Technical Specifications at a Glance
Chain Type
No.2060HR SS (2062H SS)
Product Overview
The SUS2060RB is the largest and most powerful sprocket in our stainless steel double-pitch range. Designed for No.2060HR SS (also referenced as No.2062H SS) roller chain, it combines the heavy-series construction of the 2060H chain with the large-roller design (22.23 mm roller diameter, matching No.120 standard chain) that enables track and rail running in overhead and power-and-free conveyor systems.
At 38.10 mm pitch with a 22.23 mm roller, this combination handles the most demanding heavy-duty overhead conveying applications: automotive body-shop overhead trolleys, heavy logistics power-and-free systems, carcass overhead conveyors in large abattoirs, and industrial assembly-line overhead carriers where both load capacity and stainless corrosion resistance are non-negotiable. It replaces Tsubaki 2062H, Renold 2060HR, and equivalent Rexnord heavy-large-roller double-pitch sprockets at factory-direct pricing from Hangzhou.
Dimensional Specifications — SUS2060RB
Full data for all standard tooth counts. Outside diameter and pitch diameter are calculated for the 22.23 mm large roller geometry. Hub bore maximum of 55 mm accommodates the large drive shafts typical of heavy overhead conveyor systems.

Why Choose the Large-Roller Heavy Double-Pitch System?
The 2060HR / 2062H system represents the top of the double-pitch chain performance pyramid. The 22.23 mm roller provides the largest contact patch of any standard double-pitch chain, distributing rail-contact stress across the greatest possible area — which translates directly to longer guide-rail wear life in heavy-loaded overhead conveyor systems. The heavy chain construction provides the highest breaking load in the double-pitch family, supporting unit loads that would overstress lighter double-pitch chains.
In practice, the SUS2060RB / No.2062H system is specified when the conveyor designer needs the noise, inertia, and track-running benefits of double-pitch chain, but at load levels that require the strength of a heavy No.60 chain. If your overhead system currently uses heavy standard-pitch No.60 or No.80 chain and you want to reduce drive noise, consider whether a 2060H / 2062H double-pitch system can deliver the same load capacity more quietly.
Precision Manufacturing & Quality Assurance
1
Material sourcing
Mill-certified 304 stainless billet with traceable heat numbers. Chemical composition verified before production release.
2
CNC hobbing
Tooth form hobbed to JIS B 1802 for 22.23 mm roller geometry. Pitch accuracy maintained across all tooth counts to DIN quality grade 8.
3
Bore machining
H7 bore tolerance on CNC turning centres. Keyway broached or milled to DIN 6885A. Taper-lock-compatible bores available.
4
Passivation
Acid passivation per ASTM A967 restores the chromium-oxide layer after machining, maximising corrosion resistance for wash-down environments.
5
Inspection & packing
Batch dimensional checks, visual inspection, individual VCI anti-rust paper wrap, export carton with desiccant sachets.
Industry Applications
🚗
Automotive Body-Shop Overhead
Power-and-free overhead conveyor systems for vehicle body transport between painting, welding, and assembly stations — some of the most demanding overhead conveyor environments in existence.
🥩
Heavy Abattoir Overhead
Large carcass overhead rails in slaughterhouses require heavy-gauge stainless double-pitch for load capacity, corrosion resistance, and food-hygiene compliance simultaneously.
🏗️
Heavy Industrial Assembly
Overhead carrier systems for large sub-assemblies in machinery, rail vehicle, and aerospace manufacturing facilities where part weight exceeds the capability of lighter chain systems.
❄️
Cold-Store Logistics
Overhead pallet and product carrier systems in blast-freeze and cold-store facilities where sub-zero temperatures and frequent defrost cycles require both corrosion resistance and material toughness.

What Our Customers Say
★★★★★
“We operate a heavy overhead conveyor at our meat-processing plant using SUS2060RB. After one full year of daily operation — including intensive CIP with hot caustic — there is zero visible corrosion on any sprocket. Outstanding product.”
★★★★★
“Replaced Tsubaki 2062H sprockets on an automotive body-shop overhead conveyor. The SUS2060RB fit was exact. We saved approximately 40% per piece compared to the OEM price while getting identical dimensional performance.”
★★★★☆
“Solid quality on the SUS2060RB. We checked tooth form and bore dimensions carefully before installation — matched our Renold 2060HR originals. Only minor comment: we would appreciate express shipping option for urgent maintenance orders.”
Frequently Asked Questions
1. What is the relationship between No.2060HR and No.2062H?+
Both designations refer to the same chain: double-pitch, 38.10 mm pitch, heavy construction, 22.23 mm large roller. No.2060HR is the JIS-standard designation; No.2062H is the ANSI-market designation. The SUS2060RB sprocket mates correctly with both.
2. How does SUS2060RB differ from SUS2060SB?+
The roller diameter is the key difference: SUS2060SB uses a small roller (11.91 mm, same as No.60 chain) while SUS2060RB uses a large roller (22.23 mm, same as No.120 chain). These require different chain types and the tooth form geometry is distinct — they are not interchangeable. Specify which chain type your system uses when ordering.
3. Is 316L available for SUS2060RB?+
Yes. 316L stainless is available for all SUS2060RB configurations. For heavy abattoir, coastal, or chemical-process overhead conveyors where 304 stainless has shown pitting, 316L provides the additional chloride resistance needed. Specify 316L when requesting a quote.
4. Can you supply SUS2060RB with a split hub for maintenance?+
Yes, split-hub configurations are available on request for the larger tooth counts. A split hub allows sprocket replacement without full shaft disassembly — particularly valuable on high-installation overhead conveyors. Contact us with your shaft diameter and space constraints.
5. What is the maximum unit load the No.2062H drive system can handle?+
This depends on chain speed, drive layout, and fatigue factor. No.2062H heavy chain has a breaking load of approximately 95 kN; working load for conveyor applications is typically 10–15% of breaking load at normal speeds. Share your load, speed, and span with our engineering team for an application-specific assessment.
