How the PWKRE62-2RS-XL model number is decoded

envelope 24×62×80 mm: the 62 mm outside diameter is the track-running surface — a thick-walled outer ring over a 24 mm stud — and the 80 mm overall stud-and-roller length sets the required bracket clearance the catalogue lists C 35 kN and C0 46 kN for the PWKRE sealed double-row full-complement stud-type track roller with eccentric locking collar; the C/C0 ratio of 0.76 reflects a rolling-element pack sized for heavy static track loading, and the 19.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 5.9 kN at 24 mm stud, equivalent to 1.46 kN of dynamic rating per millimetre — the limiting speed is 2,200 r/min and, as for HR1 track rollers, no thermal reference speed is published the 24 mm threaded stud clamps directly into the machine bracket; over the roller running width the dynamic rating works out to 0.44 kN per millimetre of rolling-element complement within the 80 mm overall stud length mass is 824 g, or 0.17 g per mm² of the 62×80 mm track envelope — inertia that the drive must accelerate on every index of the cam with a 24 mm stud shank the 80 mm width and 35 kN C rating suit high-cycle industrial machinery rather than instrument duty The stud is drilled for relubrication via the lubricating nipple in the head; the limiting speed is 2,200 r/min and no thermal reference speed is given for track rollers The -XL suffix marks the X-life execution: refined raceway topography and upgraded materials lift the basic ratings versus the non-X-life bearing at the same 24×62×80 mm envelope. With 2RS seals the 824 g roller is effectively sealed for life — no relubrication path is provided and none is needed over the design life. Typical applications include woodworking machine feed tracks, cam drives and indexing tables and packaging machine timing mechanisms, where the 62 mm track diameter and 35 kN dynamic rating match the duty. In woodworking machine feed tracks the threaded stud bolts directly to the frame, and in cam drives and indexing tables the 824 g mass keeps follower kinetics light. Designers also specify it for packaging machine timing mechanisms, relying on the 80 mm stud length and the published 46 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. 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.

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.
• 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.
• The eccentric collar throw is small (typically around 1 mm); it removes clearance, it cannot repair a grossly misplaced bracket.
