The Bosch Rexroth SUPER LINEAR BUSH KBA-40-D (R067014040) is a high-precision linear motion component designed for smooth and efficient linear movement. This model features an advanced self-alignment capability, which allows it to compensate for shaft deflection and misalignment, ensuring reliable operation even in demanding applications. The bushing is closed with one seal, providing protection against contaminants while maintaining a low friction coefficient. With a shaft diameter of 40 mm, the KBA-40-D is equipped with steel bearing plates that have been meticulously machined to create ball guide grooves with optimized ball lead-in chamfers. This design detail contributes to the bushing's exceptionally smooth travel and extended service life. The integrated wiper seals help maintain cleanliness within the system, further enhancing the product's durability. The unit can handle high travel speeds of up to 5 meters per second, although this may limit service life due to increased wear on plastic parts. However, tests have shown that total travel ranging from 100 million mm to 200 million mm is achievable without failure. The SUPER LINEAR BUSH also boasts an impressive maximum dynamic load capacity and can operate efficiently within a temperature range of -20°C to +80°C. The outer diameter of the bushing is precisely crafted for compatibility with corresponding linear shafts, and it exhibits a breakaway force that ensures stability under load. With its low friction coefficient, ranging from 0.01 to 0.25 depending on conditions, and a minimum dynamic load capacity calculated based on total travel distances, this linear bushing ensures consistent performance. The KBA-40-D weighs approximately 0.45 kg and offers various radial clearances for different shaft tolerances, ensuring a perfect fit in diverse applications. Its ball retainer and outer sleeve are made from durable materials like PA or POM, while the balls themselves are constructed from high-quality rolling bearing steel. This combination of materials and design attributes makes the Bosch Rexroth SUPER LINEAR BUSH KBA-40-D (R067014040) an ideal choice for applications requiring precise linear movement with minimal frictional resistance.
