Live Center Applications

The Sprint live center is the “Premiere” live center for high-speed, high-production shaft turning. Manufacturers of axles, motor shafts, and transmission shafts to name just a few, rely on the Sprint live center for their demanding production requirements. Specifically designed for high-rpm turning, the Sprint live center ensures accuracy in the work-piece, consistent repeatability, and the highest through put on the market today.

Live Center Availability

Sprint live centers are available from stock in Morse tapers. Three standard point configurations are offered to provide maximum flexibility. Standard point, tracer point and long point live centers are available from stock. Custom variations of the Sprint live center can be designed using our on-line design tool or by discussing your application with one of our product specialists.

The Sprint live center is also available in stock with a tracer point carbide tip or a standard point carbide tip. Carbide tip live centers provide greater durability for tougher work-pieces. An interchangeable point design, the Quick Point Sprint is also available with standard points, tracer points, bull nose points and female points in stock.

Live Center Technical Specifications

The Sprint live center utilizes three matched angular contact bearings. Our large inventory of precision bearings are graded and matched for size to insure the proper bearing fit. Both the front and rear bearing bores are ground in one operation through a process unique to Riten Industries. As a result, bearing bores are both concentric and coaxial with the Morse taper. Proper bearing alignment and fit are key to providing an accurate live center with improved bearing life.

The shell is manufactured from low carbon steel and case hardened, while the spindle is manufactured from 52100 ball bearing steel and through hardened to provide the maximum strength and durability needed in a live center spindle.

In addition to the primary lip seal, the Sprint comes standard with an external no friction seal. This “coolant deflector” helps provide maximum protection against coolant and other contaminants. Contamination is the primary cause of premature bearing failure. Our double seal design is the proven industry leader in high-pressure coolant applications.

Live Center Repair

Standard Sprint live centers will be rebuilt to “Like New” condition for 40% of the cost of a new tool. This is a total reconditioning of the entire live center. The shell is inspected for damage and the taper shank is reground as needed. The bearings, seals and spindle are replaced with new components and the live center is returned to its original accuracy. Every repair receives the identical factory warranty as that of a new live center.

In the unlikely event that your live center is beyond repair, Riten offers a preferred customer trade-in allowance of up to 35% on the purchase of an equivalent live center. Every Riten live center, no matter its condition, is eligible for trade-in. Repairs can be returned through your local Riten distributor or send direct to the factory.
