Spacers and Tubular Products

Customized to Meet Your Requirements

Special Lengths
Any length from 3/32" to 6" or 2.5 mm to 150 mm, subject to some limitations relative to diameter and wall thickness.

Special Inside Diameters
Any diameter between 5/64" to 1" or 2 mm to 25.5 mm. Reduced tolerances are also available.

Specified Outside Diameters
The outside diameter can be specified with minimum and maximum tolerances but it is then suggested to specify the inside diameter only with a reference dimension or only with a minimum dimension rather than a minimum/ maximum tolerance to reduce cost.

Both Diameters Specified
In situations which require both the inside and outside diameters to be specified with tolerance dimensions, a decision needs to be made as to which dimension should have the tighter tolerance so that the strip thickness tolerance can be properly allocated.

Gap
Spacers are usually butted with minimal or no gap. The gap can be specified from "no gap" to a tolerance or maximum specified gap.

Special Wall Thickness
The ideal thickness is 15% of the mean inside diameter up to a maximum of .140" and 3.5 mm. A range of 10% to 25% of the mean inside diameter is possible depending on material type and tolerancing requirements.

Concentricity
When necessary, with OD/ID reduced tolerance spacers, concentricity can also be a specification.

Special Length Tolerances
Standard spacers have a generous length tolerance to keep the cost down. Reduced tolerances can be provided to .004" and 0.05 mm and in some instances even these tolerances can be further reduced. Tight tolerances increase costs. Tolerances should be tailored to the needs of the application to eliminate unnecessary expense.

Special Materials
Virtually any material available in cold rolled strip form can be used. Some of the more frequently specified materials are brass and higher carbon steels for hardening purposes.

Increased Columnar Strength
Can be achieved through increased wall thickness, higher strength material, or by using materials that can be heat treated.

Perpendicularity
The ends of standard spacers are square to the axis of the spacer but, to minimize cost, are not a controlled dimension. When required, perpendicularity can be specified.

Special Finishes
Finishes are only limited by market availability. Finishes are specified for corrosion protection, color coding, and appearance. Stainless steel or brass should be considered in lace of finishes, since these can result in a better product at a lower cost.

Headed spacers/rivets
These are readily available in both spacer and rivet dimensions and are used in place of expensive long semi-tubular rivets.

Shoulder rivets
These have found a use in unique applications as a standoff, riveted in place.
