Plain Guide Short Sleeves Press Fit Style Inch Bushing

Plain guide short sleeves are commonly used in injection mold and die-set tooling where components must stay aligned through repetitive cycles. This press-fit style sleeve is well suited for die-set alignment systems in industrial forming or molding setups that rely on rigid, non-adjustable positioning.

In practical builds, the sleeve is installed on the leader or guide posts using a press-fit assembly to create stable guidance during opening/closing, helping reduce variation across long runs. The plain (non-rolling) guide surface supports consistent sliding motion when you want predictable behavior without the complexity of more specialized bearings.

• Automotive and industrial forming: use for die-set guidance where repeatability and post retention are priorities.
• High-cycle production housings/frames: ideal when a simple, robust guide bush supports smooth, aligned motion.
• Press-fit guide modules: selected when inch post diameter A and length L must be matched to your existing guide system.

This variant is specified as a steel plain guide bushing intended for rigid, press-fit retention in guide applications. The product data does not list a specific alloy grade, so material selection should be confirmed against your supplier documentation before final heat-treatment requirements are finalized.

For press-fit bushings in mold/die guidance, steel is typically chosen for its balance of wear resistance (sliding contact durability) and toughness (resistance to cracking under assembly stress and cyclic loading). Depending on the in-house spec, steel sleeves may be used in a pre-hardened condition or quenched and tempered to reach target hardness for guidance service.

• Hardness & trade-offs: higher hardness improves wear resistance but can reduce impact toughness if excessively tempered.
• Heat-treatment confirmation: verify whether the sleeve is supplied as-cast/normalized, pre-hardened, or heat-treated for the intended contact pressures.

To select the correct sleeve, match your guide post geometry to the sleeve’s inch ranges. The key variable is the post diameter A (in), which must be within 1 ~ 7 in. The sleeve length L (Length) (in) is available in 1 1/2, 1 3/4, and 2.

In die-set design, the sleeve length should cover the required guide engagement zone across the full stroke. Choose L so that the press-fit region provides stable alignment without interfering with adjacent tooling components.

• Diameter match: ensure your post diameter falls within A = 1–7 in for press-fit compatibility.
• Engagement depth: select L = 1.5 / 1.75 / 2 in based on required overlap and clearance.
• Fit/tolerance: press-fit applications depend on interference; confirm the governing hole OD / post OD tolerances in your build drawing and supplier spec before finalizing the interference amount.
