Series QD plain bearing, Tread with gradient 3°

Technical Specifications
- Flanged wheels: moulded grey cast iron.
- Temperature range: -30°C to +600°C

Characteristics
These flanged wheels are made of moulded grey cast iron. The final dimensions are machined as well as the 3° tread ascent to the axle. The blue lacquer coating provides protection against environmental influences. The wheels are very highly sideways- and peak load resistant and have a plain bore. Temperature range from -30°C to +120°C. In case of heat resistant use (with plain bore) from -30°C to +600°C.
Rule of thumb at use on maximum temperature: Load capacity= ½ of indicated load capacity.
The cast iron flanged wheels have a very high load capacity and yet an extremely low rolling resistance, especially the ball bearing type. They are extremely wear- and shock resistant and insensitive to sharp materials. A higher noise level is to be considered. At regular exposure to high temperatures, frequently bearing-lubrication with high-temperature grease is recommended.

Applications
Heavier loads on rails or other profiles, possibly filthy with sharp materials like glass or metal curls, where low requirements are made to noise and rolling comfort, but low rolling resistance is required.
