Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, ground, and polished to meet tight diameter and straightness tolerances.

Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 316 stainless steel shafts have excellent corrosion resistance.

Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.

Linear Motion Shafts

Smooth, hard, and wear resistant, linear motion shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. All are turned, ground, and polished to tight diameter and straightness tolerances.

Steel shafts are generally stronger than aluminum and stainless steel shafts but not as corrosion resistant. 52100 alloy steel shafts are for high-load applications. They have the highest yield strength of any steel shaft; however, they are more difficult to machine than carbon steel shafts.

Stainless steel shafts are more corrosion resistant than steel shafts; however, they’re not as hard as steel shafts and can be more difficult to machine. 17-4 PH stainless steel shafts have excellent corrosion resistance and high yield strength to support heavy loads.

Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.

Hardened shafts are heat treated for increased wear resistance. Case-hardened shafts are hardened only on the surface of the shaft, which increases wear resistance while allowing the center to remain soft for absorbing stresses caused by shifting loads.

Dowel Pins

Use dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. For a tight fit, your hole should be equal to or slightly smaller than the diameter shown. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Steel pins are the strongest dowel pins. Steel pins are precision ground except for 1/32" diameter pins. Stainless steel pins are more corrosion resistant than steel pins. Pins that are passivated offer added protection against corrosion and oxidation. Stainless steel pins are precision ground except for 1/64" diameter pins. 18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic. 316 stainless steel pins have the best corrosion resistance of our stainless steel pins. They may be mildly magnetic.

Metric pins meet either DIN 6325-m6 specifications for steel pins or ISO 2338-m6 specifications for stainless steel pins. DIN 6325-m6 is functionally equivalent to DIN EN ISO 8734, with slight differences in hardness and length tolerances.

DIN 7 is no longer an active specification and is superseded by ISO 2338-m6. They are functionally equivalent with slight differences in length and the pin ends. DIN 7 has rounded ends where ISO 2338-m6 has chamfered ends.

Undersized Dowel Pins

Slip these pins in and out during maintenance or prototyping—they’re undersized to make alignment easier. Unlike standard pins, which fit tightly inside holes, these are designed to give you some wiggle room. Chamfered ends make them easier to insert. The breaking strength listed is double shear, which is the amount of force required to break a pin into three pieces.

Steel pins are very strong. They are best for dry environments.

18-8 stainless steel pins can be used in wet and humid environments without rusting, but they are not as strong as steel.

All metric pins meet ISO 2338-h8, which means they adhere to international standards for dimensions and tolerances.
