Slide Core Unit for Core Pin Mounting

Product catalog summary

Guide Rail Specifications and Tolerances

The document provides detailed dimensional specifications and tolerances for guide rails used in slide core units. Key dimensions such as widths, diameters, and hole sizes are specified with tight tolerances, typically ±0.02 mm for critical features. Tolerances for dowel holes and knock holes are explicitly noted, ensuring precise alignment and fit.

Dimensions include various diameters (e.g., φ8H7, φ9, φ14, φ20, φ22) and hole placements with tolerances ranging from +0.05 to -0.05 mm depending on the feature. Angular measurements such as 15° and 17° are also specified for certain components.

Slide Core Unit (SCUC and SCUB) Details

The slide core units are designed for core pin mounting and come in two types: SCUC and SCUB. The catalog numbers follow the format W-D-T-U, with increments of 0.1 mm for dimensions. SCUB type requires only the W dimension indication.

Material options for the slide core are flexible, with a recommendation to contact the sales department for changes. The guide rail referenced is SGLWN25-100, with further details available on page 131 of the original catalog. Locking blocks and angular pins are detailed on page 125.

Spring and Stopper Specifications

The coil spring used (TF20-45) has a free length of 45 mm, an initial load of 14.3 kgf, and a final load of 28.6 kgf, with a spring constant of 1.43 kgf/mm. The stopper (STB) is made of S45C steel and is an accessory part.

Special attention is advised when installing parts at the end of the slide core to consider load impacts carefully.
