RKS.062.20.0644 The package,: Inside packaging: plastic film + kraft paper + blue tape; Outside packaging: standard export free-fumigation wooden case. we can assure that the bearing shipping by sea or by air.
The delivery time:25-35 days
Generally, RKS.062.20.0644 slewing bearings are large-size rolling bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction. They can perform both slewing (oscillating) movements as well as rotational movements.
Basically, RKS.062.20.0644 slewing bearing consists of an inner ring , an outer ring and rolling elements−balls or cylindrical rollers−that are separated by polyamide spacers .The rings, one of which usually incorporates a gear , are provided with holes to accommodate attachment bolts. The holes may be threaded.Двухрядный шарикоподшипник с четырехточечным контактом (без зубьев)
Generally, only the raceways in the rings are hardened and precision- ground. Integral seals made of acrylonitrile- butadiene rubber (NBR) keep the lubricant in, and contaminants out of the bearing.
