Ekspan J range of roller bearings are designed to allow movement whilst not inducing any significant friction into a structure. The roller itself is produced in a corrosion resistant material which is precision machined to ensure the correct finish is maintained. These can either be left exposed or encapsulated into a grease box to enable correct bearing functionality over a long duration. Roller bearings are no longer commonly found on many new build structures, however there are still a significant number of these bearings installed in current bridge stocks around the world. If you have a requirement for a roller bearing then please contact us with the relevant details so a bespoke solution can be provided.
