 20 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RUIST HN1021 carry?
Dynamic load rating Cr = 103500 kN and static load rating Cor = 77000 kN. These figures let you calculate the L10 service life under your actual radial and axial loads.
Where is RUIST HN1021 typically used?
Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
Can RUIST HN1021 replace a SKF, FAG, NSK or TIMKEN unit?
