What kind of bearings are used in pellet machines? Analysis of hot topics across the Internet

Recently, the topic of bearing selection for pellet mills has triggered widespread discussions in the field of industrial manufacturing. With the advancement of environmental protection policies and the growth of biomass energy demand, the durability and performance of the bearings of pellet mills as core equipment have become the focus of users. This article will combine the hot data of the entire network in the past 10 days to provide you with a detailed analysis of the selection points of pellet machine bearings and provide structured data reference.

1. Core requirements for pellet machine bearings

Pellet machines are usually used to suppress biomass materials such as wood chips and straw. The working environment is characterized by high load, high dust and high temperature, so the bearings must meet the following conditions:

• High load carrying capacity: Bear the combined radial and axial pressure;
• Sealing: Prevent dust intrusion from causing lubrication failure;
• High temperature resistance: Adapt to the heat generated by continuous operation.

2. Comparison of mainstream bearing types

According to data from industry forums and e-commerce platforms, the following is a performance comparison of commonly used bearing types for pellet machines:

3. Popular brands and user feedback

E-commerce platform data in the past 10 days shows that the search volume for bearings of the following brands has increased significantly:

User feedback hot spots:The sealing design of SKF bearings performs well in dusty environments, while NSK's cost-effectiveness is more favored by small and medium-sized enterprises.

4. Suggestions on model selection and maintenance points

Combined with expert opinions, attention should be paid to the following when selecting bearings for pellet mills:

1. Matching load:Select bearing size and type according to equipment power;
2. Lubrication solution: It is recommended to use high-temperature lithium-based grease and replenish it regularly;
3. Installation accuracy: Axial clearance is controlled at 0.1-0.15mm.

In addition, the recently hotly discussed topic of "bearing preload adjustment" in industry forums shows thatExcessive preload force will shorten the bearing life by more than 30%, need to operate strictly according to the manual.

5. Future Trend: Intelligent Bearing Monitoring

With the popularization of Internet of Things technology, smart bearings with sensors have become a new hot spot. This type of bearing can monitor temperature and vibration data in real time and provide early warning of faults. It is especially suitable for continuous production pellet machine scenarios.

Summary: The selection of bearings for pellet mills needs to take into account equipment operating conditions, cost and maintenance convenience. Priority should be given to spherical roller or tapered roller bearings, and attention should be paid to sealing performance. Regular lubrication and condition monitoring are key to extending life.
