Spacers

SPIROL® Spacers are formed into closed seam tubes from cold rolled strip. The component cost savings are achieved through:

  • Use of SPIROL’s proprietary, highly flexible and efficient production technology.
  • SPIROL’s roll formed Spacer design has tolerances that meet application requirements. This prevents unnecessarily close tolerances associated with manufacturing technologies required to produce more expensive alternative products such as cut tubing, machined bushings, etc.

A typical application for a tubular Spacer is to separate two components in an assembly joined by a bolt, rivet or rod passed through the inside diameter of the Spacer. The inside diameter of the Spacer is designed for a clearance fit.

SPIROL’s standard range of SPIROL Spacers includes both metric and inch specifications in a variety of diameters and lengths. Most standard diameters are available in two wall thickness options, standard wall and heavy wall, to accommodate specific application strength and bearing requirements.

  • SP100 standard wall Spacers are typically used in static applications without excessive external forces acting on the joint.
  • SP150 heavy wall Spacers have greater compression strength and additional bearing surface. The additional bearing surface is often used to prevent witness marks or indenting when the Spacer is clamped between soft materials.

This provides an extensive range of sizes, particularly if the inch sizes are converted to metric or vice versa. The benefits of using standard Spacers are as follows:

  • Reduced cost and no tooling charges — particularly in low- or medium-volume applications.
  • SPIROL’s stock allows for just-in-time delivery and reduced inventories.
  • No excess components at the end of a production run.
  • SPIROL’s expansive standard size range meets most application requirements and eliminates the need for custom-designed parts.
