Why do large spherical plain bearings get the “X-life” seal of approval?
For years now, INA-Schaeffler KG has been the market leader with its ELGES Maintenance\-free spherical plain bearings. The performance of these bearings has been improved, and they are being sold with a new seal of approval called “X-life”. INA and FAG have started to use this to designate their premium products and services for industrial applications. The decisive factor for including our spherical plain bearings in this group was the improved Elgoglide® coating: Dynamic and static load ratings have been increased by 50 %, and the potential service life can be up to eight times higher than that offered by our competitors. Since the coating is completely resistant to moisture, these bearings are also suitable for Hydraulic steel structures – an industry that is extremely sensitive from an environmental protection point of view. X-life large spherical plain bearings are available with shaft diameters starting at 320 mm (radial) and 220 mm (thrust).
Buenos Aires. The Puente de la Mujera pedestrian bridge in the old harbor is a master achievement, both architecturally and technically. This is also true for the bearing positions of the pivoting bridge section for which a zero-maintenance period of 50 years is required. This is no problem for ELGES large spherical plain bearings and represents premium quality made by INA that deserves the “X-life” seal of approval.

What is Elgoglide®? Let’s use this simple formula to explain: PTFE fabric consisting of Teflon® and support fibers + resin matrix + adhesion/glue on the steel support body = Elgoglide®
The result is a balanced combination of high load capacity, excellent wear and friction behavior and excellent dry running characteristics
