Original Solution	Spyraflo Solution

Overview: The customer was using a precision-machined bushing that was pressed into a precision hole in the machine frame. The bushing then retained the 12mm needle roller bearing. Problems: The precision bush was expensive and the tolerance build up resulted in the bushing having to be glued in or an undersized bushing was used. The assembly was time consuming, expensive and ineffective.	Solution: A punched hole replaced the machined hole in the frame. A standard Spyraflo self-clinch, non-align retainer with a 12mm needle roller bearing mounted in it replaced the precision bushing and the need to install the bearing separately. Clinching the bearing assembly resulted in a secure, shake-proof mounting. The small clinch zone ensured no bearing closure. The customer had a better solution in terms of bearing mounting and size, and also had cost savings on material and labour.

Overview: The customer had a low cost U-section sheet steel chassis that required a single shaft to run between the two vertical faces. The shaft was stepped, making one bearing 6mm and the mating bearing 4.5mm. The chassis was stamped out; including the mating holes and then bent into the U-shape. Problems: This process resulted in the mounting holes always being offset requiring extra machining operations and additional assembly tasks.	Solution: Spyraflo self-clinch, self-align Delrin 6mm and 4.5mm bearings were clinched into the punched holes. The self-clinch option meant the installation was quick, easy and secure. The self-align capability accommodated the offset in the mounting holes and ensured a smooth running shaft every time. This resulted in a better bearing solution, cost savings during assembly and in machining, and a 100% product performance.

Overview: The customer had a requirement for a 900mm long by 16mm diameter shaft to carry a heavy load while moving very smoothly. The lengthy shaft had to be supported at multiple locations along its length. Problems: Cost was an issue and it was necessary to use formed sheet steel mountings along the length of the shaft. This necessitated the requirement for a self-aligning needle roller bearing assembly.	Solution: Spyraflo flange-mounted, self-align 16mm needle roller bearings were bolted to each individual support. Flange-mount was used for service reasons and to give vertical adjustment. The self-align ability compensated for the lack of the perpendicular support on the shaft. This resulted in enhanced product performance, quick assembly and cost savings.

Overview: The customer wanted to reduce machine costs by using two plastic injection moulded side plates in place of steel. The side plates housed bearings for three shafts, which transported paper products. Problems: Alignment issues became apparent between the side plates causing the shaft to bind and not run smoothly.	Solution: The Spyraflo press-fit, self-align 6mm bronze bearings were pressed into the moulded holes. The 5° static alignment capability of the bearing resulted in a smooth running shaft and easy assembly every time. This also resulted in cost savings on overall assembly and enhanced performance.
