Description

LINK-BELT PT3U223N is a pillow block bearing reference, within Bearing housings. Request a quote for PT3U223N via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

LINK-BELT PT3U series pillow block housings are mounted units with an incorporated bearing, designed to support rotating shafts in applications where the load is mainly radial and a fixed base with two mounting holes is required. They are used in transmission, conveying and process equipment, and allow the bearing to be aligned and protected in environments with dust, moisture or vibration. MR Accesorios Industriales sells this line as an official brand.

The PT3U designation is read in parts: PT indicates a pillow block housing with mounted bearing, 3 defines the housing type and U indicates that the insert is a single-row bearing with set screws for shaft fixing. The final number, as in PT3U212N or PT3U216N, corresponds to the nominal shaft diameter in inches according to the 200 series. The final letter N identifies a construction variant of the housing. With this data, the complete unit or the replacement insert can be selected.

These housings are used in belt conveyors, bucket elevators, mixers, mills, screens and process equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed, meatpacking and cement industries, where the environment demands a robust housing and sealing that retains lubrication. They are also used in fans, pumps and gear reducers that need a simple support that is easy to mount on metal or concrete structures.

To choose correctly, check the shaft diameter, the radial load and the load direction. Check the condition of the seal: the lips must be clean and free of cuts to prevent the entry of contaminants. During mounting, rest the housing on a flat, rigid surface, align the shaft with the equipment and tighten the insert set screws with the corresponding wrench. Lubricate according to the recommended grease type and check the axial and radial clearance before starting up.

Regarding equivalences, pillow block housings with a single-row insert and set screw fixing are interchangeable between different brands as long as the base dimensions, the center height and the shaft diameter match. To replace a LINK-BELT with another brand, compare those three values and the seal type. If you need an alternative, at MR Accesorios Industriales we will indicate the option compatible with your size.

To request a quote for the housing you need, send us the complete part number shown on the plate or on the part via WhatsApp, for example PT3U214N, and we will reply shortly. If you cannot find the exact variant, write to us with the shaft diameter and the working conditions: we will quote the unit or the insert that best suits your needs. MR Accesorios Industriales sells the LINK-BELT line and advises you so that the mounting is properly resolved.

Frequently Asked Questions

How do I identify the part number of the housing I need?
Look for the part number stamped on the housing or on the insert, such as PT3U212N. The letters PT indicate a pillow block housing, the 3 the housing type, the U the insert with set screws and the number the shaft diameter in inches. With that data we will quote it.
What is the difference between a PT3U housing and a flanged one?
The PT3U is a pillow block: it mounts on a flat base with two holes and supports radial loads. The flanged one has a circular housing with front holes for vertical mounting. The choice depends on the shaft position and the available space.
Can the insert be replaced without changing the whole housing?
Yes, if the housing is in good condition. The insert is the rotating part with the bearing and the set screws. To replace it, you need the same shaft diameter and fixing type. Ask us with the part number and we will quote the compatible insert.
