How the KRV22-PP model number is decoded

envelope 10×22×36 mm: the 22 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 6.2 kN and C0 9.3 kN for the KRV full-complement stud-type cam follower; the C/C0 ratio of 0.67 reflects a rolling-element pack sized for heavy static track loading, and the 6.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 1.23 kN at 10 mm stud, equivalent to 0.62 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 0.17 kN per millimetre of rolling-element complement within the 36 mm overall stud length mass is 45 g, or 0.06 g per mm² of the 22×36 mm track envelope — inertia that the drive must accelerate on every index of the cam at 10 mm stud shank this is one of the smallest HR1 executions — chosen where a 22 mm envelope must carry line-contact loads that no miniature ball bearing could take The standard stud axis fixes the roller centre; shimming the bracket faces is the way to adjust track preload The full complement raises static capacity but lowers the speed ceiling and generates more friction torque — slow, heavily loaded cams are its duty -PP means sealed both sides with elastomer lips — the roller is greased for life and needs no relubrication fitting in the 36 mm width. Typical applications include cam drives and indexing tables, printing press sheet-transfer grippers and woodworking machine feed tracks, where the 22 mm track diameter and 6.2 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 45 g mass keeps follower kinetics light. Designers also specify it for woodworking machine feed tracks, relying on the 36 mm stud length and the published 9.3 kN static rating. Use a washer under the nut and a flat square bracket face; the stud head alone cannot spread the clamp load of the heavy double-row executions. Sealed PP/2RS followers are life-lubricated; open KR/NUKR executions need the stud greaseway serviced on a fixed interval.

Selection pitfalls — read before you substitute

• Use a washer under the nut and a flat square bracket face; the stud head alone cannot spread the clamp load of the heavy double-row executions.
• Sealed PP/2RS followers are life-lubricated; open KR/NUKR executions need the stud greaseway serviced on a fixed interval.
• Full-complement followers trade speed for static capacity — apply the lower limiting speed and expect higher drive torque than a caged KR.
