Self-Lubricating Bearings – High Performance, Standard Guide Bushing Components for Plastic Moulds
Guide Bushing, bronze with graphite straight type. Copper Guide Sleeve: A Self-Lubricating Bushing Engineered for High-Temperature and Submerged Applications Where Plastics Underperform. Tailor-Made Solutions Utilizing Plain Bearing Technology.
Copper Self-Lubricating Guide Sleeves, also recognized as copper bushings, stand out for their ability to deliver a hassle-free, high-efficiency bearing experience across various settings. These components excel in scenarios where traditional oil lubrication falls short or is non-existent, making them perfect for tasks involving significant weight and reduced motion speeds. The innovation in these guide sleeves lies in the selection of specific copper alloys and the integration of solid lubricants like graphite or PTFE (Polytetrafluoroethylene), ensuring self-lubrication.
Key Characteristics and Uses
- Self-Lubrication: The hallmark of these copper guide sleeves is their capacity for operation sans external lubricants, thanks to solid lubricants embedded within the copper alloy framework.
- Designed for Heavy Loads and Slow Movements: These sleeves are optimized for situations that entail substantial loads and slow speeds, where conventional lubrication might falter or be infeasible.
- Composition: Fabricated from robust copper alloys such as CuZn25Al6Fe3Mn3, these bushings offer superior resistance to wear and tear. The inclusion of solid lubricants, primarily artificial graphite and PTFE, amplifies their self-lubricating capabilities.
- Wide-Ranging Applications: Their sturdy construction and self-lubricating feature make these guide sleeves versatile, finding uses across manufacturing, automotive, and aerospace sectors. They are especially beneficial in settings where maintenance challenges persist or where standard lubricants could cause contamination.
- Zero-Maintenance: A notable benefit of these guide sleeves is their prolonged lifespan without the need for upkeep, thereby minimizing downtime and operational costs.
Installation and Usage Guidelines
Although designed for maintenance-free use, it’s advisable to reduce lubrication intervals initially after installation to guarantee peak performance. These guide sleeves are capable of functioning without oil in both air and underwater environments, ensuring adaptability in usage.
Plastic mold is a tool for the plastic processing industry and plastic molding machines to give plastic products with complete shape and precise size. Because of the variety of plastic and processing methods, plastic molding machines,s and plastic products, and the structure of the simple and complicated, so, the plastic mold types and structures are also a varied of guide bushing.

SPB copper self-lubricating bushing
Similar Oilless bushing Type JDB/SOB/MPBZ/303SP
SPB guide bushig is made of high-force brass, and the embedded solid lubricating materials are mainly solid lubricants based on artificial graphite and PTFE.
According to the bearing’s own conditions, the combination of different metal substrates and embedded solid lubricants can ensure that the product can meet the special needs of various temperature, load, movement, and media conditions, and ensure stable and reliable work.
Solid lubricated bearings are especially suitable for no oil, high temperature, high load, low speed, anti-fouling, anti-corrosion, anti-radiation, as well as in water or vacuum solution infiltration and can not add lubricating film under special conditions.
Guide Bushing Features:
1. Can work continuously under the condition of no oil lubrication.
2. More suitable for heavy load and low-speed conditions, with good wear resistance and very low friction coefficient.
3. Suitable for reciprocating, rotating, and intermittent motion where oil film is difficult to form.
4. With corrosion resistance and chemical resistance.
5. Suitable for -40℃+300℃ temperature range.
6. Maintenance-free, long service life.

Standard Clearance Between the Self-Lubricating Bush and the Shaft
The standard clearance between a self-lubricating bush and the shaft is generally aimed to be minimal to achieve more precise linear and rotary motion. However, for oiled bronze bushings, which can be similar in application to self-lubricating bushes, a typical clearance on the diameter is about .001″ (1 thousandth of an inch) with an allowable error range up to .002″ (2 thousandths of an inch) for optimal performance. While specific clearances can vary depending on the application, material, and design requirements, keeping the clearance small is critical for high precision and performance, as noted in contexts where oil-free or self-lubricating bushings are used to ensure precise linear/rotary motion.
