Overview

Flange extended BSHP ball slider FLS, standard, steel application range: suitable for applications with stiffness requirements, significantly reduces friction vibration and low friction levels, especially in dynamic characteristics under external load conditions. The inlet area has won the award for precision, improving operational accuracy by six times. Friction is provided in all load directions due to Bosch Rexroth's four row ball design, which provides two-point contact in all load directions

friction

Due to Bosch Rexroth's four row ball bearing designSo provide in all load directionsTwo point contact. This minimizes friction.

Other four point contacts with two or four rows of ball bearingsBall guide systemAffected by multiple frictions: Due to the slip of lateral loads, if there is a considerable amount of prestress without load, the Gothic guide rail structure will generate significant frictional forces (depending on the curvature and load of the guide rail, the friction coefficient can increase by five times). This high friction leads to the generation of more heat.

sealing element

Seals are used to prevent dust, debris, and coolant from entering the interior of the ball slider during operation, thereby preventing its service life from being shortened. For detailed information, please refer to "Selecting Standards/Seals".

Standard Seal (SS)

Universal seals are standard accessories in Bosch Rexroth ball sliders. They have a universal sealing effect on ball guides with and without protective straps. Consider low friction and good sealing effect in the design process. Suitable for applications that require good sealing conditions.

According to DIN ISO 14728-1 standard, the rated dynamic load and load moment are calculated based on a stroke length of 100000 meters. However, the actual requirement is usually only 50000 meters. In this case, for comparison: compare these values in the tableC、MtAndMLMultiply by 1.26.

General description

General technical data and calculation methods applicable to all ball guide systems (i.e. all ball sliders and ball guides). Specific technical information related to individual ball sliders and ball guides are listed separately.

Pre tightening grade

In order to meet a wide range of application needs as much as possible, Bosch Rexroth offers various levels of pre tensioned ball sliders.

Provide ball sliders with the following pre tightening levels:

Ball slider without preload load (preload grade C0)

Medium preload load ball slider (preload level C1)

Average preload load ball slider (preload level C2)

High preload load ball slider (preload grade C3)

To prevent a shortened service life, the preload should not exceed one-third of the bearing F load.

Usually, the stiffness of ball slider increases with the increase of preload load. If vibration occurs, please select a corresponding high-level preload load (≥ preload level C2).

Guide rail system with parallel guide rails

When selecting the pre tightening level, attention should also be paid to the allowed parallel offset of the guide rail ("Precision Level Selection Standard").

When setting the precision level of the ball guide system to N, we recommend setting the preload level to C0 or C1 to avoid torsional stress caused by tolerances.
