382052P5 400 mm 260 mm 255 mm Frequently Asked Questions about 382052P5 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 382052P5 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Every production batch of CHG Bearing 382052P5 Four-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.
When fitting 382052P5 over a 260 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 382052P5, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
