The system includes a base, frames on opposite sides of the base, a plurality of rollers each having a bearing, an attachment axle, a drive shaft, a drive belt connecting the draft shaft to one of the bearings, and connecting belts connecting the bearings. The bearings may be disposed between the frames such that the drive belt and connecting belts are protected between the frames or may be disposed within the frames such that the drive belt and connecting belts are protected within the frame when a cover is attached to the frame. ## Claims ### Claim 1 A conveyor system for conveying a package, the conveyor system comprising: a base; frames on opposite sides of the base; a plurality of rollers each having an outer circumference, a first end, and a second end; a bearing disposed in the first end of each roller and having a first channel and a second channel; a cap disposed in the second end of each roller; an attachment axle extending through each of the rollers, caps, and bearings configured to attach the rollers, caps, and bearings to each of the frames; a drive shaft; and a cover disposed on an outside portion of each of the frames; wherein the drive shaft is connected to one of the bearings via a first drive belt; and wherein the covers and frames are configured to prevent access to the first drive belt from lateral sides of the conveyor system. ### Claim 2 (depends on 1) The conveyor system according to claim 1, wherein the cover is pivotable between a first position and a second position, wherein the cover is attached to the frame in the first position and an inside of the frame is exposed when the cover is in the second position. ### Claim 3 (depends on 1) The conveyor system according to claim 1, wherein the drive shaft is disposed within one of the frames. ### Claim 4 (depends on 1) The conveyor system according claim 1, wherein the bearings of each roller in a roller section are chained together by connecting belts. ### Claim 5 (depends on 1) The conveyor system according to claim 1, wherein the drive shaft is connected to a second bearing via a second drive belt. ### Claim 6 (depends on 1) The conveyor system according to any one of claim 1, wherein the conveyor system is configured to be attached to a second conveyor system. ### Claim 7 A bearing for use in a conveyor system, the bearing comprising: a first end; a second end opposite the first end; a first channel for receiving one of a first connecting belt and a first drive belt; a second channel for receiving one of a second connecting belt and second drive belt; and an attachment bore extending inwardly from the second end. ### Claim 8 (depends on 7) The bearing according to claim 7, further comprising a third channel, wherein the third channel is configured to retain the bearing in an upper position of a frame of a conveyor system. ### Claim 9 (depends on 7) The bearing according to claim 7, wherein the first end may be press fit into an end of a roller. ### Claim 10 (depends on 7) The bearing according to claim 7, where the bearing may be disposed within an outer frame of a conveyor system. ### Claim 11 (depends on 7) The bearing according to claim 7, wherein the first and second channels are rounded. ### Claim 12 (depends on 7) The bearing according to claim 7, wherein the attachment bore is hexagonal. ### Claim 13 A conveyor system for conveying packages, the conveyor system comprising: a base; frames on opposite sides of the base having a proximal portion, a top portion, a bottom portion, a top distal portion, and a bottom distal portion; a plurality of rollers each having an outer circumference, a first end, and a second end; a bearing disposed in the first end of each roller and having a first channel and a second channel; a cap disposed in the second end of each roller; an attachment axle extending through each of the rollers, caps, and bearings and configured to attach the rollers, caps, and bearings to each of the frames; a drive shaft; and a cover disposed on an outside portion of each of the frames; wherein the drive shaft is connected to one of the bearings via a first drive belt; and wherein the rollers are disposed between the frames and at least a portion of each of the bearings is disposed within one of the frames such that the drive belt is disposed within the frame. ### Claim 14 (depends on 13) The conveyor system according to claim 13, wherein the drive shaft is disposed within the frame including the drive belt. ### Claim 15 (depends on 13) The conveyor system according to claim 13, wherein the bearings of each roller in a roller section are chained together by connecting belts. ### Claim 16 (depends on 15) The conveyor system according to claim 15, wherein the connecting belts are disposed within the frame including the drive belt. ### Claim 17 (depends on 13) The conveyor system according to claim 13, wherein the drive shaft is connected to a second bearing via a second drive belt. ### Claim 18 (depends on 13) The conveyor system according to claim 13, wherein the attachment axles are secured in the top distal portions of each of the frames. ### Claim 19 (depends on 13) The conveyor system according to claim 13, wherein the rollers and bearings are moveable within the frame from a lower position to an upper position. ### Claim 20 (depends on 13) The conveyor system according to claim 13, wherein the cover is pivotable between a first position and a second position, wherein the cover is attached to the frame in the first position and an inside of the frame is exposed when the cover is in the second position.
