Product summary

305804 C 2Z: track roller, brand SKF. Bore diameter d 20 mm, outside diameter D 52 mm, width B 20.6 mm. Seal: metal on both sides. Dynamic load rating C 19 kN, static load rating C0 12 kN, limiting speed 7000 rpm, weight 0.22 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.
