Cast Iron

The SFR (cast iron) and SSFR (Steel) ranges of wheel assemblies have been designed to fit within standard sections of channel and ´I´ beams. The radiused tread accommodates the angle of the section and improves the wear and tracking characteristics.
MATERIAL: SFR series - Cast iron to BS1452: 1977: Grade 200
SSFR series - Steel to BS970: Part 1: 1983: 080M40
Axles - Steel to BS970: Part 1: 1983: 606M36 or 605M36
SFR (cast iron) wheels are not suitable where substantial shock loads are to be withstood, and they have a limited service life in comparison with the equivalent SSFR wheel.
When shock loadings are to be withstood by either the SFR or SSFR ranges the ´maximum load rating´ should be reduced by multiplying by a shock loading factor of 0.65.
