Double Row Ball Structure Slewing Bearing 1. Material: Stainless steel, chrome steel 2. Type: Single Row Ball Structure, Single Row Crossed Roller Structure, Double Row Ball Structure, Three Row Roller Structure and non-standard type. 3. Application: Cranes, excavators, mining/heavy equipments, port/marine machinery; Light industry like food machinery, packing machinery, metallurgical machinery, steel works equipment,
Double-row different diameter ball slewing bearing has three seats.The steel balls and the spacers may be directly arranged into the upper and lower raceways.Two rows of steel balls with different diametera are fitted according to the load.Such open mode fitting features extraordinary convenience.The load angles of both upper and lower races are 90degree,which enable the bearing to bear large axial force,the raceways should be especially designed .
We can manufacture various types of slewing bearings, ranging from 200mm to 4500mm in diameter.Slewing ring bearing, also called slewing bearing, is a bearing that can bear large axial load, radial load and overturning moment. Slewing bearings generally have installation holes, inner teeth, outside teeth, lubricants holes and sealing devices, which enable the main frame structural compact, guide reliable, and easy to maintain.
Three-row roller slewing bearing has three seat-rings,which separate the upper,lower and radial races,via which the load of each row of the rollers may be specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models. Thanks to the large size of its axle and radius,it is sturdy and especially suitable for hearvy-duty machines which require large working radius.such as bucket-wheel excavators,wheeled cranes,ship cranes,ladle turret,
