Surface Treatment: Electrostatic Powder Coating, Galvanization.
Standard: DIN, CEMA, JIS, AS, SANS-SABS, GOST, AFNOR etc.

RAW MATERIAL OF ROLLERS:
1. Pipe:

High precision longitudinal seam-welded steel pipe, materials S235JR(EN 10025-2),St37-2 (DIN 17100)
Remove internal and external welding bars and uniform wall thickness ensure the roller good dynamic balance
Good out of roundness of pipe ensure the roller have small T.I.R
The pipe is cut and machined using automatic CNC machines, that guarantee the tolerances precision
Roller surface treatment is electrostatic powder coating, thickness of coating approx. 80-120 μ.

2. Shaft:
Cold-drawn round steel bar, materials S235JR(EN 10025-2),St37-2 (DIN 17100)
High precision diameter tolerance, seat IT6 acc. to EN ISO 286-1, perfect match with bearings.
Cut and machined by automatic numerically controlled machines
Precise positioning of circlip groove ensure roller have very small axial movement.
Galvanized shaft are available.

3. Bearing:
Deep-groove ball bearings, tolerance class P5 (DIN 620)
