The SKF SYKC ATR/VZ housing is an assembly made up of a cast iron housing and a Y-bearing insert with set screw locking, ready to mount on shafts and structures. It is used to guide rotating shafts in transmission and conveying equipment, where a compact, self-aligning unit is required. MR Accesorios Industriales supplies this line, with advice to choose the correct variant according to shaft diameter and locking type.

The designation SYKC ATR/VZ is read in parts: SYKC identifies the category of Y-bearing units with set screw locking; ATR indicates that the insert has an outer ring with groove and relubrication hole, and VZ corresponds to the contact lip seal. The number in the middle, as in SYKC 1.1/4 ATR/VZ393, indicates the shaft diameter in inches, in this case 1.1/4". The final three-digit suffix refers to a specific construction variant within the series.

These units are found in belt conveyors, bucket elevators, mixers, screens and packaging lines. In Argentina they are common in food, cement, mining and aggregate processing plants, where dust and moisture demand reliable sealing. They also appear in irrigation equipment, mills and agricultural machinery, provided the shaft rotates at moderate speeds and loads are predominantly radial.

To select correctly, check the shaft diameter and locking type: set screws work well on shafts with little torque, but if there are axial loads or reversals, an insert with adapter sleeve is better. Check the VZ seal: a contact lip retains grease better and blocks contaminants. During mounting, support the housing on a flat, rigid surface, align both shaft supports and tighten the set screws on the inner ring, never on the outer. Relubricate according to the working environment.

Y-bearing units are interchangeable between brands if shaft diameter, locking type and mounting dimensions match. Each manufacturer uses its own suffixes for sealing and variants, so do not rely on the code alone: compare mounting surface, hole spacing and center height. If you have the old code, send it and we will cross-reference it with the equivalent alternative.
