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.

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.
