Description
Double Pitch Stainless Steel
Sprockets SUS2060RB
Maximum-capacity large-roller double-pitch stainless sprockets — the heaviest standard RB-type in the SUS range, delivering top-tier load performance with full 304 stainless corrosion immunity.

SUS2060RB — Maximum-Capacity Heavy-Roller Double-Pitch Stainless
The SUS2060RB is the largest-capacity member of the RB-type double-pitch stainless sprocket family. It drives No.2060HR chain — a heavy-roller variant of the 38.10 mm double-pitch chain series, where ‘HR’ designates the heavy roller (22.23 mm diameter). This roller dimension surpasses both the standard No.60 chain roller (11.91 mm) and the No.80 chain roller (15.88 mm), placing the SUS2060RB in a class of its own for load capacity within the double-pitch stainless range. For heavy conveyor systems where neither the SUS2060SB nor the SUS2050RB provides adequate capacity, the SUS2060RB with No.2060HR chain delivers the required working load at the double-pitch architecture’s weight-saving chain spacing.
At 3.10 kg for the 13T version, the SUS2060RB is the heaviest double-pitch stainless sprocket in the standard range. The 22.23 mm roller diameter exceeds the internal chain width (12.70 mm) by a significant margin — the ratio Dr/W = 1.75 — producing a deeply cradling tooth root geometry that distributes high chain tensions across a wide root contact area. This geometry is unique to the SUS2060RB within the stainless double-pitch family and requires dedicated 22.23 mm roller hobbing tooling. All four tooth counts (10T–13T) share the same hub BD (83 mm), BL (45 mm), and maximum bore (55 mm), consistent with the SUS2060SB at this pitch class.
Hangzhou Ever-Power maintains the full double-pitch RB series — SUS2040RB, SUS2050RB, and SUS2060RB — as permanent production items. The No.2060HR hob and CNC programs for all four SUS2060RB tooth counts are in the active production library, allowing orders to proceed without tooling procurement delays. Custom bore, keyway, extended hub, and 316 stainless options are available. As a stainless steel sprocket specialist with over two decades of export experience, we provide the technical documentation and dimensional traceability that regulated industries require.

Manufacturing Precision for Heavy-Roller Geometry
Industry Applications
Large-Scale Heavy Industrial Conveyors
Sugar mills, industrial grain elevators, and heavy bulk material handling plants operating at high loads over long conveyor spans. SUS2060RB handles the heaviest double-pitch drive requirements while stainless construction survives the washdown and process conditions of these facilities.
Chemical Bulk Handling
Drum and bulk bag conveyors in large chemical plants carrying dense product at loads that exceed SUS2050RB capacity. The 22.23 mm heavy roller chain provides the structural margin needed at the top of the double-pitch load range.
Water Treatment Heavy Drives
Heavy sludge thickener drives, large bar screen mechanisms, and primary settling clarifier chains at major treatment works. Heavy-roller stainless drives eliminate the corrosion and capacity issues that affect carbon steel drives in these permanently wet environments.
Mining Wet Zone Conveyors
Underground wet-heading ore conveyors and mineral wash plant drives where heavy loads and aggressive ground water combine. SUS2060RB covers the load-and-corrosion requirement that defines this application class.
Pulp & Paper Chip Conveyors
Chip and wood fibre handling conveyors in paper mills combine heavy load with bleach and white water exposure. Heavy-roller stainless drives outlast carbon steel alternatives in these environments by eliminating the corrosion failure mode.
Heavy Marine Cargo Handling
Shipboard cargo chain drives, fish meal conveyor systems on processing vessels, and port bulk-handling equipment combining heavy loads with salt atmosphere. SUS2060RB eliminates the corrosion maintenance cycle while delivering the capacity required.
