UKL Crossed Roller Bearings
，
with the cross roller bearing ,cylindrical roller are arranged crosswise ,
with each roller perpendicular to the adjacent roller,in a 90°groove ,separated from each other by a spacer retainer
.This design allows just one bearing to receive loads in all directions including ,radial,axial,and moment loads.
Since the cross-roller ring achieves high rigidity and the
precision can reach up P5 P4 P2
,despite the minimum possible dimensions of the inner and outer rings.
It is optimal for applications such as joints and swiveling units of industrial robots,swiveling table of machining centers .
precision rotary tables,medical equipment,measuring instruments and IC manufacturing machines.
Cross Roller Bearing Series
RU/XSU/XU CROSS ROLLER BEARING SERIES FEATURE:
Since the mounting holes are provided, this model does not require a presser flange or housing .In addition because it has an integrated inner/outer ring structure and is equipped with washers ,its performance is minimally affected by the mounting procedure,ensuring stable rotation accuracy and torque.This model can be used for both inner-ring rotation and outer-ring rotation.
Product Process
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.
Drilling
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
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.
Title goes here.
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%.
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.
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.
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.
