The reduction of the bearing operating temperature is an important aspect for the optimization of bearing arrangements and therefore of machine tools as a whole. Low temperatures stand for operational reliability and enhanced precision. At the same time they enable speed increases. Apart from suitable materials and lubricants, the channeling of the lubricant is a relevant factor for reducing the friction inside the bearing, particularly in high-speed applications. This becomes apparent when considering the enormous temperature reductions that can be achieved with the new FAG Low Temperature bearings. Their new internal design is based on the realization that the contact area where the cage is guided, strongly gains in importance with increasing speeds. FAG Low Temperature spindle bearings operate at up to 10 % lower temperatures, achieved through corresponding adjustments of cage and channeling of the lubricant. Conversely this new bearing generation opens up the potential for speed increases of up to 10%. The operating reliability of the bearings increases correspondingly; machinery downtime and system costs are reduced.The advantages of the new internal TX-cage design are so convincing that all FAG spindle bearings will in the future be offered in this new generation, irrespective of design and series. As in the past with the introduction of sealed bearings or X-life ultra bearings, FAG once again sets a new standard for the machine tool industry.

The modified guidance of the lubricant at the cage contact area leads to clearly reduced friction inside the bearing. Compared to other spindle bearings currently available in the market, FAG Low Temperature bearings run 10% cooler.

The new TX cage design will become the standard for all FAG spindle bearing series and configurations. Consequently there will be a change in the current nomenclature ("T" becomes "TX" starting from June 1st, 2006).

- up to 10 % cooler

- up to 10 % faster

- higher operational reliability

- extended uptime

- reduced system costs

- incorporating tomorrow`s standard today
