Ameriloc Internal Locking Devices

MODEL 3003

Locking Assembly, consisting of internally slotted bush and externally slotted ring. These are clamped together by locking screws, thus mating the shaft with the bore of the hub. High degree of concentricity. Removal by means of jacking screws.

Model No.	Range	Torque Range
3003	.78" Shaft x 1.85" Bore - 15.74" Shaft x 19.48" Bore	221 ft. lbs. - 291,706 ft. lbs.

MODEL 3006

When compared with the model 3003, the difference is the larger flange of the internal bush, preventing axial movements of shaft and hub.

Model No.	Range	Torque Range
3006	.78" Shaft x 1.85" Bore - 15.74" Shaft x 19.48" Bore	207 ft. lbs. - 261,835 ft. lbs..

Ameriloc Internal Locking Devices - Model 3012

MODEL 3012, MODEL 3015

Higher torque transmission values than for models 3003 and 3006. Additionally, collar on the inner face of the external bush results in shorter fitting and removal time.

MODEL RB

Especially for conveyor pulleys (with low surface pressure).

Model No.	Range	Torque Range
3012	.98" Shaft x 1.96" Bore - 20.47" Shaft x 24.21" Bore	479 ft. lbs. - 1,025,211 ft. lbs.
3015	2.75" Shaft x 4.33" Bore - 23.62" Shaft x 27.36" Bore	5,274 ft. lbs. - 914,577 ft. lbs.
3015.1	2.75" Shaft x 4.33" Bore - 23.62" Shaft x 27.36" Bore	221 ft. lbs. - 291,706 ft. lbs.
RB	3.94" Shaft x 5.71" Bore - 24.41" Shaft x 28.74" Bore	5,863 ft. lbs. - 576,183 ft. lbs.

MODEL 3020

Two tapered rings are locked together by screws forcing one slotted internal and one slotted external ring against the respective shaft and hub surfaces. Machining tolerances are loosened to allow for greater range of fit. Removal is simple as the cone angles prevent binding. For the transmission of higher torque values several locking assemblies can be used in series.

Model No.	Range	Torque Range
3020	.78" Shaft x 1.85" Bore - 19.68" Shaft x 23.81" Bore	236 ft. lbs. - 494,167 ft. lbs.
3020A	.78" Shaft x 1.85" Bore - 19.68" Shaft x 23.81" Bore	199 ft. lbs. - 560,000 ft. lbs.
3020S1	.78" Shaft x 1.85" Bore - 3.74" Shaft x 5.31" Bore	80 ft. lbs. - 2,331 ft. lbs.
3020S2	.78" Shaft x 1.85" Bore - 3.74" Shaft x 5.31" Bore	199 ft. lbs. - 5,827 ft. lbs.
