In addition to "bulk items" such as beer cases, cement bags, and grain bags, it can also be used in belt conveyors that transport "loose items" via skirt rubber. It is also compatible with conveyors using corrugated belts and steep incline belts.

• Conveyor
• roller
• Belts and pulleys

This is a roller of the flat carrier idler (JFC type) made into an impact type. The impact rubber with a groove shape reduces the impact of falling materials from the hopper or chute by deforming, thereby alleviating damage to the belt and idler.

This is a Laura two-chamber carrier idler. Its application is similar to that of a standard carrier idler, but it can also be used for conveyors with ribbed belts.

• Conveyor
• roller
• Belts and pulleys

This is a carrier idler connected by joint links for each roller. Its purpose is similar to that of a standard carrier idler, but it has the function of preventing load spillage and belt wandering by deforming in response to the occurrence of uneven loads during transport.

• Conveyor
• roller
• Belts and pulleys

It is an idler that can tilt the stand in the direction of belt movement. It helps to reduce "work time" and "risk rate" during roller replacement.

• Conveyor
• roller
• Belts and pulleys

When the belt comes into contact with the guide roller positioned in front of the pivot axis connecting the upper and lower double-structured frame, the frame (F2) pivots within a certain angle range. The resultant force generated at this time, due to the function that returns the belt to the center of the conveyor, allows for adjustments of wandering and misalignment with minimal force applied, resulting in less damage to the belt.

• Conveyor
• roller
• Belts and pulleys

This is an automatic centering carrier idler with a tapered design based on the JAC type side roller. Due to the larger diameter on the center side of the belt and the smaller diameter on the end side, the difference in surface speed of the roller during belt contact allows for lateral adjustment. The frame pivots towards the side where the belt is offset, enhancing functionality. It can be used without the need for directional indication and is compatible with both forward and reverse operation conveyors.

• Conveyor
• roller
• Belts and pulleys

Similar to the JAC-T type, this is a tapered automatic centering carrier idler with side rollers. The principle of the snake adjustment function is the same, but as a structural difference, a pivot axis is arranged at the bottom of each roller support on the left and right, eliminating the pivot frame to improve pivot sensitivity. This product can also be used in conveyors for both forward and reverse operation.

When the belt comes into contact with the guide roller positioned in front of the pivot axis connecting the upper and lower double-structured frame, the frame pivots within a certain angle range. The resultant force generated at this time, due to the function that returns the belt to the center of the conveyor, allows for adjustments of wandering and misalignment with minimal force applied, reducing the risk of belt damage.

• Conveyor
• roller

This is an automatic centering idler on the return side that uses tapered rollers. Due to the larger diameter in the center of the belt and the smaller diameter at the ends, the difference in surface speed of the rollers during belt contact activates the tracking and offset adjustment function. The frame pivots towards the side where the belt is misaligned, promoting the adjustment function.

• Conveyor
• roller
• Belts and pulleys

Similar to the JAR-T type, the side roller is a tapered return idler. The principle of occurrence for meandering and offset adjustment is the same, but as a structural difference, a pivot axis is arranged at the bottom of each tapered roller support on the left and right, eliminating the pivot frame to improve pivot sensitivity. This product can also be used in conveyors for both forward and reverse operation.

• Conveyor
• roller
• Belts and pulleys

This is a self-aligning idler on the return side, designed to press a tapered roller against the upper surface of the belt within a double-structured frame. It has a high ability to correct wandering due to its ease of conforming to the curling tendency of the return belt.

• Conveyor
• roller
• Belts and pulleys

This is a self-aligning idler on the return side, designed to press a tapered roller against the top surface of the belt within a double-layer frame. It has a high ability to correct wandering due to its ease of following the curling tendency of the return belt.

• Conveyor
• roller
• Belts and pulleys

This is an idler that corrects the wandering of the return side belt using belt tension and frictional force. Since the roller contacts the back surface of the belt, there is no adhesion of transported items to the roller.

• Conveyor
• roller
• Belts and pulleys

Similar to the ARP-2 type, this idler corrects the wandering of the return side belt by utilizing belt tension and friction. Since the roller contacts the back surface of the belt, there is no adhesion of transported items to the roller. Additionally, it can also be used for conveyors with both forward and reverse operation.

• Conveyor
• roller
• Belts and pulleys

This is an idler that corrects the wandering and misalignment of the return side belt using belt tension and frictional force. It features a mechanism where the corrective force increases in proportion to the symptoms. Since it contacts the backside of the belt conveying surface, there is no adhesion of transported items to the roller.
