Shaft Features
Nominal Diameters
We offers one of the widest ranges of standard inch and metric diameters in Canada ranging from 1/8" to 4" and from 2mm to 150mm.
Available Tolerances
Stocked tolerances in inch include Class L, S, R(N) and D(oversize) and in metric h6(M). Custom diameters and special precision tolerances are also available.
Shaft Lengths
Single length shafts are available up to 240” for most diameters including 3/4” and above, and 188" for diameters below 3/4". Extra-long lengths are available by special order.
Length Tolerances
Our standard length tolerance is ±1/32" for diameters below 2" and ±1/16" for diameters including 2" and above. Tighter tolerances are available by special order.
Material Options
Standard material is induction case-hardened carbon steel with a Rockwell hardness of 60-65C. Other materials available include stainless steel (Rockwell 50-55C), chrome-plated steel, tubular carbon and tubular stainless steel. Special materials can be supplied as required.
Quantity and Delivery
For regular stock, shafts can be cut and shipped from one of our warehouse on the same day that the order is received. All shafts are coated with a corrosion inhibitor and packaged in cardboard tubes or wooden crates for protection and to ensure that straightness tolerances are maintained during transport. Alternative packaging methods are available. Customized delivery times and schedules can be arranged if requested.
Pre-Drilled Shafting
A wide range of pre-drilled linear shafting and support rails for any number of configurations and applications are available. Please click here for more information.
Custom Machining:
A full range of machining services are available including special chamfers, straightness tolerances and surface finishes as well as custom drilling, tapping, flats and keyways. in addition, our European machining facility can custom grind linear shafting to any diameter, tolerance and to any other specifications that you may require.
