SY35TF SKF 2 Bolt Plummer Block Y Bearing with Grub Screws 35mm

The SKF SY35TF is a premium-quality pillow block ball bearing unit designed to provide dependable shaft support in industrial machinery, agricultural equipment, conveyor systems, and material handling applications. Supplied as a complete ready-to-install assembly, the unit combines the SKF YAR 207-2F insert bearing with the heavy-duty SY 507 M cast iron housing, providing excellent load carrying capability, effective sealing protection, and extended service life.

Designed for 35mm shaft diameters, the SY35TF features an extended inner ring with a dual set screw locking arrangement, ensuring secure shaft location and reliable operation under vibration, shock loads, and varying operating conditions. Suitable for both continuous and reversing shaft rotation, the unit offers a versatile and cost-effective mounting solution across a wide range of industrial applications.

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

Manufactured from high-grade bearing steel and housed within a rugged cast iron pillow block, the SY35TF incorporates SKF's proven self-aligning design, enabling compensation for minor shaft misalignment and mounting inaccuracies while maintaining smooth, efficient operation.
