The Bosch Rexroth STD.LINEAR BUSHING KBM-E-80-D (R061108010) is a high-quality linear motion component designed for reliable and precise linear movement in demanding industrial environments. This standard metal linear bushing is adjustable and comes equipped with one seal, enhancing its durability and performance in harsh conditions. It features a rugged all-metal design with a steel ball retainer, making it suitable for heavy contamination areas such as woodworking, foundries, and cement plants. The KBM-E-80-D has many lubricant reservoirs which contribute to extended lubrication intervals or even allow for lubrication-free operation throughout its life. Its integrated wiper seals protect against high levels of contamination while the steel ball retainers ensure functionality at temperatures well above 100°C or under vacuum conditions. The radial clearance of this bushing is adjustable to suit various application requirements. The outer sleeve of the bushing is hardened and ground for additional robustness, while the shaft diameters of 50mm and higher feature a plastic retainer made from PA material. The rolling bearing steel balls are arranged in multiple rows within the series standard metal construction. This model's dynamic load capacity reaches Cmax values that account for total travel distances, ensuring long-term performance. In terms of technical specifications, the STD.LINEAR BUSHING KBM-E-80-D has a size E designation with an outer diameter D of 80mm. It can handle maximum dynamic loads with specific friction coefficients outlined in its detailed specifications. The permissible ambient temperature range for this bushing spans from -30°C to +100°C, accommodating a wide range of operating environments. Overall, the Bosch Rexroth STD.LINEAR BUSHING KBM-E-80-D provides a reliable solution for linear motion applications requiring precision under challenging conditions. Its design focuses on longevity and efficient operation, making it an essential component for industrial machinery where downtime is not an option.

Impact of load direction on load rating of closed Linear Bushings

The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.

Definition of dynamic load ratings

Installation dimensions/interchangeability

Standard Linear Bushings have the same installation dimensions as super Linear Bushings. They are interchangeable, differ however in terms of securing, radial clearance, load ratings and lubrication.

Sealing

Standard Linear Bushings come with a wiper seal with shaft diameters of 5 and higher. Open standard Linear Bushings with shaft diameters 20 to 80 can also come fully sealed (with longitudinal seal; increased friction).
