The Bosch Rexroth STD.LINEAR BUSHING KBM-12-D (R060101210) is a state-of-the-art linear motion component designed for precision and durability. This standard metal linear bushing is closed with one seal and tailored for self-supporting shafts, featuring a rugged all-metal design with a steel ball retainer suitable for harsh environments and heavy contamination. The KBM-12-D is equipped with many pockets that act as lubricant reservoirs to facilitate extended lubrication intervals or even lifetime lubrication, enhancing the maintenance-free operation. The bushing's steel balls are made of rolling bearing steel, ensuring reliable motion and load-bearing capabilities. It is specifically constructed to accommodate shaft diameters, providing versatility in application. With no wiper seals but integrated steel retaining rings, this linear bushing can withstand higher temperatures when used with shaft diameters 12 mm and above. The hardened and ground outer sleeve ensures high precision and smooth movement. This Bosch Rexroth linear bushing boasts an impressive maximum dynamic load capacity (Cmax), which varies based on total travel distance. It has been engineered to maintain performance even in challenging conditions such as woodworking, foundries, and cement plants where dirt ingress is a common issue—the pockets within the design work effectively to prevent jamming by collecting any dirt that may enter the system. With its robust construction, the KBM-12-D offers low friction coefficients when lubricated with oil, contributing to efficient operation under various loads. The permissible ambient temperature range for this model spans from -30°C up to +80°C, allowing it to operate effectively across diverse environmental conditions. Weighing just 0.1 kg, it provides an excellent balance between strength and weight for optimal application in industrial settings. Overall, the Bosch Rexroth STD.LINEAR BUSHING KBM-12-D (R060101210) represents an advanced solution for linear motion requirements demanding high reliability and long service life under tough industrial conditions.

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).
