How the RSTO5-TV model number is decoded

envelope 7×16×7.8 mm: the 16 mm outside diameter is the track-running surface — a thick-walled outer ring over a 7 mm bore — and the 7.8 mm width sets the contact width on the mating track the catalogue lists C 2.55 kN and C0 2.65 kN for the RSTO yoke-type track roller without inner ring, without axial guidance; the C/C0 ratio of 0.96 reflects a rolling-element pack sized for heavy static track loading, and the 4.5 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 0.335 kN at 7 mm bore, equivalent to 0.36 kN of dynamic rating per millimetre — the limiting speed is 16,000 r/min and, as for HR1 track rollers, no thermal reference speed is published the 7 mm bore takes the mounting pin or shaft; across the 7.8 mm contact width the dynamic rating works out to 0.33 kN per millimetre of rolling-element complement mass is 8.5 g, or 0.07 g per mm² of the 16×7.8 mm track envelope — inertia that the drive must accelerate on every index of the cam 7 mm pin bore and only 8.5 g: the smallest sizes demand accurate shaft geometry, because the 4.5 mm section leaves no tolerance for a soft or tapered seat At 8.5 g the roller adds little inertia to follower linkages, but the unflanged design walks off a skewed track — track parallelism substitutes for the missing guidance Reading RSTO: yoke roller, no inner ring, no flanges; lateral guidance and contamination protection must come from the machine structure around the 7.8 mm-wide roller With the -TV polyamide cage the rollers are positively separated, so the 7 mm bearing suits continuous rotation rather than the slow oscillating duty where cageless packs are chosen. Typical applications include cam drives and indexing tables, printing press sheet-transfer grippers and woodworking machine feed tracks, where the 16 mm track diameter and 2.55 kN dynamic rating match the duty. In cam drives and indexing tables the unit fits a compact 7 mm seat, and in printing press sheet-transfer grippers the 8.5 g mass keeps follower kinetics light. Designers also specify it for woodworking machine feed tracks, relying on the 7.8 mm width and the published 2.65 kN static rating. The pin or shaft is part of the bearing system: harden it for RSTO/RNA22 positions, and size its deflection because the roller cannot compensate for a bent pin. Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam.

Selection pitfalls — read before you substitute

• The pin or shaft is part of the bearing system: harden it for RSTO/RNA22 positions, and size its deflection because the roller cannot compensate for a bent pin.
• Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam.
• Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.
