igus announces next generation of its DryLin R linear bearing

igus (UK) Limited today announced the next generation of its DryLin R linear bearing. New DryLin R showcases design changes in its glide pads and axial fastener, resulting in a longer lifespan, higher precision and increased load capacity.

The maintenance-free, dry-running linear technology behind DryLin R makes it an ideal substitute for traditional ball bearings, especially in harsh, debris-infested or water-based environments.

By changing the design of the glide pads from curved to flat, igus has reduced the clearance between liner and shaft by 50 percent. The contact area is increased to 80 percent, thereby improving the overall load capacity of the bearing. Users of the new DryLin R will also experience higher precision between bearing and shaft.

With a lower initial clearance, new DryLin R bearings have a longer lifespan. Previously, a DryLin R bearing carrying a 10kg load at a speed of 0.125m/s could expect to travel 360km. The new enhancements now enable DryLin R to travel up to 925km in that same application, more than doubling life expectancy.

The new design of the axial fastener provides added stability to the bearing and secures it tighter within the outside housing. With less play,customers are reassured of the stability of the overall application. igus gives the option of supplying the bearings and housing separately, providing more choice to customers and enabling them to use their own housing if desired.

DryLin R was developed for round shafts and applications with a need for high speed and low noise. It is maintenance-free, simple to install and insensitive to dirt. DryLin R is composed of the self-lubricating polymer iglidur J. DryLin R is also self-lubricating, which means it requires no oil or grease, which can contaminate the bearing.

With channels that enable the flow of dirt and dust, DryLin R bearings do not need to be sealed. Its simple design prevents debris from being lodged in the liner and causing irreparable damage, unlike recirculating ball bearings.

DryLin R bearings can reach speeds more than four times faster than recirculating ball bearings, deliver unrestricted acceleration, and are well-suited for high-frequency, short-travel applications. Even at top speeds, DryLin R bearings are extremely quiet.

DryLin R linear bearings, part of igus' full line of iglidur polymer bearings, are an ideal choice for use with stainless steel and aluminum shafting and they can perform in rotary, linear or oscillating motions.
