Entry Guide System
Roller and channel-type entry guides that present the stock squarely to the pass, machined, fitted and set in house as complete assemblies.
Discuss Your RequirementSpecified around the line—not selected from a generic list.
The entry guide decides what the pass actually sees. Roller spacing, entry bell geometry, bearing arrangement and the repeatability of the mounting determine how the section tracks, how the surface finishes and how quickly a set can be changed. NSG EA builds entry guides as complete assemblies—body, rollers, bushings, entry bell and adjusting hardware—so the fit at the stand is verified before dispatch.
Engineering scope
- Roller entry guides with conical and rectangular entry bells
- Static and channel-type guide bodies
- Spring-loaded and screw-adjusted roller arrangements
- Hardened guide rolls, bushings and wear sleeves
- Reverse engineering from installed or worn samples
- Matched sets machined to a common mounting datum
Typical applications
- 01Roughing, intermediate and finishing stands
- 02Entry positions across the pass line
- 03Section and structural rolling mills
- 04Changeover spares and shutdown replacements
What an entry guide does
The entry guide sits in front of the roll pass. It catches the stock coming from the previous stand, holds it on the pass centreline and keeps it in the right orientation as it enters the rolls—an oval entering a round pass, for example, has to stay upright or the bar will twist and the section will go out of tolerance.
Roller guides hold the stock between free-running rollers, which reduces friction and surface scratching compared with sliding contact. Static guides hold the stock in a machined channel and are used where the stock is larger, slower or a shape that does not need roller support.
What makes an entry guide run well
The roller gap has to be set to the incoming section and held there, so the adjusting hardware must lock firmly. The rollers must spin freely: a seized roller marks every bar that passes. Water cooling keeps the rollers and bearings within their working temperature, and the entry bell is shaped to catch the front end of the bar cleanly.
Alignment to the pass centreline depends on the guide mounting. Guides made to a common datum can be pre-set off the mill and swapped in quickly, which shortens changeovers.
Built as complete assemblies
NSG EA builds entry guides complete—body, rollers, bushings, entry bell and adjusting hardware—and fits them together before dispatch. Where there is no drawing, a guide can be reverse engineered from an installed or worn unit, and the matching rollers and bushings can then be ordered as spares.

Questions buyers ask early
Can entry guides be made to match an existing stand?
Yes. Working from an installed sample, a worn unit or measured mounting data, guides can be produced to the existing datum so they drop into the current stand without rework.
Are rollers and bushings supplied with the guide?
Entry guides are supplied as complete assemblies including rollers, bushings and adjusting hardware, and the same wear parts can be ordered separately as spares.
Can a matched set be supplied for a full line?
Sets are machined to a common mounting datum so units are interchangeable across positions, which keeps changeover predictable across the line.
Should a stand use a roller guide or a static guide?
Roller guides suit positions where the stock must be held accurately at speed, such as an oval entering a round pass in the intermediate and finishing stands. Static guides are simpler and suit roughing positions and slower, heavier stock. The pass design decides which is right for each stand.
