Composite bearing housings

SKF ball bearing units with composite housings are part of SKF's extensive range of cost-effective products. These lightweight, ready-to-mount units are particularly suitable for applications with relatively high speeds and moderate loads, and where reliability and minimal maintenance are key factors.

Premium housing

SKF housings are made of glass-fibre-reinforced polyamide material (PA6). These lightweight housings are resistant to a variety of chemicals and diluted acids.

Housing highlights include:

• Excellent corrosion resistance
• Tolerant of high and low temperatures
• Lightweight
• Dimensionally interchangeable with cast iron units
• Excellent UV resistance
• Recyclable
• Available with end covers

Relubrication-free units

The sealed bearing insert is prelubricated with a lithium/calcium-based grease. This long-lasting, water-resistant grease, combined with highly effective integral seals and the high-performance design of properly selected SKF ball bearing units, can provide long, reliable service life without the cost and environmental issues associated with relubrication.

Sealing solutions, bearing designs and materials

Ready-to-mount SKF ball bearing units with composite housings are available as standard with different bearing designs and different sealing solutions.
SKF composite housings can be assembled with all suitable SKF bearing insert designs. This includes all locking methods, all material options (e.g. zinc-coated rings and stainless steel bearings) and all sealing options.
