Introduction
A large pet food manufacturer in the UK was experiencing problems on their pellet extruder machine. They experienced bearing failures and loss of production every 10 to 12 weeks. The customer asked NSK to review the application. After the analysis it was determined the existing grease lubrication would not fulfill the bearing life expectancy. NSK recommended a high viscosity oil for a longer life and proposed a solution to extend the bearing life. The customer replaced the existing bearing with high quality NSK Spherical Roller Bearings (EA series) and Spherical Thrust Roller Bearings. The extruder was reassembled and run for 7 months without any failures.
- Extruder Machine - Pet Food Manufacturer
- Spherical Roller Bearings - EA Series
Key Facts
- The extruder machine of a pet food manufacturer suffered from bearing failures every 10 to 12 weeks
- NSK examined the application and found high axial loads which led to frequent failures
- This resulted in high downtime and a loss of production
- NSK recommended to change the lubricant to a high viscosity oil and propsed to change to NSKHPS Spherical Roller Bearings (EA series)
- After these recommendations the extruder was running for 7 months without any problems
