Bearing reduces horsepower loss

The ADVANTAGETM pivoted shoe journal bearing features high speeds and loads while reducing horsepower loss and maximum bearing operating temperatures. The bearing features a flow-directing design that improves efficiency by up to 35%, and maximum shoe temperatures have been reduced by 30F. Lower oil-flow requirements coupled with reduced churning, stirring, and flow-through losses result in horsepower loss reductions of up to 35%.

Gearhead is for servomotors

The StealthTM planetary gearhead is for servomotors and incorporates the HeliCrownTM helical gear, which combines the power of helical gears with the smooth quiet engagement of tooth crowning. The gearheads feature high torque, low backlash, and less than 68 dB noise specification. The gearheads are available in four frame sizes with reduction ratios of 5:1, 10:1, 20:1, 30:1, 50:1, and 100:1. The ServoMountTM design helps mount Stealth to the motor and features a balanced pinion supported by a floating bearing, which provides true alignment of the input pinion and the helical planetary gears. This allows input speeds up to 100,000 rpm.

Conveyor rollers feature spring-loaded tapered shaft ends

TAPERHEX(R) GOLD precision bearing conveyer rollers feature spring-loaded tapered shaft ends that "lock" into the conveyor frame-mounting holes. The locked shafts eliminate roller "rattling," the cause of both roller shaft and side frame wear. The rollers "pop" into the conveyor side frames in the same manner as conventional spring-loaded rollers. However, the self-adjusting tapers wedge tightly and lock into place regardless of the condition of the mounting holes. Applications include use in food processing, beverage and bottling, warehouse and distribution centers, and on assembly lines.

Driver can replace mechanical gearing

The IM481H microstepping driver uses hybrid technology to reduce size and maintains the power and compatibility to handle demanding applications. The driver can replace mechanical gearing for increased smoothness and optimal performance. In addition, surface-mount and application-specific integrated circuit (ASIC) technology allows semiconductors to be more densely manufactured, resulting in downsizing of products. The driver also features short circuit and thermal protection and adjustable automatic current reduction at full step and fault outputs.

Engine mounts isolates vibration

Marine Mount isolators are for internal-combustion and V-drive marine engines. Features include the ability to isolate vibration while transmitting full propeller thrust, efficiently isolating engine noise and vibration from the hull of the vessel. This feature improves engine reliability, reduces mechanical noise transmission, and provides occupant comfort, particularly with in-line cylinder diesel engines while the engine is at start-up or low rpm.

Bearing is for harsh environments

The NylinerTM bushing bearing uses two self-lubricating engineering polymer inserts for fast break-in and reduced wear. The high-performance resin liners snap in for easy replacement. The bearing tolerates abrasive contaminants, shock, and vibration, and provides high-temperature and high-speed operation in both linear and rotary modes. Applications include those with short strokes, high acceleration/deceleration, and high impact. The inserts' internal lubricant eliminates the need for further lubrication maintenance, and closed and pillow-block-mounted Nyliner bearings are offered in 0.5-, 0.75-, 1-, 1.5-, and 2-inch sizes.

Coupling allows smooth transfer of torque

The constant-velocity coupling combines a balanced clamping mechanism with a new configuration to reduce static and dynamic imbalances. The single-slotted clamp provides clamping pressure around the shaft and a more uniform pressure on the outer circumference of the axial-slotted hub. Because the hub has a plurality of axial slots along its entire length, the inside diameter of the hub can be deformed to apply a more evenly distributed pressure against the shaft. The coupling offers a substantially constant angular velocity from the first shaft to the second. Torque is transmitted from the first to second shaft in a smooth and consistent manner.

Motors provide long life in harsh environments

"Wash-Thru" motors feature completely encapsulated windings to protect them from moisture and contaminants. Rather than attempt to seal out the elements, these motors isolate the motor component most vulnerable to moisture damage. The motors are available in NEMA frame sizes 56 through 256T and feature a Class F insulation system, a low temperature rise, and sealed bearings for long life. An additional silicone coating over the encapsulation provides additional protection. The entire motor inside and out is primed by an exclusive e-coat system to provide corrosion protection. Motors have an FDA-approved white finish coat and a 304 stainless-steel shaft.

Honorable Mention

Belt drive system reduces noise

The Goodyear Eagle Pd synchronous belt-drive system is a combination of synchronous belts and sprockets that use a helical offset tooth design that reduces noise. Continuous rolling tooth engagement and flangeless sprocket provide self-tracking and design flexibility. The belt is comprised of specialized materials such as HiBrexTM rubber, Flexten(R) tensile members, and a PlioguardTM fabric facing, which means the belt's width can be reduced without compromising strength.
