igubal® pillow block bearing, mm/inch
Dimensional series K in mm and inch dimensions
igubal® pillow block bearings consist of a housing with a bearing insert. They are especially easy to install, compensate for misalignment, and prevent edge loads.
High tensile strength
Compensate for misalignment
Chemical and corrosion resistant
Suitable for rotational, oscillating, and linear motion
Can withstand high radial loads
Easy to install
The ability to pivot allows igubal® pillow block bearings to compensate for misalignment and possible shaft deflection. Applications in which these effects cannot be prevented are suited for igubal® pillow block bearings.
Maintenance-free igubal® pillow block bearings are designed with an inner diameter tolerance of E10. The shaft should be made to tolerance class h6 to h9. These recommended tolerances allow for changes in the bearing due to temperature and moisture absorption.
igubal® pillow block bearings are designed for mounting with two bolts. Precision mounting of the bearing is not necessary, since the spherical ball automatically compensates for misalignment.
igubal® pillow block bearings are available in the standard dimensions for shafts of 3/16" to 1" or 5 to 50 mm.
The load capacity of maintenance-free igubal® bearings is very high at normal ambient temperatures. igubal® bearings absorb high forces and weigh only one fifth of traditional, metal bearing housings. The excellent dampening properties are based on the fact that the plastic material of the two part bearing can absorb vibrations differently than steel.
However, plastic-specific properties, such a dependence on temperature and behavior under long-term stress, must be taken into consideration when using igubal® bearings. The load capacity of the pillow block should therefore be checked in a practical tests, particularly if it will be used under continuous high loads and at elevated temperatures.
