This concrete pipe cutter (pictured above) presented several problems before it was fitted with CHTK® R linear bearings.

Before the new linear bearings were used, the old recirculating ball bearings of the pipe cutter would easily accumulate dirt. The dirt would cause the balls to jam and this would regularly ruin the hard-chromed shafts of the pipe cutter.

With the addition of CHTK® R (RJUM-01) linear bearings, the machine has now run problem free for over three years.
