Technical Features and Specifications
Support rollers must maintain a perfectly cylindrical profile under multi-ton loads.
| Feature | Detail |
|---|---|
| Material Grades | 42CrMo4, 34CrNiMo6 (High hardenability alloys). |
| Forging Method | Open-die forging for large diameters. |
| Heat Treatment | Through-hardening or surface induction hardening. |
Our rollers are forged with a specific emphasis on the "Hertzian Contact Stress" zones. By refining the grain structure, we ensure the metal can flex slightly under the roller's load without developing surface micro-cracks. The shafts and rollers are often integrally forged or shrink-fitted with extreme precision to ensure zero slippage.

Buying Tips for Plant Operators
- Alignment Tolerance: Ensure the roller is machined to ultra-tight runout tolerances; even a small "wobble" will lead to rapid kiln tyre wear.
- Lubrication Paths: For rollers with integrated bearings, ensure the forging allows for clean, unobstructed grease paths.
- Thermal Resistance: If used on a hot kiln, specify an alloy that maintains its hardness at elevated operating temperatures.
Advantages of Forged Rollers
| Advantage | Operational Benefit |
|---|---|
| High Contact Strength | Prevents "grooving" or flattening of the roller surface. |
| Longevity | Extended intervals between expensive kiln realignments. |
| Safety | Eliminates the risk of sudden roller failure which can tilt the kiln. |
Primary Applications
| Industry | Usage Context |
|---|---|
| Cement & Lime | Supporting rotary kilns and large material dryers. |
| Mining | Trunnion rollers for SAG and ball mills. |
| Sugar Processing | Large crushing mill rollers and diffusers. |
- Q: Why are forged rollers better than cast ones?
- A: Cast rollers often have "centerline porosity." Under the intense pressure of a kiln, these internal voids can collapse, leading to rapid surface failure and uneven wear.
