The Bosch Rexroth STD.LINEAR BUSHING KBM-O-40-VD (R063204005) is a high-quality, fully sealed standard linear bushing designed for demanding applications that require reliable linear motion. This rugged all-metal open design features a steel ball retainer, making it suitable for harsh environments and heavy contamination. It is equipped with many pockets that act as lubricant reservoirs to extend lubrication intervals or even allow for lubrication-free operation. The bushing's sealfree construction with steel ball retainers enables it to withstand temperatures well above 100°C or under vacuum conditions. The KBM-O-40-VD is engineered with a hardened and ground outer sleeve and balls made of rolling bearing steel, ensuring durability and smooth motion. It has four rows of balls, providing robust dynamic load capacity. The product comes without wiper seals but includes integrated steel retaining rings which can tolerate higher temperatures for shaft diameters of 40mm and above. This linear bushing is particularly useful in applications such as woodworking, foundries, and cement plants where dirt and debris are common. Its design helps to collect any contaminants to prevent jamming of the mechanism. The bushing's size E has an outer diameter D of 62mm, a breakaway force of 5N, a maximum permissible linear speed (vmax) of 5m/s, and dynamic load capacity C of 1660N. With a weight of 0.4kg and radial clearance specifications tailored to various needs (shaft hbore K or shaftbore hH), the Bosch Rexroth STD.LINEAR BUSHING KBM-O-40-VD offers versatility for different mounting conditions. Its friction coefficient ranges from 0.01 to 0.02 under lubricated conditions, ensuring efficient operation even under varying loads. The permissible ambient temperature range for this model extends from -30°C up to +80°C without seals, accommodating a wide range of operating environments.
