Spyraflo Introduces Self-Aligning Aluminum Pillow Blocks and Housing Flanges
Ideal for Replacing Traditional, More Expensive Ball Bearings
PEACHTREE, GA, April 19, 2005 - With demand increasing for more cost-effective bearing solutions in a wide variety of applications, Spyraflo has introduced a new line of self-aligning pillow block and housing flange bearings mounted in appealing, high-performance aluminum housings. Spyraflo is the only manufacturer to offer a choice of Needle Roller, Teflon Bronze and SAE 840 Bronze pillow blocks and housing flanges. These self-aligning bearings are lightweight and robust, providing a simple, cost-effective solution to often-expensive mounted-bearing problems.
The new aluminum-housed bearings give OEMs and end users a wide variety of design and replacement options. They are the perfect alternative for more expensive, conventional ball bearings that presently may be considered "overkill" in many applications. The pillow blocks and housing flanges offer a number of important benefits, including:
o +/- 5° static self-alignment
o A wide range of loads and speeds
o Multiple bearing mediums
o Superior product appearance
o Non-corrosive housings
o Significant weight saving
The ±5° self-aligning feature solves many problems associated with bearing misalignment A spherical insert is held in place by the outer retainer allowing the insert to pivot 5° in any radial inclination, thereby ensuring smooth shaft alignment and rotation. Drive shafts, adjustment rods, chassis' and machines can all profit from the benefits of this self-aligning capability.
Another benefit of the Spyraflo SAE 840 Bronze product is the 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 results in a 30% loss of oil lubricant, significant carburization of the remaining oil, and increased viscosity, all leading to a reduction in performance. The Spyraflo housings are precision manufactured in sintered aluminum - as opposed to the traditional cast aluminum process - thereby ensuring a high degree of consistent dimensional accuracy, clean lines and an appearance unmatched in the industry.
Spyraflo aluminum pillow blocks and housing flanges come in a variety of inch and metric sizes, and Spyraflo provides a simple part number interchange chart for the SAE 840 Bronze that enables you to make an easy transition from the competitive brand to the replacement Spyraflo bearings.
Sizes include:
Needle Roller - 0.250" (6mm) to 0.750" (18mm)
Teflon Bronze - 0.250" (6mm) to 1.000" (25mm)
SAE 840 Bronze - 0.250" (6mm) to 1.250" (30mm)
