Module series SK

The linear modules of SK series are created on the basis of KK series, but the carriage of module in this case has a plastic seperator of the balls. Due to SynchMotion technology the rolling elements are located in the carriage separately to each other, this reduces the parasitic friction between the rolling elements - balls - and the noise level. The linear modules of SK series can be used in the low noise requirements at relatively high speeds of movement.


Linear Modules Series SK



Linear modules of SK series

Technology SynchMotionTM: Due to SynchMotionTM technology, the rolling elements are located in the system separately to each other, that considerably improves their circulation and reduces the noise level.

Technology of tangent circulation: The balls come into the circulation system by a spiral arc. This reduces their impact load, improves the speed characteristics, acceleration, smooth motion, as compared with the standard system, and reduces the noise level.

The service life calculation

There are three main components that affect on the service life of the linear modules of SK series: ballscrews, rail guideways and bearings

 

Rail guideway 

L=(ft/f∙C/Pn ) 3 ∙50 km

L: Service life (km);
ft: Coefficient of contact;
fw: Load factor;
C: Dynamic load capacity;
Pn: Calculated load (N).

Block type Contact Coefficient ft
A1 1.0
A2 0.81



Operating Condition Loading Coefficient fw
Thrust and Vibration Velocity (v)
No Thrust V﹤15m/min 1.0-1.5
Low Vibration 15m/min﹤V﹤60m/min 1.5-2.0
High Vibration V﹥60m/min 2.0-3.5

 

Ballscrew and bearing

L=(1/f∙Ca/Pa,n)3 ∙106  rev

L: Service life (km);
fw: Load factor;
Ca: Basic dynamic load capacity (N);
Pa,n: Axial load (N).
