This NSK UKF flange housing with insert bearing is a 4-bolt mounted unit consisting of a cast iron housing and a UK series insert bearing. It supports shafts where front mounting with high rigidity is required and where the shaft is unmachined. It is commonly used in light and medium power transmissions and is available in metric and inch sizes depending on the code.

The UKF code denotes a 4-bolt square flange housing with a tapered bore insert bearing that is secured to the shaft using an adapter sleeve. The digits that follow indicate the insert series and size: UKF211 uses a series 2 insert, while UKF311 uses a series 3 insert with a heavier housing for the same shaft size. The D1 suffix identifies the insert variant. The next code, such as HE2311XY, is the adapter sleeve for mounting: HE is for inch shafts and H for metric shafts. This setup allows the bearing to be fixed on a plain shaft without a shoulder or extra nut.

Typical applications include belt conveyors, mixers, chain elevators, blowers, and packaging lines. They are also found in food plants, cement plants, ceramics, and metalworking shops where a flange unit must handle radial load and some axial load. Irrigation equipment and agricultural machinery also use them, provided the shaft is the correct size and the flange sits on a flat, rigid surface.

When selecting, start with the shaft diameter and adapter sleeve: the same UKF housing is used with an H sleeve on metric shafts or an HE sleeve on inch shafts, always on plain shafts. Check the insert sealing for the working environment, especially with dust or moisture. During mounting, align the flange with the shaft and tighten the bolts in a cross pattern to prevent housing distortion. Tighten the sleeve following the manufacturer's procedure and lubricate the insert according to the operating conditions.

Interchangeability between brands is based on shaft size, sleeve, and flange type: a UKF from another brand with the same size and bolt hole pattern has an NSK equivalent. Compare shaft diameter, bolt hole spacing, and sleeve type. At MR Industrial Accessories we quote the exact code or the size you need: send the model by WhatsApp or email and we will respond promptly.
