The UKP series pillow block bearings consist of a sealed single-row ball bearing with a spherical outer ring which is mounted in a housing. Because of the spherical outer surface of the bearing, shaft misalignment can be compensated for. The bearings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with h-tolerances. The shaft is secured by grub screws on the inner ring.
The bearing insert consists of a solid spherical outer ring, an inner ring extended on both sides with conical bore as well as a cage; the plummer block housing (cast iron) is equipped with two slots for fixing. The cast iron offers an anti-corrosion protection by its passivated and lacquered surfaces, while the steel plate slingers on sides are for dust exclusion, full self alignment, grease fitting for adding lubricant. Regarding to the eccentric locking collar units, they provide locking for one-directional applications.
The pillow block bearing UKP series is suitable for high loads and speeds, also in case of alternating direction of rotation; misalignment can be equalized by spherical bearing seat.
Application
The pillow block bearings are widely applied to agriculture, automotive, pump, sporting and consumer goods, construction, manufacturing equipment, conveyor and fan assemblies, farm machinery, HVAC, feed mill, economical housed bearing solution and many other industrial equipment.
