Torsion Spring: OD 0.859 in, 360 Degree, Right Hand Wind, Stainless Steel

Torsion Springs

Selection to Match Your Needs.

Lee Spring LTR051J 08 S is a precision torsion spring from the Torsion Springs, engineered for applications requiring reliable quality rotational force. This spring features a 0.859-inch outside diameter (21.82 mm) designed to work over a rod/mandrel of 0.625 inch (15.88 mm) with a 0.051 -inch wire diameter (1.3 mm). Made from this spring delivers a maximum torque of 2.892 lb-in (326.752 N-mm) through its 7.5 total coils with a deflection to max torque of 360 degrees for predictable angular performance. The spring features legs with a length of 2 inch (50.8 mm) positioned at 360 degrees in the free position, operating at a radius of 1 inch (25.4 mm) with a body length of 0.43 inch (11.02 mm). This torsion spring has Passivate per ASTM A967 and a Right Hand direction of wind and provides consistent rotational force for optimal performance in angular displacement applications.

About the Torsion Spring Series

Lee Spring's Torsion Springs have been carefully designed to represent the most commonly used specifications in both inch and metric sizes. Torsion Spring selection are available in seven categories based on the free position of legs (90°, 120°, 180°, 210°, 270°, 300°, 360°) and both left-hand and right-hand wound springs are available.

Direction of Wind:

Good design dictates that torsion springs should be used in the direction that winds the coil. When ordering, select either LTL (standard left-hand wound) or LTR (standard right-hand wound) for required application.

Mandrel Size:

Generally, torsion springs are used over a mandrel (shaft or arbor). The column "Suggested Mandrel Size", allows approximately a 10% clearance for the various deflections shown in examples below. If you require greater deflection, a reduction in mandrel size is suggested.

Torsion Springs Torsion Springs have useful applications in various industries, including:

  • Medical devices
  • Firearms
  • Pharmaceutical delivery devices
  • Lighting and electrical control
  • Petro-chemical processes
  • Communication devices
  • Aerospace
  • Testing and measurement equipment
  • Marine applications
  • Automotive
  • Locks and security devices
  • Precision Instruments
  • Hardware

...and many more applications
