SKF 4 Hole Cylindrical, FY 50 TR 50 mm ID

This flange bearing unit is a square 4‑bolt housed ball bearing designed for material‑handling and industrial shaft‑support applications. It combines a cast‑iron housing with multiple sealing elements and an open‑ended bearing to permit routine relubrication, offering a Compact mounted solution for rotating shafts with a cylindrical bore.

• 35.1 kN dynamic rating gives high load capacity for moving loads
• 23.2 kN static rating resists heavy static forces during stoppage
• 2,200 rev/min limiting speed suits medium‑speed driven equipment
• Steel set‑screw locking secures the shaft for straightforward mounting
• 60.6mm housing width supports stable alignment under load

• Suitable for conveyor drive shafts in automated lines
• Ideal for motor and gearbox output shaft support
• Used for bearing supports in packaging machinery
• Can be used for pivot supports in handling systems

The unit includes a grease fitting compatible with standard grease guns and a 1/4‑28 SAE‑LT threaded lubrication port for replenishment without disassembly.

The housing mounts with four bolts through 18mm holes and a 111mm centre‑to‑centre bolt pattern, enabling a robust flange attachment to frames or plates.

It accepts a cylindrical 50mm shaft bore and is specified for use with shafts manufactured to h6 tolerance for correct fit and rotational performance.

Multiple Seals are fitted to limit ingress of contaminants while permitting relubrication via the grease fitting, balancing protection with maintenance access.
