Are your bearings causing you problems?

  • Insecure mounting
  • Need a minimum footprint
  • Assembly difficulties
  • Excessive Wear
  • Misalignment
  • You want minimal maintenance

We have the answer!

A leading manufacturer of home and commercial, either manual or computer-controlled quilting machines wanted to expand their various configurations to deal with the burgeoning home business market and industrious homemaker. They determined a larger capacity machine was required to augment the most successful due to customer feedback reinforcing the need for a 6.5cm throat. This resulted in them designing and developing a new machine that presented several design challenges.

SpyrafloThe first challenge was to deal with an intermittent significant radial load applied as the needle pierces the quilt material up to 2,200 times a minute. The motor drive being located at the rear of the machine while transferring motion to the oscillating needle and foot mechanism at the front of the machine more than 6.5cm away.

They required a minimum bearing life of 5,000,000 stitches, it had to be maintenance free for the life of the machine and yet still retain the sleek lines of their current successful machine.

They turned to Spyraflo who recommended the extensive self-aligning custom bearing design experience to provide a self-aligning SAE-840 Bronze bearing solution to meet its extreme performance requirements. Extending the outer parallel diameter and adding a second locating flange modified the self-aligning, press-fit bearing design.

The resulting design allowed 10mm and 12mm diameter bearings to be dropped into the body of the quilting machine positioned in a semi-circular nest. The bearings were located axially by the two flanges and clamped in place by a mating semi-circular strap. The self-aligning capability facilitated easy machine assembly and resulted in smooth shaft start up with minimum friction.

Sales of the new machine have exceeded the company’s expectations and given engineers ideas for further developments and upgrades across the range of their existing machines. Micromech is the UK and Eire distributor for these clever bearings and if you wish to find out more or perhaps request a sample then contact Alan Spinks on 01376 333333 or alan@micromech.co.uk
