HRU445(G) 540 mm 350 mm 45 mm Frequently Asked Questions about HRU445(G) HRU Series Crossed Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HRU445(G) HRU Series Crossed Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 350 mm bore. For the 540 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Standard batches of CHG Bearing HRU445(G) conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Absolutely. The CHG Bearing HRU445(G) HRU Series Crossed Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HRU445(G), FAG HRU445(G), NSK HRU445(G). It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Built for demanding industrial environments, the HRU445(G) HRU Series Crossed Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
