The Bosch Rexroth STD.LINEAR BUSHING KBM-5 (R060030500) is a robust and precision-engineered linear bushing designed for smooth linear motion in challenging environments. This standard metal linear bushing is closed, offering a rugged all-metal design with a steel ball retainer that makes it suitable for use in harsh conditions such as woodworking, foundries, and cement plants. The KBM-5 bushing is characterized by its ability to withstand heavy contamination while maintaining performance due to its many pockets that act as lubricant reservoirs. These pockets also serve to collect dirt and debris, preventing the bushing from jamming. The outer sleeve of the KBM-5 is hardened and ground, ensuring durability and consistent operation. It features rows of balls made of rolling bearing steel without seal, allowing for higher permissible ambient temperatures with shaft diameters 12 mm and above. The absence of wiper seals means the bushing can operate at higher temperatures but still maintains integrated steel retaining rings for added structural integrity. With a dynamic load capacity based on a total travel distance of 100 km (and adjustable based on 50 km), this linear bushing ensures long-term reliability. The friction coefficient ranges from 0.01 to 0.25 under lubrication with oil, and although it's lowest under heavy loads, it can vary depending on the operational conditions. The STD.LINEAR BUSHING KBM-5 has an outer diameter D of 35 mm, a breakaway force of 7 N, and can handle maximum accelerations effectively. Weighing approximately 0.2 kg, this product offers an optimal balance between weight and performance. Its design allows for extended lubrication intervals or even lubrication for life in certain applications due to its inherent features that cater to self-lubricating properties under operational use. Product applications range from linear motion systems requiring high load capacities to those where frequent exposure to contaminants is expected. The Bosch Rexroth STD.LINEAR BUSHING KBM-5 stands out for its durability and ability to maintain smooth operation despite adverse conditions or heavy particulate presence.

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).

Linear bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
