PRT ring slides and track system GV3 linear guidance and transmission system This data sheet interacts with PRT & GV3 Catalogues Floating Bearings HepcoMotion® Floating Bearings are designed to provide axial movement (float) of the V position, this is especially useful where two rings or V slides are mounted in parallel. The axial movement compensates for parallelism tolerances between the opposing V’s, reducing the potential of additional loading and helping to maintain a consistent running quality. The floating bearings are available in three basic sizes to work easily with the existing GV3 and PRT ranges. They are available in two stud lengths covering most thicknesses of carriage or mounting plate, the short stud version being compatible with Hepco carriage plates*6. Both versions are available in Concentric type (C), which are fixed providing a datum (in radial direction) for the system, Eccentric (E) and Double Eccentric type (DE) to enable system adjustment, with the DE version having sufficient stroke to permit disengagement of a ring encircled by bearings. All bearings are greased for life internally. Customers are strongly advised to provide lubrication to the interface between the bearings and slide to increase load capacity and life. Details of the floating bearings are included in this datasheet. For more information or to suit a specific application please contact Hepco’s Technical Department. Nitrile Seals • Seal against the ingress of debris Caged Needle Roller Bearings • Allows high speeds and lubrication for life Floating bearings can be used when two track systems are mounted in parallel. The bearing is designed to ‘float’ so as to accommodate parallelism tolerances

Short stud (SFJ) / Long stud (LFJ) 1. It is recommended that holes to suit bearing mounting studs should be reamed to tolerance F6 for a sliding fit. 2. The quoted static and dynamic load capacities use industry standard calculations and are only provided for comparison with other systems. Please use the Max Working Load figures, and the calculation methods from the Hepco GV3 catalogue, 58-61. In all cases, Hepco floating bearings will have a life as long or longer than the corresponding size of Hepco V bearings. 3. The 'N' dimension is both the eccentric offset of the adjusting nut and the...
