How the NUKRE62 model number is decoded

envelope 24×62×80 mm: the 62 mm outside diameter is the track-running surface — a thick-walled outer ring over a 24 mm stud — and the 80 mm overall stud-and-roller length sets the required bracket clearance the catalogue lists C 40.5 kN and C0 55 kN for the NUKRE double-row full-complement stud-type track roller with eccentric locking collar; the C/C0 ratio of 0.74 reflects a rolling-element pack sized for heavy static track loading, and the 19.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 7.4 kN at 24 mm stud, equivalent to 1.69 kN of dynamic rating per millimetre — the limiting speed is 2,600 r/min and, as for HR1 track rollers, no thermal reference speed is published the 24 mm threaded stud clamps directly into the machine bracket; over the roller running width the dynamic rating works out to 0.51 kN per millimetre of rolling-element complement within the 80 mm overall stud length mass is 824 g, or 0.17 g per mm² of the 62×80 mm track envelope — inertia that the drive must accelerate on every index of the cam with a 24 mm stud shank the 80 mm width and 40.5 kN C rating suit high-cycle industrial machinery rather than instrument duty Stud mounting puts all moment load into the bracket — torque the stud nut to the catalogue value, support the shank over its full length, and use the eccentric collar only for its small design adjustment range Two cageless roller rows deliver C 40.5 kN and C0 55 kN, 1.69 kN of dynamic rating per millimetre of stud — the heaviest track-roller ratings in the HR1 range Typical applications include automatic assembly machine carriages, automotive welding jig rollers and linear rail and profile track guidance, where the 62 mm track diameter and 40.5 kN dynamic rating match the duty. In automatic assembly machine carriages the threaded stud bolts directly to the frame, and in automotive welding jig rollers the 824 g mass keeps follower kinetics light. Designers also specify it for linear rail and profile track guidance, relying on the 80 mm stud length and the published 55 kN static rating. The stud must be fully supported and the nut torqued to the catalogue value; a loose follower wears the bracket hole oval and loosens further. Never hammer the stud or use the hex socket as a press point during mounting; thread or socket damage renders the 80 mm stud unusable.

Selection pitfalls — read before you substitute

• The stud must be fully supported and the nut torqued to the catalogue value; a loose follower wears the bracket hole oval and loosens further.
• Never hammer the stud or use the hex socket as a press point during mounting; thread or socket damage renders the 80 mm stud unusable.
• On eccentric KRE/NUKRE/PWKRE units, re-torque after setting the collar — the adjustment changes the effective stud engagement.
