Roller bearings are an important component of the support system in conveyor belts. In order to enable conveyor belt rollers to operate under extreme conditions, NKE Austria has developed special single-row deep groove ball bearings. Compared with standard bearings, this bearing has optimized performance and longer service life, reducing downtime of the entire conveyor system.

The main purpose of the support and tension rollers in the conveyor belt is to shape the conveyor belt, serve as a support element for the material to be conveyed, and reduce the resistance to movement. When the material is transported with minimum friction, the total energy required for transportation is reduced, This also reduces operating costs. In an open pit mining environment, conveyor belt pulleys are exposed to harsh operating conditions and environments, including heavy loads, vibration and shaft deflection stresses, high rotational speeds, increased loads due to external contamination, and high humidity, rain. Snow and other harsh weather conditions.

After extensive analysis, NKE has developed single-row deep groove ball bearings, particularly suitable for conveyor belt pulleys operating in harsh conditions, which feature targeted improvements compared to standard bearings to optimize performance and service life. , these bearings feature a special cage structure made of low-friction synthetic material, improved raceway geometry, adjusted radial internal clearance, special low-friction seals and selected lubricants to operate over a wide operating temperature range For internal use.

When contaminants seep inside the bearing, the temperature of a standard bearing often rises suddenly and uncontrollably. The increased temperature can weaken the grease, damage the steel cage, and eventually cause the bearing to seize. When the bearing seizes, it blocks the drum, causing Damaged conveyor belts significantly increase the risk of fire.

To this end, NKE has designed new ball bearings that maintain their functionality even under heavy loads and without increased frictional torque, reducing the risk of fire, extending the service life of roller bearings in the harshest conditions, and reducing energy consumption, improves conveyor system reliability and reduces overall operating costs.

"We have extensive expertise in mining applications," said Mi Gong, application engineer at NKE. "This is an extremely complex engineering achievement to meet the needs of many customers for improved conveyor belt performance and reliability. Our new roller The sub-bearing system will help significantly reduce downtime of material handling equipment."
