Each pair of outboard and inboard roll stands, bearing bocks, and retainers are all fabricated of high strength castings. The inboard stands are machined with a keyway parallel with tube mill center centerline, while outboard stands are machined with a keyway perpendicular to tube mill centerline.
Top and bottom alloy steel hardened and ground roll shafts will be supported by one (1) inboard and one (1) outboard bearing block Assembly. Bearing block assemblies contain tapered roller bearings that are fitted and shimmed. Each bearing block assembly is supplied with grease fittings for lubrication. The outboard stand bearing block assemblies support and house a floating outboard inner race.
Top shaft bearing blocks are vertically adjustable and are equipped with single point adjustment with digital readout for accurate positioning of upper roll shafts.
Outboard roll stands are designed for quick tooling changeovers. By simply loosening two outboard stand mounting bolts, roll shaft retainer studs, and removing “C” washers, roll stands may be moved quickly to expose roll tooling.
