In the integral design the journals are an integral part of the casting - a one-piece casting

Inserted and integral journals are being replaced by bolted-on journals as rolls are being replaced or journals repaired.

The inserted design consists of shrunk-fit steel journals utilized for small rolls.

Inserted and integral journals are being replaced by bolted-on journals as rolls are being replaced or journals repaired.

The bolted design consists of forged steel journals bolted to the chilled cast iron body. The body is counter-bored to accept a pintle from the journal. This fit takes the sheer load off the bolts.

The bolted design is a far superior design versus the inserted or integral designs.

In addition, steel forgings can be easily repaired, welded, or replaced.
