Product Overview
The SUS2060SB is the largest small-roller double-pitch stainless steel sprocket in our standard range, designed for No.2060H SS chain running at 38.10 mm pitch. At this pitch, double-pitch chain drives transition from light-to-medium conveying into genuinely heavy conveyor service — pallet conveyors, heavy tote-bin systems, timber off-feed equipment, and bulk-product handling lines all utilise the No.2060H double-pitch chain where standard No.60 chain noise and weight would be a drawback.
Produced in 304-grade stainless steel by CNC hobbing in our Hangzhou factory, the SUS2060SB covers 9½ through 12½ effective teeth — enough range to serve most standard and overdrive conveyor speed ratios at this pitch. It substitutes directly for Tsubaki 2060H, Renold heavy-series double-pitch 60 stainless, and equivalent Rexnord 2060-type components at factory-direct pricing.

Heavy-Duty Double-Pitch Performance
No.2060H chain earns the “H” designation for its heavier-than-standard construction — increased side plate thickness and pin diameter give it a breaking load substantially above the non-heavy 2060 chain. The SUS2060SB sprocket is dimensioned to match this heavier chain geometry, with a 11.7 mm tooth width that correctly seats the wider side plates without interference.
1
Chain seating geometry
Tooth form hobbed to JIS B 1802 for No.2060H roller diameter (11.91 mm). Gullet radius and approach angle are optimised for smooth roller entry at heavy-conveyor chain speeds.
2
Hub strength
Hub diameter and length are sized for the torque levels typical of No.2060H drive applications — significantly larger than equivalent 2040 or 2050 hubs.
3
Bore capacity
Maximum bore of 55 mm on a 12½T sprocket accommodates large conveyor drive shafts common in heavy industrial and food-processing machinery.
4
Surface finish
Passivated 304 SS withstands the aggressive daily wash-down chemicals used in food-grade heavy conveying environments — bleach, caustic soda, and acidic rinses.
5
Inspection
Batch-level dimensional verification and 100% visual inspection before packing. Material certificates available.
Industry Applications
📦
Pallet & Tote Conveyors
Heavy unit-load conveying in distribution centres, breweries, and food manufacturing facilities specifying double-pitch for noise reduction.
🍗
Poultry & Meat Processing
Overhead trolley and carcass-conveyor systems need heavy-gauge stainless double-pitch drives to handle product weight in wash-down areas.
🪵
Timber & Board Handling
Off-feed and stacking conveyors in sawmill and panel-board operations often use No.2060H chain for its load capacity at long conveyor spans.
🏗️
Industrial Assembly Lines
Overhead electrified monorails and power-and-free conveyor systems in automotive or heavy manufacturing plants utilise this pitch for quiet, high-load operation.

What Our Customers Say
★★★★★
“We use SUS2060SB on overhead pallet conveyors in our frozen food facility. Runs in −25 °C cold-store conditions with daily CIP. Eight months in and there is zero corrosion or tooth wear visible. Excellent product.”
★★★★★
“Direct substitute for our Tsubaki 2060H sprockets. Ordered 14 pieces with 45 mm bores, all arrived correctly machined. Our maintenance engineer confirmed the fit was perfect first try.”
★★★★☆
“Good quality, competitive price, and reliable lead time. We have been ordering from Ever-Power for six months and quality is consistent across batches — which is what matters for our production schedule.”
Frequently Asked Questions
1. What does the “H” in No.2060H mean?+
“H” stands for heavy — the No.2060H chain has thicker side plates and a larger pin diameter than standard No.2060 chain, giving it a higher breaking load and longer fatigue life under heavy conveying loads. Always ensure your sprocket is specified for the H-series chain if that is what your conveyor uses.
2. Is SUS2060SB compatible with No.2060 (non-heavy) chain?+
The pitch and roller diameter are the same, so mechanical engagement works. However, the non-heavy chain has narrower side plates, so there will be additional lateral clearance at the tooth. For best performance, match chain and sprocket series — use No.2060H chain with SUS2060SB.
3. Can SUS2060SB be supplied with a split hub for maintenance access?+
Yes, split-hub configurations are available for large-bore sizes on request. A split hub allows the sprocket to be removed from the shaft without dismantling the conveyor structure — valuable in overhead or confined-space installations.
4. What is the maximum operating temperature for 304 stainless steel sprockets?+
304 stainless retains its corrosion resistance and structural properties continuously up to approximately 300 °C and intermittently up to 870 °C. For oven or dryer conveyor applications, confirm the actual chain temperature with our engineering team before ordering.
5. Do you offer annual supply contracts for maintenance programmes?+
Yes. We offer blanket-order agreements with scheduled call-offs at fixed unit prices for customers with predictable annual consumption. Contact
[email protected] with your estimated annual usage for a supply agreement proposal.
