Self-Aligning aluminium pillow blocks and flanges cut costs

New from Micromech are self-aligning bearings mounted in high-performance aluminium pillow block and housing flange housings. These new lightweight, corrosion-resistant, robust bearings can be used with a wide range of loads and speeds. They offer a variety of design and replacement options and are an excellent alternative to the more expensive cast iron mounted ball bearings that may be considered 'overkill' in many applications.

The bearings, which are manufactured by Spyraflo, provide a number of important benefits, including non-corrosive housings, superior appearance and 5deg static self-alignment capability - which solves many problems associated with bearing misalignment.

Both the pillow block and housing flange lines come with various bearing options, including SAE 840 bronze, Teflon-Bronze and needle roller bearings. A significant benefit of the SAE 840 bronze version is its ability to maintain superior integrity of the oil lubricant during manufacture, thereby significantly enhancing bearing performance. This is a major advantage over the main competition, whose manufacturing process is said to result in 30 per cent loss of oil and significant carburisation of the remaining oil, leading to a major reduction in performance and life.

These useful bearings are available in sizes from 6mm to 30mm diameters and, because the housings are manufactured in sintered aluminium, they ensure a high degree of consistent dimensional accuracy. With multiple bearing choices, being lightweight, corrosion-resistant, and easy to install, these self-aligning bearings offer a cost-effective alternative.

Micromech is the UK and Eire distributor of these clever bearings.
