Tool aligns V-belt pulleys

SheaveMaster mounts magnetically to the face of a pulley. A permanently calibrated laser beam fans out, striking three magnetic targets on the opposite pulley and measures angular, offset, and twist misalignment of the drive. The device can also be used on chain drives. It only requires one person to operate and can be used indoors and outside. Ludeca, Inc.; www.ludeca.com

Belt increases capacity and cuts maintenance

Poly Chain GT 2 belt is ideally suited for synchronous drives less than 500 rpm and horsepowers up to 1200. The belt transmits up to 30% more power than its predecessor does. This version permits the design of more compact, lighter weight drives. When combined with Taper-Lock sprockets/bushings, lifetime parts replacement and maintenance costs are reduced.

Bearings’long life reduces maintenance

Explorer spherical roller bearings last up to three times longer than comparable products under carefully controlled endurance tests. This highly durable bearing is dimensionally interchangeable with existing ISO-design spherical versions. Replacing these bearings reduces maintenance costs and increases load capacities of equipment. SKF USA, Inc.; www.skf.com
