A major UK bakery was facing regular bearing failures on their Mecatherm Dough Mixer. Bearings needed to be replaced every 2 to 3 months resulting in high costs of maintenance and loss of production.
NSK reviewed the bearing application and recommended NSKHPS Spherical Roller Bearings. This improved bearing life significantly by 3 to 4 times and therefore reduced unplanned downtime resulting in a large cost saving.

Key Facts

  • 2 Mecatherm Dough Mixers in use
  • Dough Mixer application requires heavy load capacity together with bearings that can also accomodate swashing caused by shaft deflection
  • Original bearings only lasted between 2 & 3 months due to application conditions
  • NSK Solution: NSKHPS (High Performance Standard) Spherical Roller Bearings ideal for heavy loads
  • Bearing life extended by 3 to 4 times
  • Reduced maintenance requirement resulted in a significant cost saving generated
