We have selected a variety of SETCO high performance machine spindle designs to illustrate expertise in precision CNC spindles.

Spindle Designs with High Reliability & Build To Last

SETCO spindle designs offer the machine builder higher performance in low maintenance packages. As a leader in spindle technologies, our expertise provides us the ability to achieve higher performance, increase reliability, and reduce your operating costs. Our designs are easily customized to meet customer and application requirements.

By applying state-of-the-art spindle technologies, we can deliver a spindle that will increase productivity and and reduce your manufacturing costs. For example, we use high performance greases, exclusively formulated for SETCO, to allow higher permissible operating speeds and lower operating temperatures. In most cases, we offer longer spindle life without the use of costly air/oil lubrication systems.

Another example is the use of hybrid bearing materials and bearing technologies to allow for higher load capacities, speed, and increased precision. The use of hybrib bearing technologizes allows for lower operating temperatures at higher speeds.

Our revolutionary seal design, the patented SETCO AirShield™, eliminated the problems caused by contamination and coolant ingress; the most common reason for all spindle failures to maximum spindle performance and reliability to help reduce your spindle maintenance costs.

SETCO AirShield™ Eliminates Bearing Contamination Problems

Historically, the most common spindle failure is caused by bearing failure due to contamination from coolant ingress, condensation, contamination, or chip damage. In most cases, contamination enters the spindle because the spindle seal failed. The SETCO AirShield™ eliminated spindle failure due to bearing contamination and proven itself as the best and most reliable spindle seal in the industry. This statement is proven by extensive testing over 5 years without a single failure attributable to the AirShield™ performance and backed by the longest and best warranty in the industry. The SETCO AirShield™ is the most reliable spindle seal in the industry and carries a 3-year standard limited warranty!

The patented AirShield™ design is the only spindle seal that offers both dynamic and static protection for 100% elimination of coolant ingress and spindle contamination. Unlike other spindle air seal systems, the AirShield™ design does not inhibit spindle bearing lubrication. It is non-contaminating and maintenance free requiring only clean and dry shop air.
