Product Description

When using RunFine Bearing Housing Units UKF300+H series, the customer enjoys the following benefits:

There is no risk of breakdown costs which otherwise cannot be excluded with installation by the customer.

At RunFine's, the bearings are mounted in a cleanroom under optimum conditions.
Depending on the customer's requirements, other functional elements may be integrated in the Bearing Units, for example springs and seals.

4 Bolt Flange Unit UKF300H Series

The RunFine 4 Bolt Flange Unit UKF300H Series is a combination of a radial Ball Bearing, seal, and a housing of high-grade cast iron or pressed steel, which comes in various shapes. The outer surface of the bearing and the internal surface of the housing are spherical, so that the unit is self-aligning.

The inside construction of the ball bearing for the unit is such that steel balls and retainers of the same type as in series 62 and 63 of the Deep Groove Ball Bearing are used. A duplex seal consisting of a combination of an oil-proof synthetic rubber seal and a slinger is provided on both sides.

RunFine joins the components in Bearing Units UKF300+H series primarily by gluing. Gluing of bearings under axial preload is a cost-effective way of providing for reduction of play. RunFine has developed special gluing equipment and technologies to ensure high accuracy and stiffness.
