The Bosch Rexroth STD.LINEAR BUSHING KBM-4 (R060030400) is a high-quality standard linear bushing designed for applications requiring robust performance in challenging environments. This closed-type bushing is crafted without seals, featuring a rugged all-metal design with a steel ball retainer that excels in harsh conditions and heavy contamination. It is particularly suitable for use in woodworking, foundries, and cement plants. The KBM-4 bushing has multiple lubricant reservoirs to facilitate extended lubrication intervals or even lubrication for life. Its steel ball retainer accommodates shaft diameters of various sizes, with plastic strips made of POM or PA depending on the diameter. The hardened and ground outer sleeve ensures durability and smooth motion. Additionally, dirt pockets are integrated into the design to prevent jamming by collecting contaminants. With a dynamic load capacity based on a total travel of 100 km (and an adjusted factor for 50 km), as well as static load capacities provided, this linear bushing can handle significant loads. The permissible ambient temperature range for the unsealed version with steel ball retainers is from -30°C to +80°C, allowing operation in diverse climates without compromising load capacity. The KBM-4's maximum permissible linear speed and acceleration parameters ensure efficient operation, while its friction coefficient remains low under heavy loads but may increase slightly under low loads. Weighing just 0.1 kg, it offers a compact yet powerful solution for linear motion requirements. Overall, the Bosch Rexroth STD.LINEAR BUSHING KBM-4 provides reliable performance with minimal maintenance needs in industrial settings where dust and debris are common challenges.
