LFB Plain Guide Bushings for Die Sets with Oil Groove, Loctite Adhesive

This LFB plain guide bushing variant is used in die set leader and alignment systems, where a stable guide interface is required to control die-to-die position during repeated press cycles.

• Automotive and industrial stamping die sets: the oil groove supports lubrication at the guide contact, helping reduce friction and wear as the press cycles repeatedly.
• High-frequency production dies: the copper alloy plain guide design is suited for predictable wear behavior and smooth movement, supporting consistent alignment over long runs.
• Maintenance-friendly leader bushings: because this is a bushing-only supply bonded with Loctite adhesive, it can be configured for service-ready rebuilds without relying on fully assembled subcomponents.

The combination of oil groove geometry plus Loctite adhesive bonding makes it appropriate when you need reliable positional control with a simple, low-friction guide interface.

These plain guide bushings use a copper alloy body to support smooth sliding behavior and consistent wear characteristics at the die guide interface. Copper-alloy guides are typically selected where stable friction and manageable wear are critical for alignment during repeated cycles.

• Heat treatment state: the provided specifications do not include an explicit heat treatment process (e.g., quenched & tempered, nitrided) or a target hardness value in HRC.
• Wear vs. toughness trade-off: copper alloy guide materials generally prioritize stable wear behavior over extreme hardness, which can be advantageous for guide systems running lubricated contact.
• Manufacturing approach: delivered as a bushing-only component intended for mounting using Loctite adhesive, which helps maintain positioning without requiring a separate mechanical retention design as part of the supply.

If you need a specific HRC or hardened/treated condition for your die environment, confirm the available material processing with the supplier before final design freeze.

Select the bushing based on the inner diameter d and the length L required to match your leader shaft and guide support geometry in the die set.

• Inner diameter d (mm): choose from 20, 22, 25, 28, 32 to match the leader/shaft diameter used in your die.
• Length L (mm): choose from 50, 60, 80, 100 to cover the intended guide engagement length in the die block/bushing pocket.

To ensure proper alignment, match d to the leader shaft such that the radial clearance supports lubrication and smooth sliding; the exact clearance and tolerance depend on your shaft size tolerances and the guide bore specification in your die housing.

• Fixed vs. configurable dimensions: in this listing, d and L are fixed to discrete options (no continuous customization).
• Mounting consideration: because the unit is bonded using Loctite adhesive, verify the bushing pocket surface finish/fit and adhesive cure conditions to maintain alignment after assembly.
