MDB Type Plain Guide Bushings for Die Sets (Oil Groove) Bonded by Devcon Adhesive

Q: What d and L ranges are available for this MDB plain guide bushing (oil groove, Devcon bonded)?

The bushing inner diameter d is specified as 20 ~ 60 mm . The length L is available in the range options: 50 , 50 ~ 60 , 60 ~ 80 , 80 ~ 100 , and 100 ~ 120 mm . LC full length alteration is specified as 25 ~ 101 mm .

Q: How does the oil groove design support guide alignment and wear control in die sets?

This variant includes an oil groove , which is intended to retain lubricant at the sliding guide interface. By supporting better lubrication in the running surface, it helps reduce uneven wear that can degrade alignment over production cycles. It is particularly relevant for precision die sets that require stable lateral guidance.

Q: Is the bushing suitable for bonding into die set housings—what bonding method is used?

The bushing is bonded using Devcon adhesive , which is designed to secure the bushing in the die set without relying solely on mechanical retention. This is useful when you need mounting stability during repeated production loads. For integration, ensure the die housing provides the intended seat geometry for adhesive bonding.

Q: What tolerance/fit guidance is available for matching d to the leader diameter?

The provided specifications list d as 20 ~ 60 mm , but they do not specify clearance or HRC hardness. For fit, you should use your own die design’s clearance/tolerance stack-up to prevent binding while maintaining guide stability. Verify the fit plan against your leader diameter tolerance band.

Plain guide bushings for die sets (MDB type) are built with an oil groove and bonded using Devcon adhesive to support stable die guidance and repeatable alignment. Ideal for die sets where maintenance-friendly wear control is required.

Product Guide

🏭Application Scenarios+

MDB-type plain guide bushings are used in injection and forming toolsets where die alignment must remain stable over repeated cycles. In die sets for automotive connector housings and other medium-precision stampings, the oil-groove geometry helps retain lubrication at the sliding interface, reducing uneven wear and protecting guide performance.

For consumer electronics housings and similar parts that require consistent positioning during insertion and forming, these bushings support repeatable lateral guidance, helping maintain part-to-part dimensional repeatability.

In multi-cavity progressive die applications, secure installation is critical; the Devcon adhesive bonding is suited to maintain mounting integrity so the bushing stays properly seated while forces rise during production.

Oil groove design supports lubrication retention for smoother sliding alignment.
Devcon adhesive bonding improves installation stability in die set housings.
Plain guide bushing construction fits MDB configuration for controlled guide wear.

🔧Material & Process Details+

This product is an oil-groove plain guide bushing bonded with Devcon adhesive. However, no steel grade, heat-treatment condition, or measured hardness (HRC) is provided in the available specifications, so material hardness and wear/toughness trade-offs cannot be stated precisely for this exact part.

From a manufacturing standpoint, the key feature is the bonded mounting approach: the bushing is positioned in the die set and fixed using Devcon adhesive, which supports dimensional stability during service.

Heat treatment: not specified for the bushing substrate in the provided data.
Hardness/wear: not specified in HRC; wear performance is supported by the integrated oil groove for lubrication retention.
Trade-offs: detailed comparisons to alternatives (e.g., nitrided or through-hardened guide components) are not possible without the substrate/material grade.

📐Sizing & Selection Guide+

Correct selection starts with matching the shaft (leader) diameter to the bushing inner diameter d. Choose d in the range of 20 ~ 60 mm so the guide leader can slide without binding while maintaining lateral stability.

Next, confirm the available mounting and support length. The bushing length L is offered as ranges: 50, 50 ~ 60, 60 ~ 80, 80 ~ 100, and 100 ~ 120 mm. Select the longest length that still fits your die set layout to maximize bearing length and reduce localized wear.

For die housing geometry, use LC (full length alteration) in the range of 25 ~ 101 mm to align with the required allowance for full-length positioning and tolerance stack-up.

Match d to leader diameter; verify clearance via your design’s tolerance and fit strategy.
Choose L based on cavity/core spacing and guide support requirements.
Confirm LC against your die set machining/alteration plan.

Frequently Asked Questions
