The Bosch Rexroth STD.LINEAR BUSHING KBMT-16-DD (R065051600) is a robust and reliable component designed for linear motion applications that demand high durability and resistance to harsh environments. This standard metal linear bushing features a tandem arrangement and comes with two integrated wiper seals to protect against contamination from heavy dust and debris, making it an ideal choice for use in challenging conditions such as woodworking, foundries, and cement plants. The KBMT-16-DD is engineered with a hardened and ground outer sleeve that ensures stability and longevity. Its POM ball retainer holds the balls made of rolling bearing steel, which are arranged in multiple rows to facilitate smooth motion. The design includes many pockets that act as lubricant reservoirs, extending the intervals between lubrication or potentially allowing for lubrication for life. These pockets also serve to collect any dirt ingress, preventing the bushing from jamming. With a shaft diameter of 'd' and an outer diameter 'D', this linear bushing is designed to accommodate standard shaft sizes. The maximum dynamic load capacity (Cmax) indicates the bushing's ability to handle loads during operation over a total travel distance of 100,000 m; this value can be adjusted based on different travel distances as specified in the footnote regarding Cmin and Cmax values. The STD.LINEAR BUSHING KBMT-16-DD operates efficiently within a permissible ambient temperature range, ensuring reliable performance under varying environmental conditions. The product's weight of 0.2 kg reflects its solid construction without compromising on the ease of installation or movement. Overall, this Bosch Rexroth linear bushing is built to offer precision movement in linear guiding applications where durability and resistance to contamination are paramount. Its design considerations cater to extended service life and reduced maintenance needs in industrial settings with challenging operating 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).
