Crossover Aluminum Guide Roller
1.do dynamic balance
2.wear-resistance and high quality
3.45# round steel
Outline:
Aluminum roller adopts the high quality of aluminum, and use advanced processing technology, the surface is using anodic oxidation treatment, we have two types of this product: HV300 (white) or HV700 (tawny), roll body surface smooth finish is 0.8 and 1.6, dynamic balance is within 2.0 g; Aluminum tube generally have 8-10 reinforcement. We can make slot roller according to
customers' requirement, such as: Crossover aluminum roller, horizontal center, aluminum roller, roller, and cooling roller.
