Product summary
NATR 17 PPA: track roller, brand SKF. Bore diameter d 17 mm, outside diameter D 40 mm, width B 21 mm. Dynamic load rating C 10.5 kN, static load rating C0 14.6 kN, limiting speed 3400 rpm, weight 0.14 kg.
The thick-walled outer ring runs directly on a track or cam, no housing is needed. It carries radial load, often with a significant shock component.
Where it is used
Cam mechanisms and copying templates, linear guides, roller tables and conveyors, packaging and stamping machines, telescopic booms. Mounted on a stud or on an axle in a yoke, depending on the design.
When not to use
It does not replace an ordinary radial bearing fitted between shaft and housing: its load rating is calculated for the ring rolling on a track, not for uniform support around the whole circumference. The reverse swap is wrong too: the thin outer ring of an ordinary bearing run on a rail will be dented.
