Product Description
High quality and high precision rotary bearing
High quality and high precision rotary bearing belong to slewing bearing. They are axial and radial combined cylindrical roller bearings,including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial preload,for the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent roller and rings generating collisions which influence bearing accuracy.
In addition to standard parts, we undertake a variety of non-standard workpiece processing
Product Process
1 Forging raw material
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.
4 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.
5 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%.
6 Hardness lathing
Ensure chamfer, oil groove smooth and without vibration.
7&8 Additional tempering & Teeth processing
The temperature should be within 150 degrees to eliminate interal stress
9 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.
10&11 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.
12 magnetic particle inspection
13&14 Degaussing,cleaning & check appearance
Finally Assembling
The above is all the process flow. We are also very serious about the later packing. We support packing and acceptance in the form of video or on-site visit. Welcome to visit!
