Single Row Cross Roller Slewing Bearing FAQS

QWhat is Classification of slewing bearings?

ASlewing bearings include four-point contact ball bearings without teeth, outer teeth and inner teeth, double-row contact ball bearings, cross-cylindrical roller bearings, cross-conical roller bearings, and three-row cylindrical roller combined bearings. The four-point contact ball bearing has higher static load capacity. The cross cylindrical roller bearing has higher dynamic load capacity. Cross cone roller bearings can have greater bearing stiffness and higher rotary precision by preloading.

QWhat is Basic structure of turntable bearings

ARotary bearings are usually composed of four parts: inner ring, outer ring, rolling body, and isolation block. Since the core part adopts rotary support, it can bear axial and radial forces at the same time. There are many forms, but the structure is basically the same. From left and right are(upper part): 1. Outer ring(toothed or toothless) 2. Seal with 3. Rolling body(ball or roller) 4. Refueling mouth From left and right respectively(bottom part): 1. plug 2. cone pin 3. inner ring(teeth or no teeth) 4. isolation block or holder 5. installation hole(silk hole or light hole)

QWhat is slewing bearing?

ASlewing bearing is a kind of large bearing with special structure, which can withstand large axial load, radial load and overturning moment at the same time. Under normal circumstances, the turntable bearings themselves are equipped with installation holes, lubricants and sealing devices, which can meet the different needs of various types of hosts operating under various conditions; On the other hand, the turntable bearing itself has the characteristics of compact structure, convenient steering rotation, simple installation and easy maintenance. It is widely used in large rotary devices such as lifting and transportation machinery, excavation machines, construction engineering machinery, port machinery, wind power generation, medical equipment, radar and missile launchers.

QHow to choose slewing bearing cage style and model?

AThe holder type used for turntable bearings has different structural types such as overall holder type, segmented holder type or isolation holder type. The overall holder or segmental holder is made of steel No. 20 or ZL102 cast aluminum alloy. The isolation holder is made of polyamide 1010 resin, ZL102 cast aluminum alloy or QA110-3-1 .5 aluminum bronze. With the continuous development of the material industry, nylon GRPA66 .25 has also been widely used in the design of segmented holder.
