Bushing XA: page 6
Made from sintered powder bronze, XA bushings are one of the most versatile solutions for reducing friction in agricultural and industrial machinery.
The sintering process used to produce the porous bronze of XA bushings compresses the metal powder at high temperatures without complete melting, leaving a network of micro-channels within the material’s structure capable of retaining lubricant. This structure acts as an internal reservoir, which gradually releases oil during operation and is partially replenished when the equipment is at rest – a notable advantage for machinery used intermittently.
How XA bushings help reduce friction and wear
The porous structure of the sintered bronze from which XA bushings are manufactured retains a small amount of lubricant within the material’s pores, which is gradually released during operation. This self-lubricating principle reduces direct metal-to-metal friction and, consequently, wear on both the bushing and the shaft or pin with which it comes into contact.
The versatility of XA bushings in agricultural and industrial machinery
Thanks to this design, XA bushings are used in a wide range of applications — from stabilisers and articulated arms to steering systems on agricultural machinery. For similar mounting locations, EB65.02 bushings and JDB bushings offer additional self-lubricating options, whilst for identical mounting, the XA bushing range and E92 bushings complete the same range of applications.
The benefits of buying XA bushings from Hydraulic Seals Store
Hydraulic Seals Store stocks XA bushings in various sizes, with clear technical data sheets for each product. Ordering online is quick, and delivery arrives in time for scheduled maintenance or repairs that cannot be delayed.
As one of the most versatile solutions in the bushing category, the XA series covers a wide range of sizes, clearly listed in each product specification sheet. For agricultural machinery with multiple pivot points exposed to dust and moisture, combining XA bushings with the appropriate oil seals from the same range ensures a durable repair.
