NC Series
Baier
Overview & Features
Baier NC Series hydraulic nut splitters are designed to split hex nuts for removal during industrial maintenance. Seven models cover nut widths across flats from 10 to 75 mm, with cylinder outputs from 5 to 90 ton. Each model has its own capacity and dimensions. Select according to nut size, material and working clearance. An external hydraulic hand pump is required.
10–75 mm Nut AF | 7 Models | 5–90 ton Cylinder Output
Seven Model Options: Nut AF ranges from 10 to 75 mm across the series.
5–90 ton Cylinder Output: Select the capacity required for your application.
Compact Angled Head: Check head dimensions against the available working clearance.
Single-Acting Spring Return: Hydraulic advance with spring return after pressure release.
Regrindable Chisel: Supports chisel maintenance according to the tool’s servicing instructions.
The NC-1924 shown in the component photographs is a representative model. Refer to the specification table for each model’s capacity and dimensions.
The angled cutting head positions the chisel against the nut for splitting. Check the nut width across flats, nut height and surrounding clearance before selecting a model. Follow the applicable maintenance instructions when regrinding the chisel to retain the correct cutting geometry.
Hydraulic pressure advances the chisel. The single-acting cylinder uses spring return after pressure is released. Match the pump, hose and coupler to the selected tool, including the connection type, operating pressure and oil requirement. Confirm the supplied coupler configuration when ordering.
Technical Specifications
Compare nut AF range, cylinder output, oil capacity and tool weight to identify a suitable model.
Model | Nut AF Range (mm) | Cylinder Output (ton) | Oil Capacity (cm³) | Weight (kg) |
|---|---|---|---|---|
NC-1019 | 10–19 | 5 | 15 | 1.2 |
NC-1924 | 19–24 | 10 | 20 | 2 |
NC-2432 | 24–32 | 15 | 60 | 3 |
NC-3241 | 32–41 | 20 | 80 | 4.4 |
NC-4150 | 41–50 | 35 | 155 | 8.2 |
NC-5060 | 50–60 | 50 | 240 | 11.8 |
NC-6075 | 60–75 | 90 | 492 | 34.1 |
AF means width across flats of the hex nut, not bolt diameter. Final selection also depends on nut material, hardness and working clearance.

All dimensions are in millimetres. Request the complete model drawing for dimension reference positions before checking fit. For restricted access, send a photo or drawing showing the nut and surrounding components.
System & Applications
An external hydraulic hand pump is required. Select the pump, hose and coupler as a compatible system for the chosen model. Tell us whether you need the tool only or a quotation including hydraulic accessories. Package contents will be specified in the quotation.
Confirm the nut: Provide the nut AF size, height and material or grade.
Check access: Share available clearance and an application photo.
Match the system: Provide existing pump details or request a matched system quotation.
System photographs are configuration illustrations. Confirm compatibility for the selected model.
NC Series hydraulic nut splitters can be considered for maintenance tasks involving nuts that are difficult to remove by conventional loosening. Select the tool according to actual fastener condition, material and site access.
Application | Typical Task |
|---|---|
Pipeline Maintenance | Nut removal during planned maintenance of pipeline and flange assemblies. |
Steel Structures | Maintenance of accessible bolted connections where nut splitting is appropriate. |
Mining Equipment | Nut removal during servicing of mining and processing equipment. |
Cement Plants | Maintenance of bolted assemblies on plant equipment and supporting structures. |
Send your nut dimensions, material or grade, quantity and application photo. For distributor or multi-model purchasing, include your required model mix and destination country.
FAQ
The series covers hex nut widths across flats from 10 to 75 mm across seven models. Each model has its own specified range.
No. AF is the distance between two opposite flat faces of the hex nut. Measure the nut directly rather than selecting only by bolt diameter.
Yes. An external hydraulic hand pump is required. Confirm pump, hose and coupler compatibility with the selected model.
Provide the nut AF size, height, material or grade, and available clearance. An application photo helps with selection.
Suitability depends on nut material, hardness, dimensions and tool capacity. Confirm these details before selecting a model.
Yes. The NC Series uses a regrindable chisel. Follow the applicable servicing instructions for the correct cutting geometry.
Package contents depend on the quoted configuration. Specify whether you require the tool only or hydraulic accessories as well.
Yes. Include required models, quantities and destination country. For distributor inquiries, include your company and target market.
