Grooved Rolls
ROLLERS FOR ANY STRAIGHTENER
No matter what manufacturer’s straightener assembly you currently use, Sjogren can provide you with replacement grooved rolls that will work in your current configuration. Any size roller, any shape groove, any quantity — including short runs.
CUSTOM GROOVE SHAPES
If your drawing process requires a non-standard wire shape, Sjogren can suit your exact specifications. Our machining tolerances assure you of an exact match. If you have been told that your custom groove request cannot be met because the order is too small or too unusual, we are ready to help you.
SJOGREN’S ALIGNMENT MARKER
A feature found only on Sjogren rollers, the alignment marker assures the operator that the wire’s centerline is maintained exactly from one roller to the next. Most grooved roll machining fails to account for variations in bearing width; Sjogren uses precision measurement to identify the exact groove position.
HIGH SPEED CARTRIDGE ASSEMBLY
A new roller design exclusively from Sjogren, it improves spindle uptime by enabling faster line speeds and less frequent replacement. The High Speed Cartridge Assembly is compatible with any straightener and any roller size or groove shape. The assembly incorporates two pre-loaded bearings for superior straightener performance at high line speeds.

SHORT RUNS / RADIUS GROOVE
A radius groove roll is more precise and creates fewer wear/marking problems than the more common V-groove rolls. Because Sjogren accommodates custom orders even in very small quantities, we are able to supply customers with specific diameter radius grooved rolls when other suppliers cannot.
SPECIALTY MATERIALS
Operations involving specially coated wire or soft/precious metals often require a non-metallic straightener roll surface. Sjogren can help you find solutions to marking problems by supplying you with the appropriate non-metal rollers.
SJOGREN’S HEAT TREAT & COATING PROCESS
This innovation, available only from Sjogren, addresses problems associated with high line speed operations. High line speeds typically require expensive specialty roller materials to avoid groove wear, or else suffer excessive downtime due to frequent replacement of conventional rollers. Sjogren’s process delivers performance approaching that of carbide at significantly lower cost.
