The Bosch Rexroth SUPER LINEAR BUSH KBA-10 (R067001000) is a high-quality linear bushing designed for smooth and precise linear motion applications. This model, part of the Super LB A series, features a closed design without seals, making it an economical option for high-performance requirements. The SUPER LINEAR BUSH KBA-10 is equipped with steel bearing plates that have been meticulously machined to include ball guide grooves and optimized chamfers, ensuring exceptionally smooth travel and a long service life. The bushing's self-aligning feature allows it to compensate for shaft deflection and misalignment, maintaining high travel speeds of up to 5 meters per second. It does not require initial lubrication, which simplifies maintenance tasks. The ball retainer and outer sleeve are constructed from durable PA or POM materials, while the balls themselves are made from rolling bearing steel, arranged in multiple rows to enhance load distribution and performance. The SUPER LINEAR BUSH KBA-10 can handle a maximum dynamic load capacity (Cmax) and is capable of withstanding accelerations up to specified values. Its permissible ambient temperature range is from -20°C to 80°C. The outer diameter (D) dimension ensures compatibility with corresponding shafts, while the product's weight remains low at 0.2 kg for ease of integration into various systems. This linear bushing can achieve total travel distances significantly high without failure, as demonstrated by rigorous testing. The friction force and coefficients are optimized for minimal resistance during operation; however, these values may vary depending on factors such as load and lubrication conditions. Overall, the Bosch Rexroth SUPER LINEAR BUSH KBA-10 offers reliability and precision in linear motion applications where cost-effectiveness does not compromise on quality or capability. Its robust construction and self-aligning feature make it suitable for various industrial uses where smooth operation and longevity are critical requirements.

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.

Reduced load capacity with short stroke

In case of short stroke, the service life of the shaft is less than that of the super Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .

1)	fs = factor
2)	s = movement path

Reduced load capacity with high load

If the load F on a Super Linear Bushing A is more than F > 0.5 x C, the dynamic load rating C decreases.

Definition of dynamic load ratings

Self-alignment feature

The self-alignment feature in the steel bearing plates and machined ball guide grooves ensure quieter travel. The flow chart shows a comparison with a conventional Linear Bushing. The example is based on a load of 800 N and misalignment of about 8 ft (caused by shaft deflection).

Due to the self-alignment feature, two super Linear Bushings must be used on at least one of the shafts in the guide.

	FR = Frictional drag
	s = travel distance
	v = travel speed

Sealing

Super linear bushings come both with integrated and separate wiper seals. The separate wiper seals are specially designed for applications in high contamination environments. An additional seal (for example, bellows, extendable cover) is necessary for extremely high contamination environments. The open super linear bushings can also come fully sealed (with longitudinal seal), however this increases friction.

Life expectancy calculation

Radial clearance

The radial clearance values shown in the table have been determined from statistics and correspond to values expected in practice.

Adjusting radial clearance

The radial clearance of all Linear Bushings can be adjusted. If, for instance, a zero-clearance guideway is needed, the radial clearance of the Linear Bushing must be reduced using the adjusting screw on the housing (see also Linear Sets) until slight resistance occurs when rotating the shaft. Secure the adjusting screw for applications where vibrations are present.

Adjusting preload

For preloading, the aforementioned adjustment is made using an adjustment shaft that is weaker by the degree of preload.

General mounting instructions

Initial lubrication

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.
