Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 020.60.3550 Double-Row Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 020.60.3550, FAG 020.60.3550, NSK 020.60.3550. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 020.60.3550. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
When fitting 020.60.3550 over a 3272 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.
To ensure optimum performance of CHG Bearing 020.60.3550 Double-Row Ball Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 3272 mm bore. For the 3828 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
