SY30TF SKF 2 Bolt Plummer Block Y Bearing with Grub Screws 30mm

The SKF SY30TF is a robust pillow block ball bearing unit designed to provide dependable shaft support in demanding industrial, agricultural, and material handling applications. Supplied as a complete ready-to-install assembly, the unit combines the SKF YAR 206-2F insert bearing with the heavy-duty SY 506 M cast iron housing, delivering excellent load carrying capability, reliable sealing performance, and long operational life.

Designed for 30mm shaft diameters, the SY30TF incorporates an extended inner ring with dual set screw locking, ensuring secure shaft location and resistance to vibration and shock loads. Suitable for both continuous and reversing shaft rotation, the unit offers a versatile mounting solution across a wide range of machinery and equipment.

The bearing insert is factory lubricated and protected by contact seals and steel flingers on both sides, helping to retain lubricant while preventing the ingress of dust, dirt, and moisture. A relubrication facility with grease nipple is provided as standard, allowing routine maintenance and helping maximise bearing service life.

Manufactured from high-quality bearing steel and housed within a rugged cast iron pillow block, the SY30TF features SKF's proven self-aligning design, enabling compensation for minor shaft misalignment and mounting inaccuracies while maintaining smooth and efficient operation.
