What is the Bosch Rexroth R169489410?

The ball runner block is highly precise and characterized by the following product features:

Size 20

Format SNN: Width = slimline, length = normal, height = low

Runner block body made of unalloyed steel CS

Preload class C0: Preload-free

Accuracy class N: Standard

Without ball chain

Preserved

Without initial lubrication

Without attachment element, left (front reference edge)

Without attachment element, right (front reference edge)

45° angular lube nipples loosely attached.

Runner block body in standard version

Overall length of the runner block = 72.5 mm

Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.

Area of application: For restricted upward and longitudinal space

Maximum precision

Patented entry zone increases the travel accuracy up to a factor of six

Significantly reduced frictional oscillations and low friction force level, particularly under external load

Long-term lubrication is possible over several years

Lube fittings with metal threads on all sides

End-face fastening thread for all attachments

Integrated all-round sealing

High torque load capacity

Preload classes: C0 (without preload, clearance) and C1 (moderate preload)

Optional integrated, inductive and wear-free measuring system

Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection

Can be used on all SNS/SNO ball guide rails
