1 22 ssembled Double Edge ing System

2 ssembled Double Edge ing System When using Hepcootion Double Edge ing Slides encircled by bearings as shown below it is recommended that two concentric bearings should be placed apart in order to provide a datum reference. The other bearings should be the eccentric type. ll eccentrics may be used where positional adjustment of the ring is required. One or more lubricators may be fitted at convenient positions to take advantage of the increased load/life afforded by lubrication T S Lubricator ing slides S U V W s Centre Lubricators FCC carriage L N O P S Positions *3 T U V W YZ BC 123 s Calculations Simply list the components required and if relevant, bracket those you wish to be factory Ordering details: assembled. 1 x ing segment Example: ssembled { 1 x FCC Fixed centre carriage

3 ssembled Single Edge ing System (External) When using Hepcootion external single edge ring slides it is recommended that two concentric bearings should be placed apart in order to provide a datum reference. The other bearings should be eccentric type. ll eccentrics may be used where positional adjustment of the ring is required. Either ring or bearings can be the moving element. The Hepcootion PT2 s are of double eccentric design with sufficient throw to enable disengagment of the ring without disassembly. One or more lubricators may be fitted at convenient positions to take advantage of the increased load/life afforded by lubrication E B Lubricator J K * 1 (min) F H G P D I C centre (max) L * 1 Section - ing Slide ef No For use with bearing (Ø) Positions *2 B C I J K *1 L *1 D E F G H ax in P EV J EV J ES J ES J ES 6...

Exact theoretical values have been given for `B`, `C` and `D`. Positional accuracy of dimension `B` will determine the axis of the ring. Positional accuracy for dimensions `C` and `D` are not normally critical. Holes for bearing studs should be reamed to tolerance F6 for a sliding fit. 24

4 ssembled Single Edge ing System (Internal) When using Hepcootion internal single edge ring slides it is recommended that two concentric bearings should be placed apart in order to provide a datum reference. The other bearings should be eccentric type. ll eccentrics can be used where positional adjustment of the ring is required. Either ring or bearings may be the moving element. The Hepcootion PT2 s are of double eccentric design with sufficient throw to enable disengagement of the ring, without further disassembly. One or more lubricators may be fitted at convenient positions to take advantage of the increased load/ life afforded by lubrication K *¹ (min) ing slides E B Lubricator J I C *3 D N F H G P s Lubricators Centre s (max) L*¹ Section - YZ BC 123 Calculations ing Slide ef No For use with bearing (Ø) Positions *3 I J K *1 L *1 B C D E F G H ax in N P IV J IV J IS 182 *3...

The eccentric blind hole fixing bearing cannot be used with the IS 182 ring slide as it clashes with the ring. 25
