Allowable loading capacity of cast iron housing

FK cast iron housing is produced by high quality HT20o material,and designed to met insert bearing loading capacity However, housing strength must be taken into consideration under low speed heavy load or impact load and other special application.

5.1 Destruction strength of cast iron housing

FK housing lab gets following data by many years research and test, This is the average destruction strength under static loading, so +30% deviation must be considered, Cast iron housing has many good properties, but it is fragile under impact load, so safety factor must be considered.

5.2 Allowabale Load of Pressed Housings

Pressed housing shows deformation when subjected to heavy load. The deformation depends upondireclion and amount of the load, form of the housing and thickness of steel plate, Therefore, the allowableload of the pressed housing must be such an amount that deformation of the housing may not disturbedthe function.

The allowable radial load of pressed housing is approximately 1/6 of the bearing basic dynamic loadraing (Cr), and allowable axial load of pressed housing is approximately 1/18 of the bearing basic dynamicload rating (Cr).

2025 September 2nd Week FK Product Recommendation:

Flange Cartridge Units:

They are units of rigid cast iron housings with piloted flange cartridge and wider inner ring bearing inserts.

Standard painting in green (other colors are available for choices).

Standard duty (FC200) and medium duty (FCX) are available for this series.

End caps by pressed steel are capable of protecting against external polution and dusts.

The self-aligning ability of the ball bearings can compensate for slight static mis-alignemnt of the shaft. The bearing inserts are locked onto the shaft by means of set screws, eccentric locking collars, adapter sleeves and concentric locking collars etc.

Lubricants filled inside the spherical ball bearing inserts can be standard grease, low/hight temperature grease and food grade grease.
