140mm 5.51 inch outer diameter low intertia carbon fiber shaft for guide roller
The carbon fiber shaft is mainly used by UD(unidirectional carbon fiber) with a layer 3K twill carbon fiber outside, The majority of our unidirectional carbon tubes are comprised of 0° and 90° degree plies with an occasional layup deploying 45° plies/30° plies. most all of our roll-wrapped carbon tubes have underlying layers of unidirectional carbon fiber.
| Name | Roundness /Straightness | Outer diameter(OD) tolerance |
| 140mm Outer diameter carbon fiber shaft for guide roller | 0.1mm /0.1mm | tolerance +/0.10mm |
Carbn fiber shaft for guide roller have advantage as follows:
•1. Carbon fiber roller is light weight, It density 1.6g/cm3, Steel density 7.8g/cm3, Aluminum density:2.7g/cm3;
•2. High strength, Carbon fiber roller tensile strength 4900Mpa, Steel 780-1200Mpa, Aluminum 700-1200 Mpa; Carbon fiber strength at least 4 times than steel;
•3. Carbon fiber roller rigidity is better than Steel and Aluminum, Carbon fiber elasticity Modulus is 240Gpa, steel 110Gpa, So carbon fiber roller is not easy transform than Steel and other metal;
•4.Carbon fiber rollers have small inertia, fast start-up and deceleration. They are suitable for speed control, especially for high-speed equipment.
•5.Carbon fiber roller is light weight, So it have Low resistance, It can make equipment speed can increase 50% , So that can improving Production Speed of Production Line, Then Increasing Production and Reducing Energy Consumption and cost.
•6.Carbon fiber roller can working at the temperature -50~+120 ℃ with long time. It is not easy to transform, Long service cycle.
