An international manufacturer of woodworking machines repeatedly encountered problems with the failure of guide rollers in their machines. NSK investigated the problem and found that the existing bearings had insufficient bearing tolerance combined with inconsistent bearing assembly methods resulting in the frequent failures. NSK proposed a higher tolerance support roller bearing combined with a training package that allowed consistant assembly of the table guide assembly. This enabled fault-free running of the machine and reduced fitting times for the bearings.
