Products Description




china OEM manufacturer Aerospace series Nylon retainer YRT150rotary table bearing
YRT rotary table bearings are axial and radial combined cylindrical roller bearings, which are fixed by a bidirectional thrust bearing and a centripetal-guided bearing.
They can support radial loads, axial loads from both directions and tilting moments free from clearance.
For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to
prevent rollers and rings generating collisions which influence bearing accuracy.

Product Process




  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.



According to the drawings, the machining center is required to process. The key point is to level the countersink not to be uneven; the through hole be smooth without spirals; the threaded hole meets the requirements, can not drill bottom hole too large for easy & fast tapping. Hole chamfer requires angle, size and appearance all meet the requirements.



  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.



  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%.



  Ensure chamfer, oil groove smooth and without vibration.





     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.





  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.





Magnetic Particle Inspection: fully magnetizing to make the magnetic powder evenly poured on the product. Observing whether the magnetic powder is concentrated. There would be no concentrated or remaining magnetic powder for good products.
