How the KR26 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 5.1 kN and C0 6.5 kN for the KR stud-type cam follower with needle roller and cage assembly; the C/C0 ratio of 0.78 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 0.86 kN at 10 mm stud, equivalent to 0.51 kN of dynamic rating per millimetre — the limiting speed is 8,000 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 0.14 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 The stud must be fully supported and torqued against a flat bracket face; an under-supported cantilever stud bends under the 6.5 kN static rating and skews the outer ring Typical applications include printing press sheet-transfer grippers, glass and ceramic line conveyors and cam drives and indexing tables, where the 26 mm track diameter and 5.1 kN dynamic rating match the duty. In printing press sheet-transfer grippers the threaded stud bolts directly to the frame, and in glass and ceramic line conveyors the 59 g mass keeps follower kinetics light. Designers also specify it for cam drives and indexing tables, relying on the 36 mm stud length and the published 6.5 kN static rating. Full-complement followers trade speed for static capacity — apply the lower limiting speed and expect higher drive torque than a caged KR. Never hammer the stud or use the hex socket as a press point during mounting; thread or socket damage renders the 36 mm stud unusable.

Selection pitfalls — read before you substitute

• Full-complement followers trade speed for static capacity — apply the lower limiting speed and expect higher drive torque than a caged KR.
• Never hammer the stud or use the hex socket as a press point during mounting; thread or socket damage renders the 36 mm stud unusable.
• On eccentric KRE/NUKRE/PWKRE units, re-torque after setting the collar — the adjustment changes the effective stud engagement.
