LFBZ Plain Guide Bushings for Die Sets (Oil-Free Copper Alloy) Loctite Bonded

Plain guide bushings are used in die set guide systems where stable alignment between the upper and lower tooling directly impacts part quality and cycle reliability.

In automotive stamping and progressive die assemblies, these oil-free copper alloy bushings help maintain consistent sliding motion with reduced dependence on external lubrication, supporting smooth leader/die wear behavior over repeated press cycles.

For high-frequency blanking or forming stations, the Loctite-bonded retention approach supports stable seating in die plates, reducing the risk of micro-shift that can lead to misalignment, edge variation, or uneven wear.

In multi-cavity or long-stroke die sets, selecting the correct inner diameter and length from the available ranges (d: 20–32 mm, L: 50–100 mm) ensures the bushing spans the guided region needed for controlled die motion.

• Oil-free copper alloy supports low-lubrication operation.
• Loctite bonded mounting improves retention during press cycles.
• Plain guide bushing (LFBZ) suits leader/ejector-space die alignment requirements.

This LFBZ plain guide bushing uses an oil-free copper alloy selected for stable sliding behavior in die set guide applications. The oil-free copper alloy formulation is intended to reduce lubrication requirements while supporting predictable wear characteristics under repeated motion.

The product is Loctite adhesive bonded into the die assembly, meaning the retention relies on proper adhesive cure and surface preparation to maintain positional stability under press load and vibration.

• Wear resistance: optimized for guide surfaces where controlled sliding and consistent alignment are required.
• Toughness trade-off: copper-alloy guide materials typically balance good bearing behavior with moderate strength versus high-hardness tool steels.
• Heat treatment: no specific steel grade or HRC value is provided in the available specifications, so hardness/tempering details cannot be stated for this variant.

To select the correct bushing, match the inner diameter (d) and length (L) to the leader/guide geometry and the effective guide zone in your die set.

• Inner diameter d (mm): choose from 20, 22, 25, 28, 32 based on the leader shaft diameter requirement.
• Length L (mm): select 50, 60, 80, 100 to cover the guidance length needed for stable die motion.

During design, ensure the bushing length is sufficient to support guided travel without overhang into areas that can interfere with plates or return components. Because no tolerance values are provided in the input data, confirm the required fit class with your own drawing tolerances and the die plate reaming/bore machining plan before finalizing the assembly.

Use the fixed available sizes as configurables for d and L; other dimensions are not listed in the provided specifications.
