Riten extra heavy duty live centers are designed specifically for those applications requiring load carrying capabilities that exceed that of heavy duty live centers. Applications involving part weights ranging from 3,000 to 22,500 pounds require extra heavy live centers. Part weights in excess of this require Super Duty Live Centers. Extreme loads and heavy stock removal rates are typical when turning rolls, shafts and forgings. Extreme loads and close size tolerances are encountered when grinding these same components. Roll manufacturers, manufacturers of power generation components and large shaft and cylinder manufacturers all rely on extra heavy duty live centers for their work holding device requirements.
Extra heavy duty live centers are available from stock in Morse tapers. Standard point configurations are available from stock. Tracer point and custom configurations can be designed using our on-line design tool or by discussing your application with one of our product specialists.
The extra heavy duty live center utilizes three, large bore, 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 capable of holding extreme weights.
The shell is manufactured from low carbon steel and case hardened, while the spindle is manufactured from tool steel and through hardened to provide the maximum strength and durability needed in a live center spindle.
Standard extra heavy duty 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 you local Riten distributor or send direct to the factory.
