1Completely Customizable
If your application calls for custom shaped wire, we can machine custom shaped grooves to match your specifications, even for small orders.
2Sjogren Alignment Marker
Exclusive to Sjogren Industries' rollers, the alignment marker ensures precise maintenance of the wire’s centerline from one roller to the next. While most grooved roll machining overlooks variations in bearing width, Sjogren employs precision measurement to pinpoint the exact groove position.
This alignment marker effectively addresses bearing width variations, simplifying the process for operators to correctly mount replacement rollers and uphold tolerances.
3Specialty Rollers
Working with precious metals, coated wire, or special shape wire and cable? We can help!
From custom u-grooves, square, star, cotter pin shapes, we have the precision to match your needs. We can also manufacture non-metallic straightener roll surfaces.
We design to fit your production.
4Compatibility
Our grooved straightener rolls are compatible with any manufacturer’s assembly. Need replacements for a straightener we didn't make? Send us photos, specs, or a sample, and we will design for you.
5High-Speed Options
Sjogren's exclusive high-speed roller design enhances spindle uptime by facilitating increased line speeds and reducing the need for frequent replacements.
The High Speed Cartridge Assembly is adaptable to various straighteners and accommodates different roller sizes or groove shapes. This assembly features two pre-loaded bearings, ensuring exceptional straightener performance even at elevated line speeds.
These reduce roller wobble at high speed, which improves straightener performance.
The cartridge design stops over-tightening during replacement, removing a common mistake often made by less experienced operators.

Grooved Roll FAQ
What is the difference that the alignment marker makes?
THE DIFFERENCE THAT SJOGREN’S ALIGNMENT MARKER MAKES:
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. The Sjogren alignment marker accounts for variations in bearing width and makes it easy for the operator to identify the correct way to mount replacement rollers to maintain tolerances.
The benefits include;
- Reduction in set-up time
- Vastly improves centerline alignment
- Improved productivity increases profits
How do you place the grooved roll with the orientation marker?
Review the following image for visual representation. you want the marker groove closest to the straightener base.
How do you set your grooved rolls on a straightener to eliminate curves?
Once you have mounted your rolls, you will adjust each knob slightly to slightly push the wire or rod down, and up respectively. Review the image below for a visual representation. the goal is to push just enough until the output is straight. This may take 2 or more planes, depending on your product.
What is the recommended maintenance schedule for grooved rolls?
The maintenance of your rolls is significantly influenced by their usage frequency, the surrounding environment, and the type of product being straightened. Below is a recommended maintenance schedule for vee and radius grooves, tailored for low, medium, high-carbon, and non-ferrous materials, based on 80-100 hours of machine operation.
| Groove Type | Material | Replacement Frequency |
| VEE | Low Carbon | 9 months |
| VEE | Medium Carbon |
6 months |
| VEE | High Carbon | 3 months |
| VEE | Nonferrous | 12-18 months |
| Radius | Low Carbon | 12 months |
| Radius | Medium Carbon | 9 months |
| Radius | High Carbon | 6 months |
| Radius | Nonferrous | 15-21 months |
