Product Guide
Application Scenarios+
Metric low-profile plain guide bushings in demountable style are used in injection die sets and compact leader/guide systems where stable alignment is required during repeated cycling. Their detachable mounting enables quick maintenance or rework without removing the entire die, which reduces downtime on production tooling lines.
- Automotive and industrial connector molds: Use these bushings in ejector/leader guide areas that must maintain straight, repeatable movement. The low-profile geometry helps fit in space-limited guide plates while the plain bearing design supports smooth sliding.
- Precision appliance and electronics housings: They suit die sets needing tight positional stability through short guides and frequent part ejection. Select the bronze-plated option to improve running wear behavior in moderate load, high-cycle applications.
- General forming and die maintenance workcells: Demountable construction is beneficial when wear is localized and periodic bushing replacement is planned. The set supply (clips/screws) supports controlled installation and repeatable service intervals.
Material & Process Details+
These metric guide bushings are offered in bronze plated or steel materials to match wear and duty requirements in guide systems. In plain guide applications, the bearing surface condition directly affects friction and wear rate under oscillating or sliding motion.
- Bronze plated: Typically selected for improved wear resistance and better sliding behavior in service where lubrication may be limited or duty is moderate. The plated surface acts as a sacrificial/low-friction layer compared with base steel.
- Steel: Selected when dimensional stability and higher structural robustness are prioritized. Steel generally offers better toughness, while the surface condition governs wear performance.
Heat treatment details: The specific hardness (HRC) and heat-treatment state (e.g., quenched & tempered, nitrided) are not provided in the available specifications, so they should be confirmed with the manufacturer documentation for this series before final tool qualification.
Sizing & Selection Guide+
Selection is driven by matching the bushing dimensions to the guide system’s leader/bushing fit and the available guide plate space. This series provides variable ranges of D1 = 18–80 mm, D2 = 28–100 mm, and L = 28–92 mm.
- Match inner diameter (D1): Choose a bushing with D1 that corresponds to the leader shaft diameter to achieve the intended sliding clearance in the guide. Verify that the leader diameter falls within the bushing’s D1 range for your die design.
- Match outer diameter (D2): Ensure D2 fits the receiving bore in the guide plate or housing. Use D2 to confirm press-fit/interference expectations and the available material thickness around the pocket.
- Match length (L): Select L to provide adequate guidance while respecting die shut height and build-up. Confirm that L does not interfere with adjacent components and supports full bearing engagement across travel.
Fit/tolerance note: The specification ranges define dimensional envelopes; actual functional clearance and tolerances must be checked against your die drawing and the supplier’s tolerance class for this series before release.
Frequently Asked Questions
What dimension should I use to confirm compatibility with my leader shaft in this demountable guide bushing series?+
Use Dimension D1 (18–80 mm) to match the leader/shaft diameter that the plain bushing will slide on. Confirm your leader diameter falls within the chosen bushing’s D1 range.
Then verify that the guide plate bore and pockets accommodate D2 (28–100 mm).
How do I select the correct bushing length (L) for full guide engagement without exceeding die space?+
Select L (28–92 mm) based on required bearing engagement and the available space in the leader guide assembly. Ensure L provides adequate contact over the leader travel while avoiding interference with surrounding die components.
Because these are low-profile units, use L to fine-tune guidance where height is limited.
When should I choose bronze plated versus steel for a low-profile plain guide application?+
This series is available in bronze plated and steel materials. Choose bronze plated when you need improved sliding/wear behavior for moderate duty guide cycling.
Choose steel when you prioritize structural robustness and rely on the surface condition and lubrication strategy to meet wear targets.
Does the demountable mounting method affect maintenance planning or replacement intervals?+
Yes. The demountable style is designed for detachability, supporting bushing replacement without full die disassembly. This helps maintenance teams plan localized replacement when wear is concentrated in the guide area.
The product is supplied as a set with mounting clips and screws, supporting repeatable installation.
Are hardness and heat-treatment values available for this guide bushing series?+
The provided series specifications list material (bronze plated, steel) and dimensional ranges for D1, D2, and L, but they do not include hardness (HRC) or an explicit heat-treatment state.
For qualification, request the heat-treatment and hardness data for the exact part variant under series code 250300459908.
