Application: Mecatherm Dough Mixer
Cost Savings: $51,236
Introduction
A major UK bakery was experiencing regular bearing failures on their Mecatherm Dough Mixer. Bearings needed to be replaced every 2 to 3 months resulting in high maintenance cost 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.
- Dough Mixer
- NSKHPS Spherical Roller Bearings
Key Facts
- 2 Mecatherm Dough Mixers in use
- Dough Mixer application requires heavy load capacity together with bearings that can 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 requirements resulting in a significant cost savings
Value Proposals
- NSK Engineers reviewed bearing application including an analysis of the failed bearings
- Recommended NSKHPS Spherical Roller Bearings
- A trial of NSKHPS bearings resulted in increased bearing life by 3 to 4 times
