Press-Fit Bushings

A press-fit bushing is a mechanical component that creates a precise and durable connection between two parts when assembling. Carr Lane Mfg. press-fit bushings are permanently pressed into the jig plate and are generally used in single-operation drilling or reaming.

The press-fit bushing inserts into a hole in one of the parts with an interference fit. An interference fit means that the outer diameter of the bushing is slightly larger than the inner diameter of the hole it is being inserted into. As a result, it requires force to be pushed into the hole. This creates a tight and secure fit between the bushing and the surrounding material.

Press-fit drill bushings come in three variations, including press-fit, head press-fit, and serrated press-fit bushings. Each press-fit bushing is made with stress-proof steel and is available in other materials by special order. Carr Lane Mfg. press-fit drill bushings are DFARS & RoHS-compliant and available in various standard drill sizes.

Bearing: They can act as bearings to reduce friction between rotating or sliding components.

Alignment: They help align and position components accurately to ensure proper functioning and reduce wear and tear.

Load distribution: Bushings can distribute forces and loads between different parts, preventing damage due to concentrated stress.

Wear resistance: They offer increased wear resistance to the assembly and are replaceable if they wear out over time.

Bearings: Press-fit bushings are used in machinery and equipment to support rotating or oscillating shafts. They provide a low-friction interface between the shaft and the surrounding structure, reducing wear and ensuring smooth operation.

Automotive Industry: Widely used for various purposes. Found in suspension components, such as control arms or sway bars, providing a stable connection between moving parts.

Electronic Components: Press-fit bushings are used in electrical and electronic devices to provide mounting and grounding points. They can be used to secure connectors, switches, or other components to ensure proper alignment and electrical contact.

Tooling and Fixtures: They are utilized in tooling and fixtures to locate and support workpieces accurately. They help maintain precise alignment and prevent movement during machining or assembly operations, improving accuracy.

Aerospace and Defense: Press-fit bushings are used in various aircraft components, such as control systems, landing gear, and engine assemblies, providing stability and reducing vibration.
