NUKR – NUKRE – PWKR – PWKRE SERIES
Peculiar characteristics of the Stud Type rollers are, in addition to those already indicated, a partly threaded and partly grinded extreme part of the pin in order to center itself in the seat during assembly;
On one extremity, an integral edge and cemented and tempered roller track;
On both extremities of the pin in the front position there are hexagonal seats for assembly.
On request they can be supplied with cylindrical outer ring diameter (suff. X) and also with an eccentric bushing (suff. E) centred on the grinded pin end part, which allows a certain degree of adjustment. They can be supplied with watertight sealing rings;
In this case the holes for relubrication can be closed by special forced plugs.
