Assembled Double Edge Ring System


The HepcoMotion double edge ring system with carriage may be used in either complete ring form or with segments. It can also be combined with straight slides to form a track system 40-44.


Rings may also be encircled by bearings either externally and/or internally with either ring or bearings being the moving element (see page opposite). The HepcoMotion PRT2 eccentric bearings are of double eccentric design with sufficient throw to enable disengagement of the carriage or encircled ring, without further disassembly.

Notes: 1. Two lengths of stud are available for each size of bearing 2. Offset holes in carriage for eccentric bearings necessitate adjustment in direction of arrow shown see


34-35. Choose according to required carriage thickness. 58.


3. Exact theoretical values have been given for 'Q', 'R' and 'S'. Positional accuracy of dimension 'S' will determine the axis of the ring. Positional accuracy for dimensions 'Q' and 'R' are not normally critical. Holes for bearing studs should be reamed to tolerance F6 for a sliding fit.
