Plain Guide Rails No Groove

Plain guide rails without a groove are used in injection mold tooling and automation fixtures where stable linear sliding is required but an internal lubrication channel is undesirable. They are especially common in slide mechanisms for undercut release systems, where consistent rail-to-cam motion helps maintain alignment through repeated cycles.

For automotive connector and housing molds, the no-groove variant supports oil-free or externally lubricated layouts, reducing contamination risk in optics and electrical-contact areas. The selectable oil groove version can be used when centralized lubrication is already designed into the slide pack.

In medical device packaging tooling and clean assembly jigs, the simplified groove/non-groove selection helps match maintenance practices while keeping sliding friction predictable. Rail thickness and width compatibility (T 10–30 mm, W 10–40 mm) enables tuning the slide stiffness and load path.

• Choose SKS3 or HPM2T depending on tool steel and wear/toughness priorities
• Select oil groove option to fit lubrication architecture
• Use the available mounting hole counts (2/3/4) and pitch ranges for secure slide plate integration

This guide rail is offered in SKS3 or HPM2T tool steel, allowing you to match performance to your slide duty cycle and wear environment. However, the provided specification data does not define the exact hardness (HRC) or heat-treatment state for each grade, so you should confirm the supplier’s material condition for your specific SKU.

• SKS3: typically selected for balanced machining and service performance in moderate wear applications.
• HPM2T: typically selected when higher wear resistance and improved sliding durability are prioritized for repetitive motion.

Manufacturing for these rails generally involves bar/plate steel preparation, precision milling/finishing of the sliding faces, and drilling of the mounting holes to match the defined pitches (A 6–10.5 mm, B 16–31.5 mm, C 26–52.5 mm; D up to the listed ranges). If your project requires lower friction or improved surface durability, consider additional surface finishing or case treatments as specified by your engineering standards.

Selection starts by matching the rail’s thickness (T), width (W), and length (L) to the slide guide plate geometry and load distribution. Use T in the range 10–30 mm and W in the range 10–40 mm. For length, choose from the available L ranges: 35–100, 40–150, 40–200, 50–200, 120–200, or 40–100.

Next, match the mounting pattern to your slide plate by selecting the number of holes (2, 3, or 4) and the bolt-hole pitches: A 6–10.5 mm, B 16–31.5 mm, C 26–52.5 mm, and D across the listed ranges (e.g., 36–94, 41.5–143, up to 73.5–189.5 depending on configuration).

• Confirm your core/cavity tooling clearances so the rail thickness and width do not interfere with slide cams.
• Because tolerance values are not provided in the data, verify fit and alignment requirements using your internal rail-to-cam and fastening standards before final drawing release.
