Edm Bearings

Product Description

EDM 624 and 625 Bearings refer to specific types of miniature bearings used in Electrical Discharge Machining (EDM) or in EDM-related equipment. These bearings are designed to handle the high-precision requirements of EDM processes and are commonly found in EDM machines where precise motion control is needed.

Key Features and Specifications of EDM 624 and 625 Bearings:

1. Bearing Types:

   • 624 Bearing and 625 Bearing refer to specific sizes in the miniature ball bearing category. These bearings are commonly used in machines like EDM wire machines, sinker EDMs, and other precision tools where low friction and accurate rotational motion are required.

2. Size:

   • 624 Bearing typically has an inner diameter of 4mm, an outer diameter of 13mm, and a width of 5mm.
   • 625 Bearing is slightly larger with an inner diameter of 5mm, an outer diameter of 16mm, and a width of 5mm.
   • These sizes make them well-suited for applications where compact dimensions are necessary, such as in spindles or rotating parts of EDM machines.

3. Material:

   • EDM 624 and 625 bearings are usually made from high-quality steel for durability and precision. Some bearings may feature stainless steel or ceramic materials depending on the application™s requirements, particularly in environments with high levels of heat or corrosion.

4. Ball Bearing Construction:

   • Both 624 and 625 bearings are typically ball bearings, meaning they use balls as the rolling elements between the inner and outer rings. This construction minimizes friction and wear, providing smooth rotational movement for the machine components they are installed in.
   • The design also allows for the reduction of radial and axial loads, helping maintain the precision of the machine components.

5. Precision and Tolerances:

   • EDM applications require high-precision bearings to ensure that small movements and delicate machining processes are carried out without any vibrations or irregularities.
   • These bearings typically come with ABEC 1, ABEC 3, or ABEC 5 tolerances, with ABEC 5 offering the highest precision. The tighter the tolerance, the better the bearing's ability to maintain accuracy at high rotational speeds.

6. Lubrication:

   • Bearings used in EDM machines, including 624 and 625 bearings, may come pre-lubricated or require grease or oil lubrication to reduce friction. In some EDM systems, dry lubrication or sealed bearings may be used to maintain cleanliness in the machining area and avoid contamination from dielectric fluids or debris.
