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
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 processing

The 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.
