SY65TF SKF 2 Bolt Plummer Block Y Bearing with Grub Screws 65mm

The SKF SY65TF is a heavy-duty pillow block ball bearing unit engineered for reliable shaft support in demanding industrial, agricultural, quarrying, processing, and material handling applications. Supplied as a complete ready-to-install assembly, the unit combines the SKF YAR 213-2F insert bearing with the robust SY 513 M cast iron housing, providing exceptional load carrying capability, effective sealing performance, and long-term operational reliability.

Designed for 65mm shaft diameters, the SY65TF features an extended inner ring with dual set screw locking, ensuring secure shaft retention in applications exposed to vibration, shock loads, and varying operating conditions. Suitable for both continuous and reversing shaft rotation, the unit offers a dependable and versatile mounting solution across a broad range of industrial 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, moisture, and other contaminants. A relubrication facility with grease nipple is supplied as standard, allowing routine maintenance and helping maximise bearing service life while reducing downtime and maintenance costs.

Manufactured from premium-grade bearing steel and housed within a rugged cast iron pillow block housing, the SY65TF incorporates SKF's proven self-aligning design, enabling the unit to compensate for minor shaft misalignment and mounting inaccuracies while maintaining smooth and efficient operation under demanding working conditions.
