capacity are particularly suitable for oscillating motion with heavy loads. The stable, moisture-resistant connection between the sliding layer and the support body has been a successful solution for many years now. The sliding material does not swell, does not fuse with metal and is largely chemically resistant.

• Maintenance free and environmentally friendly • Small dimensions, high performance • Easy to install, little space required • Individual design based on customer requirements

need for lubrication. Our low-friction dry plain bearings with high load-supporting

Axial Piston pumps in swash plate design The inclined drive pulley and the swash plate are firmly attached to the drive shaft while the cylinder block is stationary. The thrust bearings transmit the high forces from the pistons that act in the direction of the stroke. Out of balance and radial forces are supported by stable, speed-optimized cylindrical Roller bearings. Favorable bearing technology through • Smooth and low-friction operation even with extremely high loads • Good static and dynamic load ratings

Axial piston pumps with adjustable cradle INA bearings provide support for the precise operation of Excavators or road Construction equipment with highly accurate positioning and constantly changing strength ratios. Full-complement or nearly fullcomplement Cylindrical roller bearings allow precise settings for the flow rate, even at high pressures. Components such as bearing segments, pressure pads and steel Seals are also preferred choices. Ground inner rings without spiral marks and with extremely wearresistant ceramic coating minimize leakage and abrasion.
