LM654649/LM654610D 380.898 mm 285.75 mm Frequently Asked Questions about LM654649/LM654610D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for LM654649/LM654610D 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.
When fitting LM654649/LM654610D over a 285.75 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 LM654649/LM654610D 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies LM654649/LM654610D with a precision bore diameter (d) of 285.75 mm, an outside diameter (D) of 380.898 mm, and a nominal ring width (B) of 139.7 mm. This configuration yields an effective cross-sectional wall thickness of 47.6 mm and an envelope ratio (D/d) of 1.33, delivering compact rigidity for OEM machinery housings.
