PROEXPORT / INDUSTRIAL ROLLERS
Custom Fabricated Industrial Rollers & Cores | PROEXPORT
PROEXPORT provides complete end-to-end manufacturing of new industrial rollers and precision shafts based on engineering drawings or physical samples. From structural carbon steel and stainless steel to lightweight aluminum alloys, we manufacture single-shell and double-shell rolls with tight geometric tolerances and certified dynamic balancing.
TECHNICAL SPECIFICATIONS
Manufacturing Parameters and Operating Tolerances
We match core construction, elastomer compound or metallic coating, and surface finish directly to the operating conditions on your line.
| Technical Parameter | Specification / PROEXPORT Standard |
|---|---|
| Core Materials | Carbon steel (S355, C45, 42CrMo4), Stainless (1.4301, 1.4404), Aluminum (EN AW-6082) |
| Internal Structure | Hollow tube, heavy-wall pipe, solid forged bar, or double-shell spiral jacket |
| Bearing Journals | Precision CNC turned, induction hardened, and ground to ISO k5/m5 fits |
| Manufacturing Limits | Diameter from Ø50 mm to Ø1600 mm, total length up to 6500 mm |
| Balancing Standard | Dynamic balancing ISO 1940 G1.0 or G2.5 for operating speeds up to 2000 m/min |
| Coating Integration | Delivered ready for production with rubber, PU, silicone, chrome or ceramic covering |
LINE PROBLEM SOLVING (PWE)
Precision that Eliminates Line Downtime and Web Defects
At PROEXPORT, we do not simply supply coatings — we solve specific engineering challenges for plant technologists and maintenance leaders.
PRODUCTION CHALLENGE
Line Issue
Excessive shaft deflection and resonance vibration at elevated production speeds causing uneven web processing.
PROEXPORT SOLUTION
Engineering Solution
FEA-calculated core geometry with internal stiffening ribs, precision concentric welding, and dynamic multi-plane balancing.
PLANT ROI RESULT
Measurable Effect
Zero shaft deflection under nip load, vibration-free high-speed performance, and drop-in compatibility with OEM machine frames.
SELECTION & QUALITY CONTROL
Pre-Production Specification & Quality Inspection
Every project — new fabrication or reconditioning — is executed according to strictly defined inspection points:
- Ultrasonic testing of raw steel bars and welded seams.
- Coordinate measuring machine (CMM) and micrometer verification of bearing journals.
- Full dynamic balancing certificate with residual unbalance protocol.
- Material test certificates according to EN 10204 3.1.
Technical Acceptance Standards
| Inspection Dimension | Technical Significance |
|---|---|
| Geometry & Tolerances | Diameter calibration, radial/axial runout, and concentricity of bearing journals. |
| Coating Structure | Durometer Shore/HV verification, nominal thickness, and zero-porosity bonding. |
| Dynamic Balancing | Residual unbalance compensation in ISO 1940 Grade G 2.5 or G 6.3. |
FREQUENTLY ASKED QUESTIONS (FAQ)
Frequently Asked Questions (FAQ)
What information is required to order a new custom roller?
Provide an engineering drawing specifying dimensions, tolerances, bearing fits, operating speed, linear load, and surface requirements. If no drawing exists, we can reverse-engineer from your sample.
Can PROEXPORT produce internal heating or cooling rollers?
Yes. We manufacture double-jacketed rollers with internal spiral displacement channels designed for uniform heat distribution with steam, oil, or chilled water.
