Welcome to Linqing Xinshengdi Bearing Co., Ltd.
30228 Tapered Roller Bearing
- Dimensions: 140mm (d) x 250mm (D) x 45.75mm (T)
- Thermal-stabilized cage architecture prevents high-temp binding.
- Distributes extreme line-contact forces across massive kiln tires.
- Designed for low-speed, high-pressure continuous processing.
Operating 24/7 at elevated temperatures, cement rotary kilns represent one of the most punishing environments in heavy manufacturing. The 140mm bore 30228 bearing supports the enormous dead weight of the rotating kiln drum. Undergoing advanced thermal stabilization, the bearing elements resist expanding or seizing under intense radiant heat, ensuring balanced weight distribution across the supporting rollers and preventing uneven kiln tire wear.
