Product Details

Double row thrust ball slewing bearings Slewing Ring Bearing

Manufacturers custom-made slewing bearing

The double-row ball slewing turntable bearing can bear radial force, axial force and overturning moment at the same time because it has two rows of steel balls. In order to adapt to the different proportions of the moments, the contact angles range from very small to 90 °. When the diameter of the distribution circle of the steel balls is the same, the total bearing capacity of each row of steel balls is proportional to the diameter of the selected steel ball. Therefore, when the axial cross section and the overturning moment are simultaneously supported under the same bearing section height, the double volley Bearings make better use of section dimensions.

Product process

1,FORGOING

2,Rough turning

Rough and finish turning by CNC lathes. Each process will be
checked according to the drawings. Especially for the oil groove,
ellipse, triangle, outer circle(ring) allowance, inner circle(ring)
allowance, and chamfer must meet the requirements of the drawing.
Well prepared for next steps.

3,Heat treatmeng
Heat treatment will be done according to the types of row material.
Row material must ensure the hardness and heat treatment
deformation are controlled within the qualified range.
4,Rough Machining
A: Surface: Make sure that the machine is cooled in place, control
the surface(plane)bending and parallel difference(tolerance).
Pickling flaw detection for the first product to see whether there
is burning damage or crack.
B: Outer diameter(ring): Control ellipse, triangle and size. When
the product height is large, repeated grinding is needed .
C: Inner diameter(ring): Control ellipse, wall thickness and taper.
If the product height is large, the vertical difference should meet
the requirements.
D: Raceway: Due to the particularity of the product, it is
necessary to grind at a fixed distance and ensure that the cooling
is in place. The flaw detection of wall thickness for the sample
should be qualified not less than 80%.
5,Hardness lathing
Ensure chamfer, oil groove smooth and without vibration.
6, Additional tempering & Teeth processingThe temperature should be within 150 degrees to eliminate interal
stress
7, Finish grinding
100% finish grinding the surface, inner diameter and raceway. The
key function is to improve the products’ accuracy, eliminate the
ellipse and triangle deformation because of the tempering.
8, The second additional tempering & Final grinding
All procedures should be processed strictly in accordance with the
drawings. Special for the temperature difference during tempering;
roughness and angle during raceway processing for outer&inner
diameter should be 100% inspected.
9,Magnetic particle inspection ,Degaussing,cleaning & check appearance
10,Finally Assembling
Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine
Bottle Moulding Machine PET Bottle Making Machine is suitable for
producing PET plastic containers and bottles in all shapes.
