Kiln Support Rollers are backed by latest technology and provide desired support to cables and other related products. These support rollers are driven to rotate using friction between roller surface and web. The small friction torque of the roller bearings also allow higher speed operations and helps in avoiding possibilities of slippage due to presence of large air film between roller surface and web.
The rotary kiln Support roller is mainly used in rotary kiln / dryer / cooler and rotation device, usually there are two sets or three sets support roller in one rotary kiln, there will be a set support roller with thrust roller when three sets support roller
be used.
The support roller bear all weight of device, so it made by quality cast steel, and rolling through a axis in the center of support roller.
Features :
- High-precision dimensional tolerance; Excellent mechanical properties; Produce different dimension based on customer’s requirements; Advanced manufacture equipments and inspection devices; Excellent technical personality; Control the production procedure strictly; Pay attention on the package protection.

Advantages of Heat Treatment for the Trunnion Roller
1. Professional, Specific Electrical Furnace, single-minded
2. Vertical Pit Furnace, keep the temperature uniformity during heating, +/-1℃
3. Small deformation, little oxide layer, reduce the material cost
4. Difference materials can be cold at the best speed.
5. Large capacity, completed variety of quenching medium: oil, water, salt water, water based mixture.
