Miniature linear guideways join motion range
A new range of miniature linear guideways is available in four standard sizes, suitable for dynamic loads up to 6660N.
Modular automation for ink jet coding
Not all coding applications can be met by an ink jet printer in isolation. More often than not, an automation system is required.
Programmable screwdriving at lower cost
The new programmable Werner screwdriver from RA Rodriguez adds considerable value to an already proven multi-axis system.
The four-row bearing configuration is considered to offer an ideal two-point contact structure.
This design offers less differential slip than alternatives and requires low installation accuracy as it has the ability to absorb surface irregularities without compromising its smooth, light motion.
It also ensures virtually no increase in friction when the system is preloaded.
Available in five grades from normal accuracy to ultra-high precision, the RA Rodriguez guideway features a patented circulation system that ensures the ball bearings run smoothly.
The lubrication system is also patented, greatly increasing maintenance intervals and therefore saving costs.
This comprises a self-lubrication block - sufficient for light to medium loads - and the facility to deliver additional lubrication via a manual grease pump for more arduous applications.
A travel distance of 400 km at 50m/min is quoted for a load of 18.6 kN and 3200 km for a load of 9.3 kN.
Primarily introduced to meet the needs of OEMs and in particular machine builders, the range comprises the standard carriage design with and without flanges, in twelve sizes, offering a dynamic load rating of 6850N to 128,500N.
The range also includes a compact version, again available in twelve sizes.
Guide rails up to 4m maximum length can be supplied cut to customer size requirements.
