013.40.1250.11 1400 mm 1090 mm 1350 mm 1150 mm 120 mm Frequently Asked Questions about 013.40.1250.11 Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 013.40.1250.11 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 013.40.1250.11 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
When fitting 013.40.1250.11 over a 1090 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.
For international ocean and air freight, CHG Bearing packs 013.40.1250.11 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
