 Single Row Four Point Contact Ball Slewing Bearing--Bearing ungearedLYHY Slewing Bearing Types
LYHY slewing bearings can be divided into the following types as per  their structures:
single row four point contact ball slewing bearing,
single row cross roller slewing bearing,
double row different ball diameter slewing bearing,
three row cylindrical roller slewing bearing and roller/ball combination slewing bearing.
And all these types of slewing bearings can be further divided into bearings without gears, bearings with external gears and bearings with internal gears.

Detailed description of these types slewing bearings

Single row four point contact ball slewing bearings
     This kind of slewing bearings can support high dynamic loads, transmitting axial and radial forces simultaneously as well as the resulting tilting moments. Applications of this kind of bearings are hoisting, mechanical handling and general mechanical engineering etc.
Single row cross roller slewing bearings
     This kind of bearings can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. Main applications of this kind of bearings are hoisting and mechanical handling and general mechanical engineering etc.
Double row different ball diameter slewing bearings
     This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.
Triple row cylindrical roller slewing bearings
     This kind of bearings has high load carrying capacity. Under same loads, this kind of bearings has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers. Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering etc.
Roller/ball combination slewing bearings
     This kind of bearings can support high axial load and low tilting moments. Usually they are large diameter slewing bearings. Applications of this kind of bearings are mining and materials handling etc.

Production Process of LYHY slewing bearings




LYHY Slewing Bearing Packing 
Bearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film;
And then packed with kraft paper and professional belts;
At last, with wooden box totally at the outer packing to invoid the rust or the moist;
We can depend on the customers  demand to be packed;

Transportation:
All LYHY slewing ring bearings can be usually delivered timely, usual production time is 15-50 days based on different slew bearings diameters, sometimes slew rings will be in stock.
Slewing bearings can be offered different delivery terms, such as EXW, FOB, CIF, DDU and so on.
Also, slewing rings can be transported by different transport ways, by express (such as DHL, TNT, UPS, FEDEX and so on), by air, by sea, by truck, by railway and so on.
