How the KR-35-B model number is decoded

the 35 mm outside diameter runs on the track while the 16 mm stud shank takes the pin or shaft; the 52 mm overall width spreads the Hertzian contact over the outer ring published ratings C 9.52 kN and C0 13.7 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.69 is typical for cam follower with needle roller and cage executions fatigue load limit Pu 1.56 kN at 16 mm stud gives a specific load of 0.59 kN per mm; the limiting speed is 4,000 r/min the 52 mm width carries the load at 0.18 kN per mm of roller complement; section height 9.5 mm between stud and track surface determines the outer-ring bending stiffness mass 170 g over a 35x52 mm envelope works out to 0.093 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty the 16 mm stud diameter falls in the small-size band, the most common choice for general-purpose cam followers and light conveyor transfer rollers the KR designation means the standard cam follower execution — cage-guided needle rollers for low friction, a threaded stud for direct bracket mounting, and a cylindrical outer ring for track contact B on this KR designation indicates a double-ended hexagonal stud — the larger head accommodates a standard hex key for secure tightening typical applications include automotive welding jig positioners, conveyor transfer and diverting rollers and woodworking machinery feed rollers this size is commonly specified for automotive welding jig positioners and conveyor transfer and diverting rollers, where the 35 mm track diameter and 16 mm stud fit standard cam and rail geometries in woodworking machinery feed rollers the 35 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 170 g mass is low enough for rapid indexing cycles the stud head is relatively small; use a washer under the nut to spread the clamping load and prevent bracket surface damage the open design has no integral sealing; in dusty environments contamination enters directly between the needle rollers and the raceway

Selection pitfalls — read before you substitute

• the single-row needle complement is the lightest cam follower option; do not overload it beyond the printed C rating
• the stud head is relatively small; use a washer under the nut to spread the clamping load and prevent bracket surface damage
• the open design has no integral sealing; in dusty environments contamination enters directly between the needle rollers and the raceway
