Self-aligning Bearings Keep Taper on Track
In its quest to assist a manufacturer in keeping things taped, Spyraflo helped Marsh Shipping Supplies launch the TD 2100 electric taper. The machine, which Marsh states is the most effective and efficient tape dispenser it has ever produced, is used to accurately, but effortlessly dispense predetermined lengths of gummed paper tape. Key to the innovative design is the high coefficient of friction urethane wide-track feed and pinch rollers.
Alignment of these rollers and other shafts in the mechanism was very critical, as they had to ensure smooth, quiet and efficient operation.
The company wanted an elegant but rugged all metal construction and it became very apparent to the designers that bearings which could be easily mounted in sheet steel and offer self-alignment would be the ideal solution.
They decided after trials of other methods to use self-clinching, self-aligning, Delrin bearings.
To meet their needs the Spyraflo FSD-625 and FSD-375-AF bearings are used throughout the machine.An additional benefit of their selection was the cost saving through low component needs (no bearing blocks or fixings) and easy assembly.Micromech is the UK and Ireland distributor for these clever bearings.
