DRAFT - INTERNAL USE ONLY DRAFT - INTERNAL USE ONLY This data sheet interacts with PRT & GV3 Catalogues GV3 LINEAR GUIDANCE AND TRANSMISSION SYSTEM HepcoMotion.com Filename: GV3 14.1 UK 2023 Last saved: 16 January 2024 9:58 am Filename: GV3 14.1 UK 2023 Last saved: 16 January 2024 9:58 am Last saved: 16 January 2024 9:58 am 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 Standard bearings Floati

Short stud (SFJ) / Long stud (LFJ) For use with Part Number Max Working Load Capacity SFJ..C/E/DE LFJ..C/E/DE Adjusting Socket Tool Wrench Bearing Static (Co) and Dynamic (C) Radial Load Capacities (N)*2 Part Number Notes: 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, 50 - 52. In all...
