SKF filament wound bushings are available as straight bushings in metric sizes. They have excellent dry sliding characteristics and the low friction sliding surface does not require additional lubricant. However, a lubricant can protect against contaminants and has no negative effect. These bushings are developed to accommodate heavy loads, vibrations and provide maintenance-free operation even under those extreme conditions and in corrosive environments.

However, filament wound bushings have only a limited capacity to accommodate solid particles embedded into the filament wound material. Therefore, SKF recommends protecting the sliding surface against the ingress of contaminants (Design of bushing arrangements) when the bushing is to be used in highly contaminated environments.

SKF filament wound bushings, which are often dimensionally interchangeable with solid bronze or steel bushings, can be machined using normal methods on all surfaces, except for the sliding surface. To facilitate mounting, the bushing may be split lengthwise into two halves by using a diamond coated grinding wheel. Sufficient cooling fluid should be applied as well to avoid excessive temperatures, as they can destroy the bushing.

SKF filament wound bushings are manufactured by a winding technique from a self-lubricating composite. The unique sliding surface layer consists of high-strength polyester and PTFE (polytetrafluoroethylene). The backing consists of wound high-strength tensioned glass fibres. Both layers are manufactured by winding endless strands in a criss-cross pattern and are embedded in an epoxy resin matrix so that they are firmly attached to each other.
