Single-row four-point contact ball slewing bearing（series Q）——Internal Gear

Single- Row four- Point Contact Ball Slewing Bearing applications are:

(1) Engineering ships: dredgers  

(2) feeding machinery: disc feeder, sand mixer

(3) Concrete machinery: concrete pump truck, concrete mixing cloth rod machine, belt cloth

machine

(4) Light Industry Machinery: Beverage Machinery, Bottle Blowing Machine, Packaging Machinery, Filling Machine, Rotary Bottle Finisher, Injection Molding Machine

(5) Special vehicles: bridge detection vehicles, fire engines, gondola machines, flat girder trucks, aerial vehicles, self-propelled aerial work platforms

(6) Crane type: Wheel Crane, Crawler Crane, Portal Crane, Tower Crane, Forklift, Crane, Gantry Crane

(7) Foundation treatment machinery: impact reverse circulation drilling rig, rotary drilling rig, impact rotary drilling rig, rotary drilling rig, reverse circulation rotary drilling rig, positive circulation rotary drilling rig, long spiral engineering drilling rig, submersible engineering drilling rig, static pressure pile Machine, pile driver and so on.

slewing bearings have been widely used instead of original bearings. Construction machinery is the initial application of single row ball slewing bearing is also the most widely used places, such as earth-moving machinery, excavators, dismantling machines, heap picking machines, graders, rollers, tamping machines, rock drilling machines, boring machines and so on.

As supplied slewing rings are generally packed for storage in a covered store and for a period not

exceeding 6 months. Light surface corrosion can usually be removed from exterior surfaces – and it is more important that the raceways are well greased and rust free. Standard commercial solvents can be used to degrease the slewing ring if necessary.

In extreme cases after long term storage bearings may need professionally reconditioning before

installation.When unwrapping, care must be taken not to cut and damage the integral seals.
