LDB Plain Guide Bushings for Die Sets

LDB plain guide bushings are used inside die sets to maintain stable alignment between mating components during press or molding cycles. Their oil-groove surface is intended to support lubrication management at the sliding interface, helping reduce friction and wear as the die set repeatedly moves.

Common scenarios include automotive connector and bracket tooling, where guide accuracy must be maintained over long production runs. For these applications, the plain guide bushing style provides a smooth, low-interference bearing surface while the oil groove supports consistent lubrication behavior.

They are also suitable for small-to-medium industrial forming and stamping dies that require predictable die-to-die alignment. In addition, the Loctite adhesive bonding approach helps secure the bushing in place without relying solely on mechanical retention, improving repeatability during cycling.

• Use in leader/ejector space guide positions that require plain bearing performance
• Oil groove supports reduced friction at sliding interfaces
• Loctite bonding supports reliable installation and retention

The provided product data does not specify the exact steel grade, heat treatment state, or hardness (HRC). As a result, material-property claims (e.g., wear resistance level, toughness trade-offs, or whether it is quenched-and-tempered, nitrided, or pre-hardened) cannot be stated accurately for this specific LDB variant.

For guide bushings used in die sets, engineers typically select a bearing-capable steel and then control wear vs. toughness through heat treatment (for example, quench-and-temper for a balanced hardness/toughness profile or surface enhancement like nitriding for improved abrasion resistance). When qualifying this part, confirm the supplied material certificate for the actual grade, target hardness, and any coating or surface treatment.

• No grade/HRC/treatment details were included in the input—verify from datasheet or material test report
• Choose based on the required wear resistance vs. impact/toughness balance for the die duty cycle

Since no numeric dimension specifications (e.g., ID/OD, length, or bushing-to-pocket clearance/tolerance) were included in the provided data, the correct sizing must be verified against the official LDB dimension table for series code 110100160920.

Selection approach:

• Match the bushing-to-die pocket fit: confirm the bushing outer diameter and length against the guide bore/pocket in the die set so the bushing sits fully and squarely.
• Confirm the guide clearance: ensure the internal guide diameter provides the intended running clearance for the mating leader/shaft. This clearance directly impacts friction, alignment stability, and wear.
• Account for adhesive bonding: because this variant uses Loctite adhesive bonding, tolerances should consider adhesive thickness/fit strategy specified by the installation procedure to avoid misalignment.

If dimensions are configurable for your application, confirm which of the LDB geometry parameters (diameter/length) are fixed vs. ordered to print—then lock the final fit before machining the die pocket.
