How the KRV26-PP model number is decoded

envelope 10×26×36 mm: the 26 mm outside diameter is the track-running surface — a thick-walled outer ring over a 10 mm stud — and the 36 mm overall stud-and-roller length sets the required bracket clearance the catalogue lists C 7.3 kN and C0 11.6 kN for the KRV full-complement stud-type cam follower; the C/C0 ratio of 0.63 reflects a rolling-element pack sized for heavy static track loading, and the 8.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 1.52 kN at 10 mm stud, equivalent to 0.73 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 10 mm threaded stud clamps directly into the machine bracket; over the roller running width the dynamic rating works out to 0.20 kN per millimetre of rolling-element complement within the 36 mm overall stud length mass is 59 g, or 0.06 g per mm² of the 26×36 mm track envelope — inertia that the drive must accelerate on every index of the cam 10 mm stud shank and only 59 g: the smallest sizes demand accurate shaft geometry, because the 8.0 mm section leaves no tolerance for a soft or tapered seat C 7.3 kN, C0 11.6 kN and Cur 1.52 kN are the cam-contact ratings; the limiting speed is 2,600 r/min with no reference speed published The full complement raises static capacity but lowers the speed ceiling and generates more friction torque — slow, heavily loaded cams are its duty -PP protection suits cams and rails that are washed down or run in dust; exceeding the 2,600 r/min speed ceiling overheats the lips rather than just accelerating wear. Typical applications include linear rail and profile track guidance, automatic assembly machine carriages and glass and ceramic line conveyors, where the 26 mm track diameter and 7.3 kN dynamic rating match the duty. In linear rail and profile track guidance the threaded stud bolts directly to the frame, and in automatic assembly machine carriages the 59 g mass keeps follower kinetics light. Designers also specify it for glass and ceramic line conveyors, relying on the 36 mm stud length and the published 11.6 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. On eccentric KRE/NUKRE/PWKRE units, re-torque after setting the collar — the adjustment changes the effective stud engagement.

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.
• On eccentric KRE/NUKRE/PWKRE units, re-torque after setting the collar — the adjustment changes the effective stud engagement.
• Sealed PP/2RS followers are life-lubricated; open KR/NUKR executions need the stud greaseway serviced on a fixed interval.
