HM265049D/HM265010 523.875 mm 368.3 mm Frequently Asked Questions about HM265049D/HM265010 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing HM265049D/HM265010 Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
To ensure optimum performance of CHG Bearing HM265049D/HM265010 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 368.3 mm bore. For the 523.875 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To extend the trouble-free lifespan of CHG Bearing HM265049D/HM265010, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
When fitting HM265049D/HM265010 over a 368.3 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
