Design and version

Friction

technical illustration-R162431422-Ball runner block, SLH, size 35, steel CS, accuracy standard, low preload, with ball chain

Due to the Rexroth design with four rows of balls, 2-point contact is available in all loading directions. This reduces the friction to a minimum.

Other ball rail systems with two or four rows of balls with 4-point contact have multiple friction: due to the differential slip with lateral loading and in case of comparable prestressing without the load, the gothic raceway profile causes higher friction (depending on the raceway curvature and the load, up to five times the friction coefficient). This high friction leads correspondingly to greater heat.

Seals

Seals are use to prevent dirt, chips and coolants, etc. from working their way into the inside of he Ball Runner Block, thereby preventing reductions to its service life. For further information, see "Selection criteria/seals".

Standard seal (SS)

Universal seals are fitted as standard in Rexroth Ball Runner Blocks. They have a uniform sealing effect for Ball Guide Rails with and without cover strips. Low friction and a good sealing effect have both been taken into account in the design. For applications where effective sealing is required.

Low-friction seal (LS)

For special requirements with regard to ease of movement.

Double-lip seal (DS)

For increased exposure to media

Front seal

For applications in environments with fine dirt or metal particles, as well as coolants or cutting fluids.

Interchangeable during servicing.

Front seals are available as accessories for mounting by the customer.

FKM seal

For applications in extreme environments with fine dirt or metal particles, as well as heavy use of coolants or cutting fluids.

Interchangeable during servicing.

FKM front seals are available as accessories for mounting by the customer.

Cover plate wiper

For use in environments with coarse dirt or chips.

Cover plate wiper are available as accessories for mounting by the customer.

General Notes

The general technical data and calculations apply to all Ball Rail Systems i.e. to all Ball Runner Blocks and Ball Guide Rails. Specific technical data relating to the individual Ball Runner Blocks and Ball Guide Rails is listed separately.

Preload classes

To cover the widest possible range of applications, Rexroth Ball Runner Blocks are available in different preload classes.

The following preload classes are available:

Ball Runner Block without preload (preload class C0) Ball Runner Blocks with moderate preload (preload class C1) Ball Runner Blocks with average preload (preload class C2) Ball Runner Blocks with high preload (preload class C3)

To prevent reductions to the service life, the preload should not exceed 1/3 of the load on bearing F.

In general, the rigidity of the Ball Runner Block rises with increasing preload. If vibrations occur, select a correspondingly high preload (≥ preload class C2).

Guide systems with parallel rails

When choosing the preload class, pay attention to permissible parallelism offset of rails too ("Accuracy class selection criterion").

When specifying ball rail systems of accuracy class N, we recommend preload class C0 or C1 to avoid distortive stress due to the tolerances.

Accuracy classes

System preload

a)	For O-ring
	Size 25 - 45: Ø 5 · 1.0 (mm)
	Open lube port and mount the lubrication adapter if necessary (see general technical notes and information in the "Maintenance" section).
b)	Lube nipple, size 25 - 45:
	Hydraulic-type lube nipple DIN 71412-A M6x8, B2 = 9.5 mm
	When using different lube nipples, pay attention to the screw-in depth of 8 mm!
	The lube nipple is included in the scope of delivery (not installed).
	Connection is possible on all sides.
