Heavy duty compression springs are ideally suited for applications where high loads are needed and limited space is available. SPEC heavy duty springs are designed to work in a hole or over a shaft.
| ||Chrome Silicon per Associated Spring SV 9254 or Chrome Vanadium per SAE 6150 - rectangular wire with rounded corners |
| ||These materials are not recommended for applications where the temperature exceeds 425 deg F (220 deg C). |
Direction of Helix - Right Hand
| ||Squared and ground |
| ||Free length is for reference only |
| ||O.D. and I.D. are designed to fit in hole or over rod as specified in table. Outside diameters are dimensioned to allow a minimum of .020" clearance in the specified hole diameter when the spring is in the free state |
| ||To determine approximate solid height; see notation number in hole size column. Multiply the free length by the appropriate values that correspond to the notation number 1 x .53 - 2 x .65 - 3 x .73 - 4 x .77 |
Standard finish is that of the normal wire. Due to residual stresses induced during the manufacturing process electroplating is not recommended. Other finishes available on request.
