The SKF FYTWK 504 NY is a Y-bearing unit that pairs a cast iron housing with an insert bearing locked by set screws. It holds a rotating shaft on a fixed structure, keeping the transmission line supported and aligned. Maintenance crews use it where rotation must run smoothly and service stays simple.
Reading the code helps you match a replacement. FYT identifies the foot-mounted housing that carries the insert bearing. The W marks a housing shape with ribs or reinforcements. K tells you the insert locks with set screws, and 504 is the size code that sets the shaft diameter and the main dimensions. NY covers the seal type and insert design. FYTWK 504 NY fits 1 1/4 inch shafts; other numbers in the series cover other sizes.
Typical duty includes belt conveyors, bucket elevators, mixers, fans and agricultural equipment, and the unit is a frequent replacement item in maintenance work. Because it mounts on a foot, it sits on profiles or flat bases, and the set screw insert adjusts on the shaft without complex machining.
For selection, confirm the shaft diameter and the base dimensions. The NY seal keeps out dust and splashes, though it is not a substitute for a radial shaft seal where immersion occurs. During mounting, line the housing up with the shaft and tighten the set screws onto the insert inner ring; misalignment speeds up wear. Lubricate per the insert type and verify radial clearance. Add fastening where vibration is present.
Interchangeability deserves care. Y-bearing housings with insert bearings from different brands often share standardized dimensions, but check base dimensions and shaft diameter before replacing. The SKF FYTWK series may have equivalents elsewhere, yet suffixes and locking systems differ. A similar code from another company is not automatically the same part, so compare drawings or ask us. MR Industrial Accessories can help you identify the correct unit.

Frequently asked questions
- What does the FYTWK 504 NY code mean?
- FYT is the foot-mounted housing with insert bearing; W is a special housing shape; K is set screw locking; 504 is the size for a 1 1/4 inch shaft; NY is the sealing type and insert design. Each part describes one feature of the assembly.
- Can this housing handle dusty or humid areas?
- The NY seal guards against dust and splashes, which suits moderately contaminated industrial settings. Where water sprays directly or immersion is possible, review a more tightly sealed option or ask our team to pick the right variant.
- How does the insert bearing go onto the shaft?
- Set the housing aligned on its base, slide the shaft in, then tighten the set screws onto the inner ring of the insert bearing. Check alignment and radial clearance before start-up, and follow the manufacturer's tightening torque.
