Product Description

SKF SY 40 TR Pillow Block Bearing featuring a robust cast iron housing combined with steel components, designed for industrial use requiring a 40 mm inside diameter and 49.2 mm centre height. This pillow block bearing supports shafts in rotary applications with dynamic and static load ratings of 30.7 kN and 19 kN respectively, ensuring reliable operation in demanding conditions.

The housing is constructed from cast iron, which imparts high compression strength and excellent abrasion resistance, making it suited for long-term use in harsh environments. The bearing unit is pre-greased to reduce installation time and includes a relubrication hole for easy maintenance, promoting continuous smooth rotation at speeds up to 2800 rpm.

It features boltholes on the housing for straightforward mounting on machine frames or conveyors. Seals and flingers on both sides prevent intrusion of dirt and contaminants, extending service life. The bearing’s inner ring extends beyond the housing, providing enhanced support for the shaft under dynamic loads, and the locking type uses set screws to secure the assembly firmly.

This pillow block bearing has a cylindrical bore type and an open end design, with dimensions including length 203 mm, depth 48 mm, height 99 mm, and bolt hole size 14 mm among other key measurements, ensuring compatibility with standard mounting systems.

Applications include use in HVAC systems, agricultural and waste management machinery, assembly lines, conveyors, and cranes where reliable shaft support and vibration damping are critical.

The housing has cast iron construction providing strength and resistance to wear. The bearing is pre-lubricated with grease for immediate use and longer service intervals. Seals on both sides protect against contaminants ensuring clean operation.

Mounting holes simplify secure installation on various surfaces. Locking set screws secure the bearing on the shaft preventing slippage under load.

This SKF SY 40 TR pillow block bearing is manufactured in Italy to high-quality standards and is ideal for industrial, agricultural, and HVAC applications requiring dependable shaft support.
