Introduction
A textile manufacturing company had experienced repetitive failures at approximately 6 months in air circulation motor-fans used on their fabric furnace. During an onsite inspection, NSK found out a relatively high operating temperature in the furnace. Taking this into account, NSK proposed an alternative Deep Groove Ball Bearing type, designed specifically for the use in applications with higher temperatures. A trial was initiated which demonstrated that the bearing life was extended twice compared to standard products. This resulted in a significant reduction in maintenance costs, no unplanned breakdowns and a subsequent improvement in productivity.
- Textile Manufacturing
- Deep Groove Ball Bearing with high temperature seal
Key Facts
- Special textile manufacturing plant
- Fabric furnace motor-fan
- Repetitive failures experienced between planned maintenance shut downs
- Bearing failing due to high operating temperatures
- NSK Solution: NSK proposed an alternative Deep Groove Ball Bearing for high temperature applications
- A trial showed that the bearings lasted more than twice than standard units
- No unplanned failures in a 12 month period
- Consequently a cost saving was realised due to reduced maintenance and no lost production
- Textile Manufacturing Deep Groove Ball Bearing with high temperature seal
Value Proposals
- The customer explained they were having repetitive bearing failures in their furnace motor-fan
- An NSK application revie identified the cause was the high temperatures generated in the furnace
- The customer mentioned they were using standard Deep Groove Ball Bearings in the motor-fans
- NSK proposed a trial using high temperature Deep Groove Ball Bearings
- The trial was successful with no bearing problems in over a year
- This resulted in a significant cost saving due to reduced maintenance and no lost production
