How the NUKRE35 model number is decoded

envelope 16×35×52 mm: the 35 mm outside diameter is the track-running surface — a thick-walled outer ring over a 16 mm stud — and the 52 mm overall stud-and-roller length sets the required bracket clearance the catalogue lists C 15.3 kN and C0 19 kN for the NUKRE double-row full-complement stud-type track roller with eccentric locking collar; the C/C0 ratio of 0.81 reflects a rolling-element pack sized for heavy static track loading, and the 9.5 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 2.48 kN at 16 mm stud, equivalent to 0.96 kN of dynamic rating per millimetre — the limiting speed is 6,500 r/min and, as for HR1 track rollers, no thermal reference speed is published the 16 mm threaded stud clamps directly into the machine bracket; over the roller running width the dynamic rating works out to 0.29 kN per millimetre of rolling-element complement within the 52 mm overall stud length mass is 177 g, or 0.10 g per mm² of the 35×52 mm track envelope — inertia that the drive must accelerate on every index of the cam with a 16 mm stud shank the 52 mm width and 15.3 kN C rating suit high-cycle industrial machinery rather than instrument duty The outer ring is axially guided by the rolling elements against the stud head and thrust washer; the clamping faces must be square so the 177 g roller runs without cantilever bending NUKRE is a double-row full-complement stud-type track roller: two cylindrical roller rows run on a heavy-section threaded stud, ready to bolt straight into a bracket Typical applications include cam drives and indexing tables, printing press sheet-transfer grippers and woodworking machine feed tracks, where the 35 mm track diameter and 15.3 kN dynamic rating match the duty. In cam drives and indexing tables the threaded stud bolts directly to the frame, and in printing press sheet-transfer grippers the 177 g mass keeps follower kinetics light. Designers also specify it for woodworking machine feed tracks, relying on the 52 mm stud length and the published 19 kN static rating. Never hammer the stud or use the hex socket as a press point during mounting; thread or socket damage renders the 52 mm stud unusable. Sealed PP/2RS followers are life-lubricated; open KR/NUKR executions need the stud greaseway serviced on a fixed interval.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Never hammer the stud or use the hex socket as a press point during mounting; thread or socket damage renders the 52 mm stud unusable.
• Sealed PP/2RS followers are life-lubricated; open KR/NUKR executions need the stud greaseway serviced on a fixed interval.
• 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.
