35° Grooved Roller Assembly
Product Details
Materials and Components
The roller body tubes are made from ERW (Electric Resistance Welded) high-frequency welded tubes, whilst the roller shafts are cold-drawn; both the tubing and shafts are manufactured from materials specifically designed for conveyor idler rollers.
Shaft diameter tolerances are strictly controlled within -0.01 mm to +0.01 mm to ensure precise bearing assembly.
Cut-to-length
Fully automatic tube and shaft cutting equipment is utilised to ensure consistent length dimensions for all tubular and shaft components.
Anti-corrosion Coating of Pipe Inner Walls
The inner walls of all idler roller pipes are treated with an anti-corrosion coating to prevent rusting and effectively extend the service life of the idler rollers.
End Face Milling of Shafts
After the shafts have been cut, specialised end-face machining equipment is used to perform precision milling on both ends of the shafts.
Tube Boring
Precision boring is performed at both ends of the tube using double-end boring equipment, ensuring the coaxiality accuracy of the bearing seats.
Flat Position Milling on Shafts
The critical dimension for roller installation is the flat position spacing; a four-cutter synchronous milling process is employed to ensure that the dimensions of all flat positions on the shafts are completely consistent.
Bearing Housing Welding
An integrated welding process is applied to both ends to ensure coaxiality, concentricity and centreline alignment of the bearing housings on both sides.
Precision Turning of the Roller Shaft
CNC lathes are used to machine the seal grooves, resulting in high precision and a smooth, polished surface.
Bearing and Seal Assembly
Bearings and seals are precision-fitted to the roller assembly.
Once assembly is complete, the unit proceeds to quality inspection and the overall painting process.
