JRC List of Products and Services

The three-roll unit is composed of one press roller and two spiral rollers, which forcibly scrape off attachments on the belt and promote "falling ore."

This is a roller used for V-type pressing return idlers (VRP type).

It is a roller with different diameters on the left and right, used as a side roller for taper-type automatic centering return idlers and taper-type reverse pressure automatic centering return idlers.

This roller improves the wear resistance and corrosion resistance of pipes by bonding rubber to the surface of a steel pipe roller. There are NR type (wrapped with natural rubber) and NBR type (wrapped with nitrile rubber), which has superior oil resistance.

This is a roller with a PVC pipe pressed into the surface of a steel pipe roller. It has excellent corrosion resistance and chemical resistance, making it impervious to most acids, alkalis, and salts, thus maintaining its original performance over a long period. The PVC pipe used is VU pipe.

This is a roller made of hard PVC (VP) that has high chemical resistance, acid resistance, and alkali resistance, and is also excellent in water resistance. It does not transfer odors or colors to materials, is hygienic, and is characterized by being lightweight and durable.

This is a roller used in various guide idlers and Trough-type guide idlers (TG type). The GR type is a general steel pipe roller, while the TGR type is a roller made of wear-resistant ductile cast iron.

This is a roller used for lightweight carrier idlers (LC type).

This is a roller used for lightweight flat carrier idlers (LFCL type, LFCH type).

This is a roller used in lightweight impact idlers (LKC type).

This is a roller used in lightweight return idlers (LR type).

The roller surface, which has a symmetrical spiral shape, has the function of scraping off the "adhesion" of transported items that cause belt wandering and misalignment while rotating. It is recommended to install it in areas within the conveyor system where you want to promote the flow of bulk materials.

It is recommended to install it in areas within the conveyor system where you want to promote the discharge of ore.

This is a roller with a surface coated with soft rubber (smart rubber) with a hardness of 32° t5. Due to its very high rebound elasticity, it prevents sticking of wet materials, high-viscosity materials, and ice to the roller surface, and its excellent wear resistance contributes to reducing the frequency of replacements.

It is a roller with different diameters on the left and right, used as a side roller for taper-type automatic centering return idlers and taper-type reverse pressure automatic centering return idlers.

This is a roller used in the VR type return idler (VR type) of a trough-type VR system.

This is a roller used as a side roller for the A-type pressing return idler.

This is a roller used as a center roller for type A pressed return idler (3-groove offset type).

This is a roller used in lightweight spiral return idlers (LSR type).

This is a roller used for the YC type carrier idler with a two-trough design. The basic specifications are the same as those of a standard carrier roller (type C), but the roller width is longer for the two-trough type.

This is a roller used in the flat carrier idler (JFC type) that is used to transport "bulk items" through skirt rubber, in addition to "voluminous items" such as beer cases, cement bags, and grain bags.

This is a roller used at the idler in areas where transported items fall, such as hoppers and chutes (impact areas) on a conveyor. The groove-shaped impact rubber is bonded to a steel pipe roller, preventing surface delamination and mitigating the impact of the fall.

This is a roller used at the idler in areas where transported items fall, such as hoppers and chutes (impact areas), on a conveyor. The hollow-type impact rubber is bonded to a steel pipe roller, preventing surface peeling and mitigating the impact of the fall.

This is an impact type of flat carrier roller (FC type). It is used in areas where you want to mitigate the impact of falling objects during flat transport. The groove-shaped impact rubber is bonded to a steel pipe roller, eliminating concerns about surface peeling.

It is a roller with different diameters on the left and right, used as a side roller for tapered automatic centering carrier idlers (single-axis and dual-axis).

This is a center roller used for tapered automatic centering carrier idlers (single-axis type) and (dual-axis type).

This is a roller with a surface coated with T5 soft rubber (smart rubber) with a hardness of 32°. Due to its very high rebound elasticity, it prevents sticking of wet materials, high-viscosity materials, and ice to the roller surface, and its excellent wear resistance contributes to reducing the frequency of replacements.

JRC refers to rollers with non-standard dimensions as "B-type rollers," and we can manufacture them as shown in the table below. When making a request, please check the structural drawings of each roller and specify your desired dimensions and specifications. We also accommodate special processing such as threading at the shaft end and pin holes. (Please refer to the example of shaft end processing in the figure below.)

At JRC, we also manufacture "short rollers" used in steep incline conveyors. For roller lengths (L1) of less than 100L, we recommend the TRJ type (straight bushing type). We also accommodate special processing of shaft end shapes. (Please refer to the example of shaft end processing in the figure below.)

This is a steel pipe roller that is most commonly used according to JIS standards. The roller that supports the belt on the carrying side (carrier side) is called a carrier roller.

This is a roller made of steel pipe that is most commonly used according to JIS standards. The roller that supports the return side belt is called a return roller.

This is a roller used in the V-link return idler (JVR type) that connects books with a joint link.

This is a return roller with multiple rubber rings placed on the surface of a steel roller, reducing the contact length with the belt and decreasing the dropping of materials adhering to the belt (material fall-off).

Similar to the sleeve type, this return roller is specialized in reducing the drop of materials adhering to the belt (falling debris) by placing multiple rubber rings on the surface of the iron roller.

This is a roller used in the Garland Carrier Idler (GC type). There is a hole for the joint link at the shaft end.

This is a roller that improves the wear resistance and corrosion resistance of pipes by bonding rubber to the surface of steel pipe rollers. There are NR type (natural rubber wrapped) and NBR type (nitrile rubber wrapped), which has superior oil resistance.

This is a roller with a PVC pipe pressed into the surface of a steel pipe. It has excellent corrosion resistance and chemical resistance, making it unaffected by most acids, alkalis, and salts, thus maintaining its original performance over a long period. The PVC pipe used is a VU pipe.

This is a roller made of hard PVC (VP) that has high chemical resistance, acid resistance, and alkali resistance, as well as excellent water resistance. It does not transfer odors or colors to materials, is hygienic, and is characterized by being lightweight and durable.

Belt conveyor pulleys (hereinafter referred to as "pulleys") are placed in key areas of the belt conveyor. In the event that even one of them is damaged, it could lead to the conveyor stopping, potentially halting the entire system. Additionally, since they are used under harsh conditions that are greatly affected by the belt's tension and winding, careful selection of each component based on solid design principles and high manufacturing skill is required. JRC thoroughly conducts strength calculations based on its own design standards, selects appropriate components, and carries out consistent production at specialized factories to provide safe and highly reliable pulleys.

This is a belt cleaner characterized by a rigid structure that withstands harsh operating environments, powerful scraping that continuously removes any materials adhering to the belt surface, and easy blade replacement. It also features a tension automatic adjustment function that is gentle on the belt.
