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.

HR = Heavy Roller (22.23 mm): No.2060HR chain uses a 22.23 mm roller diameter — the largest in the standard double-pitch stainless family. The SUS2060RB hob is specifically profiled for this roller. Using any other tool produces incorrect engagement geometry and rapid wear. Do not substitute SUS2060SB tooling.

Manufacturing Precision for Heavy-Roller Geometry

01
📦 Heavy-Blank Turning — Stainless Control

304 stainless bar up to ~100 mm diameter for the largest SUS2060RB sizes. High-feed turning with continuous coolant prevents work hardening. Single-clamping for bore-to-OD concentricity ≤ 0.02 mm on all four tooth counts.

02
⚙️ CNC Hobbing — 22.23 mm Heavy-Roller Tool

Dedicated No.2060HR hob for the 22.23 mm roller geometry. Integer tooth-count synchronisation programmed for the 38.10 mm double-pitch circle. First-off PCD CMM measurement before production; tolerance ±0.05 mm.

03
🔑 Bore, Keyway & CMM Final Check

Bore to H7 (Ra ≤ 0.8 μm). DIN 6885 keyway on request. CMM measures PCD, bore diameter, and hub runout on every finished part. Conforming parts laser-marked and packed in VCI wrap for export.

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.

Frequently Asked Questions

1. Can SUS2060RB engage standard No.2060 or No.2060HS chain?+
The SUS2060RB is designed specifically for No.2060HR chain with its 22.23 mm heavy roller. Standard No.2060 and No.2060HS chains use an 11.91 mm roller — a completely different geometry. A SUS2060RB sprocket will not correctly engage these chains; the tooth root is sized for the 22.23 mm heavy roller, not the 11.91 mm standard roller. Always verify chain roller diameter matches sprocket hob specification before ordering.
2. What distinguishes No.2060HR from No.2060HS?+
No.2060HS (heavy series) refers to upgraded link plates and pins at the same 11.91 mm roller diameter. No.2060HR (heavy roller) upgrades the roller diameter itself to 22.23 mm, producing a physically different chain engagement geometry. These are two distinct chain products requiring different sprockets. SUS2060SB/RB is for HS; SUS2060RB is for HR.
3. Is 316 stainless available for the SUS2060RB?+
Yes — 316-grade stainless (EN 1.4401 with molybdenum addition) is available as a custom material for seawater, brine, and high-chloride process applications. Specify at inquiry stage. Material cost and lead time differ slightly from standard 304.
4. What is the maximum bore for SUS2060RB?+
All four tooth counts share a maximum bore of 55 mm with hub BD 83 mm and BL 45 mm. This covers the shaft diameters typically encountered in heavy double-pitch conveyor drives at the 38.10 mm pitch class.
5. How does SUS2060RB compare to SUS2060SB in conveyor applications?+
SUS2060SB uses No.2060HS chain with 11.91 mm rollers and delivers good capacity for most large conveyor requirements. SUS2060RB uses No.2060HR chain with 22.23 mm heavy rollers and delivers higher working load capacity for the most demanding heavy industrial conveyor applications. Choose SUS2060RB when load calculations show the SUS2060SB running above 70% of rated chain capacity at your conveyor speed.
