The Timken Company is now producing hot-rolled seamless mechanical steel tubing up to a maximum outside diameter (OD) of 13 inches. Timken is the only North American manufacturer with the capability to produce hot-rolled seamless mechanical tubing in this size range. The company increased its hot-rolled carbon and alloy steel tube manufacturing capabilities to meet demand from customers in the industrial, energy and bearing markets. The larger tubes are used to produce parts for applications such as pulleys, gears, bearings and cylinders.

The new OD sizes are 12.5 inches, 12.75 inches and 13 inches with walls from 1.5 inches to 3 inches in ¼-inch increments. Commonly produced grades are 1018, 1026, 1030, 4130, 4140 and 8620. The addition of this size extends Timken’s range of hot-rolled seamless mechanical steel tubing from 2 inches to 13 inches OD and from .25 inches to 3 inches wall.
