Direct replacement for GE5C spherical bearings. igubal® spherical bearings The use of spherical bearings is usually associated with high weight bearing materials, difficult installation, and high costs. Most of the time, maintenance is still necessary over the long-term, and the bearings are only corrosion-resistant in special designs. Often roller bearings or plain bearings malfunction prematurely due to high edge loads, or because they need to be elaborately readjusted, reamed, or refitted in order to compensate for alignment errors. igubal® spherical bearings put an end to all of these disadvantages and open up many new possibilities for your engineering design: they are easy to handle, cost-effective, lightweight and robust. The housing is made from igumid G, an extremely impact-resistant, long-fibre-reinforced polymer. Suitable for temperatures from -30 °C to +80 °C in long-term use. In standard spherical bearings, the spherical ball is made from iglidur® W300 material, which is known for lowest coefficients of friction in dry operation and extremely low tendency to stick-slip. This is especially important for low loads and very slow movements. Compensation of misalignment and edge loads Corrosion-resistant High vibration-dampening Excellent vibration dampening Suitable for rotating, oscillating and axial movements Tolerances Maintenance-free igubal® spherical bearings have a tolerance in the inner diameter of E10. The shaft tolerance should be between h6 and h9. The bearing clearance allows for expansion of the bearings due to increasing temperatures. Assembly igubal® spherical bearings are press-fitted into a recommended H7 housing bore and axially secured. Exact alignment of the bearing housing is not necessary since the spherical bearing automatically compensates for alignment errors.

CNC machined, precision milled and stress relieved cast aluminium plate with four slots (V2.4) and three counterbores (V1.8, Trident) to mount. The underside features two M3x0.5 threaded through holes for protective earth and temperature fuse. Chamfered from all sides. With our customized Keenovo Heatmat you get the best combination for your printer.

Miniature ball bearings are deep groove ball bearings in small. Their dimensions make them suitable for special applications. In addition, they allow very high speeds with low noise.
