718/710 870 mm 710 mm 74 mm Frequently Asked Questions about 718/710 Angular Contact Ball Bearings（718 / 719 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 718/710 Angular Contact Ball Bearings（718 / 719 SERIES） is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 718/710, FAG 718/710, NSK 718/710. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
The Open / Contact Seal Options engineered for 718/710 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.
To extend the trouble-free lifespan of CHG Bearing 718/710, 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 718/710 over a 710 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.
