|ER-style bearing covers a range of applications|
|Use Baldor Electric Co.’s Dodge ER-Style ball bearings for a range of applications such as material and unit handling, conveying equipment, and agricultural, paper, packaging and printing machinery. They’re available in two shaft attachment methods. The setscrew has a 65-degree angle for maximum shaft grip. The D-Lok product offers a clamp collar grip for maximum concentricity to minimize vibration. Snap-ring retention securely fits the cylindrical outer diameter into equipment and the Dodge ProGuard seal and flinger package prevent contamination. The setscrew ranges from ¾-in. bore size (204 series) to 3-7/16 in. (218 series). The D-Lok style comes in a ¾-in. bore size (204 series) to 2-7/16 in. (212 series). Baldor, a member of the ABB group, is based in Fort Smith, Ark.
|Speed reducers handle heavy duties|
|A new line of Boston Gear 752 size worm gear speed reducers meet the demands of heavy-duty conveyor systems or any large shaft mount applications. These new models have hollow output shafts in 5.25-in. centre distance and output torque ranging up to 12,250 lb.-ft., more than double when compared to 738 centre distance. Six new bore sizes range from 2- to 3-7/16 in. Double reduction ratios are also available. Housings for all 700 Series reducers are rugged cast iron with high-strength bronze worm gears mounted between heavy-duty tapered roller bearings. The 752 models are backwards compatible with all 700 industry-standard mounting dimensions.
Boston Gear, based in Charlotte, NC, is a global supplier of power transmission products.
|Bearings handle higher loads|
|Cooper Roller Bearings has increased the load capacities of many of its split roller bearings to levels it claims are higher than bearings of similar size, with L10 life that’s 23% to 135% longer (depending on size). The 01E (medium-duty) and 02E (heavy-duty) bearings are interchangeable with the Cooper 01 and 02 Series, yet provide up to 29% more radial capacity and 16% to 90% more axial load capacity. They’re completely split to the shaft to eliminate disassembling during service or replacement, which significantly reduces downtime. Sealing and energy efficiency is the same as the 01 and 02 Series, but they also share the same exterior dimensions for more capacity in the same space. Rugged brass cages make them suitable for underground applications and other challenging environments. Bore sizes range from 6.5 to 12 in. (160 to 300 mm). Cooper Roller Bearings is a manufacturer of split-to-the-shaft roller bearings based in Norfolk, Va.
|Harness drive.web control|
|Sprint Electric’s digital DC drives harness a new technology (drive.web) that provides control over the ethernet without a PLC or supervisory computer. The drives, up to 2,250 A, control DC motors used in heavy industry applications such as metal working, steel mills, mining, or the cement, rubber and plastics industries. All models ranging from 650 to 2,250 A (980 kw/1,320 hp) feature two AC busbar position options: top or bottom entry. Compared to the standard voltage this provides an increase in shaft power, up to 1,500 kw/2,000 hp for the 2,250 A model. That’s 50% more power delivered without an increased cable size. The PLX has an extensive range of software functions and fieldbus communications options such as Profibus, DeviceNet, CC-Link, EtherNet/IP, Modbus and CANopen. Sprint Electric Ltd., based in England, is a global supplier of motor control products. Its products are distributed by MDA Controls Inc., in Oakville, Ont.
