How the KRV35-PP 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 12.6 kN and C0 23.4 kN for the KRV full-complement stud-type cam follower; the C/C0 ratio of 0.54 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 3.25 kN at 16 mm stud, equivalent to 0.79 kN of dynamic rating per millimetre — the limiting speed is 1,600 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 0.24 kN per millimetre of rolling-element complement within the 52 mm overall stud length mass is 166 g, or 0.09 g per mm² of the 35×52 mm track envelope — inertia that the drive must accelerate on every index of the cam the 16 mm stud shank falls in the small band, the workhorse size for gearbox planetary positions, hydraulic pumps and general cam and linkage duty The stud must be fully supported and torqued against a flat bracket face; an under-supported cantilever stud bends under the 23.4 kN static rating and skews the outer ring KRV is the full-complement stud-type cam follower: a cageless needle pack maximises C0 23.4 kN inside the 35 mm outer ring on the 16 mm stud The PP seals make this a maintenance-free unit: the 12.6 kN C rating is slightly below the open execution because the seal recesses shorten the effective roller complement. Typical applications include automatic assembly machine carriages, automotive welding jig rollers and linear rail and profile track guidance, where the 35 mm track diameter and 12.6 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 166 g mass keeps follower kinetics light. Designers also specify it for linear rail and profile track guidance, relying on the 52 mm stud length and the published 23.4 kN static rating. Sealed PP/2RS followers are life-lubricated; open KR/NUKR executions need the stud greaseway serviced on a fixed interval. 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.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Sealed PP/2RS followers are life-lubricated; open KR/NUKR executions need the stud greaseway serviced on a fixed interval.
• 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.
• 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.
