BANTAM™ Mini Compression Springs

BANTAM Mini Compression Springs banner

The world is shrinking every day and so are the size requirements for springs. Lee Spring has once again listened and responded with Stock Spring solutions designed to solve your growing requirements for smaller sizes.

BANTAM™ Mini Compression Springs are Lee Spring’s unique line of miniature springs. These Stock products are offered in wire sizes .0040”, .0045”, .0050” and .0055”. The imperial sizes (prefix CB) include selections to work inside hole diameters 1/32", 3/64" and 1/16" and in a range of free lengths from .050" up to .625". The metric sizes (prefix CBM) include selections to work inside of hole diameters 1mm, 1.5mm and 1.8mm in a range of free lengths starting at 1mm up to 12mm. The ends are closed and squared, not ground. In order to meet and maximize the performance needs of a potentially diverse range of applications, Lee Spring selected Elgiloy® as the alloy for Stock BANTAM Mini Springs.

Elgiloy® is a Cobalt-Nickel alloy known for its high strength, e.g. 10% stronger than Type 316 Stainless Steel. It exhibits superior resistance in most corrosive environments including acetic acid, ammonium chloride, citric acid, sodium chloride and sodium sulfite. This material performs in temperatures up to 850° F and as low as -300° F. Elgiloy® is non-magnetic.
