Frequently Asked Questions / FAQ
What are the exact dimensions of RUIST 4052DM?
RUIST 4052DM Bearing: bore d = 260 mm, outer diameter D = 400 mm, width/height B = 140 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RUIST 4052DM carry?
Dynamic load rating Cr = 450 kN and static load rating Cor = 830 kN. These figures let you calculate the L10 service life under your actual radial and axial loads.
Where is RUIST 4052DM typically used?
Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
Can RUIST 4052DM replace a SKF, FAG, NSK or TIMKEN unit?
