Manufacturing Process

Forging TestUnderstanding the material of the forging, the status after forging and check whether the forging has any default of lamination and surface cracks.

Turning After rough turning, ultrasonic forging examination to measure whether material inner parts any crack defects or slag inclusion, etc. and to make sure the bearings could reach normal service life and no premature failure.

Heat Treatment Medium frequency quenching on the surface of the bearing raceway, hardness not less than 55HRC, hardening case depth not less than 4mm, soft zone width not less than 50mm, mark in relevant.

Shaping and HobbingFor the slewing bearings with inner and outer teeth, shaping and hobbing process before grinding in accordance with the technical requirements procession grade requirement.

Drilling Mark and test accurately in CNC drilling machine according to technical requirement as drawing, make sure no dimension deviation before drilling. Installing holes combined with soft band 180 degree alternates and holes errors not larger than 0.5mm.

Grinding After rough grinding, resin grinding granularity wheel 46 or 60 degree applied. The finish grinding volume less than rough grinding volume. Finish degree and dimension meet the technology requirement in drawing.

Assembling Clearance preparation, trail assembly be carried out after grinding to get preliminary clearance, finial grinding is processed to reach required clearance in drawing. Then starting torque test, fix raceway, clean again to generate appropriate starting torque. Then component test, and final packing.

Design & Installation

Bearing installation diagram

Design & Installation Structure with the requirement shown in following figure:

Retaining screws secure the bearing components during transport. For installing the bearing easier, the screws should be loosened before fitting, and secured again or replaced by positioning screws-after fitting.

The L-section ring can be fitted with unsupported or supported ring.

u Without supported ring, the bearing type is YRT.

uWith supported ring, the bearing type is YRT...VSP, and the whole surface of L-section should be supported.

uMounting forces must only be applied to the bearing ring to be fitted, never through the rolling elements. Tighten the fixing screws in crosswise using a torque wrench(shown in figure 2)

uDon’t separate or interchanged bearing components during fitting and dismantling.

uStarting friction torque can be 3 to 3.5 times as high as the value of friction torque in the dimension tables.

YRT Rotary Table Bearing Installing:

Put the YRT bearing into bearing house

YRT bearing and bearing house is clearance fit
