SKF extend JIS-compliant ball bearing unit range

SKF ball bearing unit

New UC 300 series for increased protection against contamination in heavy-duty applications

SKF have extended their UC range of ball bearing units with the launch of new UC 300 series units, which are available on short lead times, feature superior sealing and stronger locking, and are interchangeable with all JIS (Japanese Industrial Standards) housings.

The new UC 300 series units are designed for use in highly contaminated industrial environments where bearing life can often be shortened through the ingress of process materials such as mud, dust or water.

To overcome these problems, the UC 300 series is equipped with field-proven sealing technology. Units also have a solid-base housing to minimize areas that might otherwise trap dirt or moisture.

When bearings are subject to systemic vibration, the results can include increased shaft imbalance, misalignment and loosening of locking mechanisms. The UC 300 series is said to addresses all these problems thanks to its robust construction and high-strength locking system.

Designed to cope with operations characterized by higher peak loads and lower rotation speeds, each UC 300 series unit also features a grub screw locking system set at an angle of 62 degrees, which gives even better holding power.

‘Whatever their need, engineers can now find proven, high-quality and reliable ball bearing units from a single, quickly accessible and trusted source,’ said SKF product manager Jerome Pommereul.

‘Thanks to their greater contamination and vibration resistance, they will last longer, maximize the performance of rotating equipment and minimize productivity losses due to bearing failure.

‘Customers will also see cost savings through fewer replacements and repairs, and if you are an OEM, the reliability of our bearings will reduce operational costs relating to warranty cases, engineering and development.’

UC 300 series units are available with bores up to 100mm. Typical applications include conveyors, belt pulley and chain transmissions, and cranes. They will be of particular benefit in areas such as material handling, construction machinery, quarrying and mining.
