ROUND WIRE COIL SPRINGS –WY (75% DEFLECTION) –

ALTERATION OF PAINT–PEELING OF COIL SPRINGS

■ Spring constant

We stock all our coil spring products after painting for the purpose of identification and rustproofing. However, in an attempt to satisfy customers who are troubled by coating coming off, we have started providing alteration of paint–peeling of coil springs.

e D12/14 of WY type are not available.

■ Overview Alteration of paint–peeling applies shot peeling to the painted coil springs to peel off its painting, then grease is applied for rust prevention. After the total processing, the paint for identification is completely peeled off, and the bare spring material is exposed.

■ Notes on handling • Although antirust agent is applied to the paint–peeled springs, oil tempered wire for spring used on the coil springs is extremely vulnerable to rust. Please be careful in handling them.

• Since rusted springs could cause early breakage, we recommend customers to reduce the deflection rate of paint–peeled springs compared to the regular painted products and replace them periodically depending on the usage environment. Early use after purchasing is also recommended.
