Formerly owned by Bethlehem Steel Corporation, the Point Steel Mill was opened in 1889 and was a landmark in Baltimore covering more than 3,400 acres and stretching for miles along the southeast edge of the Baltimore harbor. It employed more than 31,000 workers at one time. Over the years, the facility supplied steel for the Golden Gate Bridge, the Chesapeake Bay Bridge and hundreds of ships for World War II.  After more than 100 years of operations by various owners including Mittal Steel,  Severstal, and finally RG Steel, the mill is currently closed and in liquidation.

“We’re extremely pleased that we were successful in acquiring this bearing inventory,” said Clarence Hopkins, President of Royal Bearing Inc. “This massive inventory has been fully integrated into our existing bearing stock and is now available to our worldwide customer base.”

Cam followers, also known as track rollers, are used to transfer linear or rotational motion. Often a cam follower will move along a flat surface or cylindrical object. A cam follower can withstand high radial loads caused by shock or heavy rolling as well as minor incident thrust loads. Cam followers come in two primary styles: stud and yoke. Stud cam followers have a threaded rod, which can be mounted into a wall or plate with corresponding threads. A standard stud cam follower is mounted solely at one end, and is consequently limited to moderate forces. A heavy stud cam follower may be used if larger loads are required. Stud cam followers are available with a variety of characteristics including hex holes, eccentric studs, coated seals, and single or double rows of rollers. Unlike a stud cam follower, the yoke style does not use a stud for support. Instead, a yoke cam follower mounts on a shaft. A shaft supports the cam follower on both sides, which enables larger load capacity than a standard stud. Cam followers are useful in many industries including automotive, textile, and machine tools.

Tapered roller bearings have two main components: the cup and cone. The cup is comprised of an outer race, while the cone contains a cage, tapered rollers, and an inner race. Both the inner and outer raceway are tapered. Tapered roller bearings support axial and radial loads. The axial and radial load capacity is dependent on the cup angle. A steep cup angle enables the bearing to support large axial load, while a shallow cup angle enables large radial loading. Metric and inch tapered roller bearings have some distinct differences. In general, metric tapered roller bearings maintain a consistent relative cross-section within a series. This is not the case with inch tapered roller bearings. Within a series, inch tapered roller bearings are allowed to mix and match cones and cups. This means that any cone can go with any cup of the same series. Tapered roller bearings are good for applications requiring shock loads, minor misalignment, and high speeds.

Take-up bearings are mounted units that make adjustments to the shaft extension, belt tension, or tracks in a conveyor system. Their structure includes a guide frame, positioning screw, and either plain or roller elements. Agriculture and food processing industries that utilize conveyor systems often require take-up bearings.

Sprockets are profiled wheels with teeth. Unlike gears, sprocket never interconnect, but rather interlock with chain to transfer rotational motion. They are commonly used in conveyor systems. Quick-detach sprockets are used in lumber, paper, and agriculture while taperlock sprockets are used in packaging equipment.

Slewing ring bearings, also called plain bearing turntables, are mounted on surfaces rather than shafts. They enable rotational motion parallel to the support surface. Installation is facilitated by mounting holes located along the inner and outer races. Slewing ring bearings are large in size and support high radial, axial, and moment loads at low speeds. The rolling elements are typically balls or rollers. Slewing ring bearings are utilized in cranes, turbines, and engines.

Sheaves are grooved wheels used to transmit rotational power and torque. They are used in conjunction with a belt which utilizes friction to turn the sheave. Two common types of sheaves include quick-detaching (QD) and variable pitch. Quick-detaching sheaves facilitate convenient mounting and dismounting. They are ideal for situations where sheaves must be changed frequently. Variable pitch sheaves enable speed adjustment. Other kinds of sheaves include taperlock and plain bore. Sheaves are common in conveyors and fans.

Seals block harmful contamination from reaching the inner races and rollers of a bearing as well as prevent the breakdown of lubricant. This protection allows the bearing to perform optimally and elongates service life. Seals are generally located between the rotating shaft and the housing. There are many types of seals including radial, lip, V-ring, and felt.

Roller bearings utilize either cylindrical, needle, tapered or spherical rollers. Rollers carry load on a line contact and as a result can support large radial loads. Cylindrical roller bearings consist of an inner race, an outer race, and cylindrical rolling elements. A cage allows the bearing to operate at high speeds. Long, thin rolling elements, called needles are well suited for bearings with a small diameter, or where high speeds are desired. Tapered bearings are ideal for combined loads. A tapered roller bearing is comprised of one or two cones and a cup. The cone contains an inner race, cage and tapered rollers which roll on the tapered surface of the cup. Spherical bearings are comprised of a concave outer raceway, convex rollers, and either a tapered or cylindrical bore. Spherical rollers enable high radial loads due to the large contact area between the rollers and raceways. In addition, the concave shape of the raceway allows the bearing to self align. Thrust roller bearings are intended for large magnitude axial loads with very little radial loading. They can contain either cylindrical, spherical, tapered or needle rollers. Applications for roller bearings include machine tool spindles, steel mills, and vibrating equipment.

Rod end bearings are used when components must be joined together, such as a shaft or piston head. Two common variations of rod end bearings include solid and ball joint. Solid rod end bearings are one-piece, consisting of a through bore, a solid housing and shank. Ball joint rod ends are perhaps the most common and are available in either two or three pieces. Two-piece rod end bearings include a spherical bushing encased within a single-unit housing and shank. Three-piece rod end bearings are comprised of a single unit housing and shank, spherical bushing, as well as an inner race. The shank may have either male, female, or no threading. A shank with external threading is called male, while internal threading is called female. Materials of the housing, spherical bushing, and inner race vary depending upon the load, friction and rotational requirements. Materials include, steel, stainless steel, nylon and aluminum. Rod end bearings are commonly used in vehicles but are also utilized in machining centers, lift trucks, cranes, and fitness equipment.
