Inventor & General Manager: Feng Jian (冯健)
This profile is one of four CNIPA design patents granted to Dezhou Jiasheng Rubber And Plastic Products Co., Ltd. in 2019. Mr. Feng is named as the sole designer on all four patent certificates.
Overview
When two parallel roller chains share a single rail (carrier chains, accumulation conveyors, parallel-drive lines), the T2 patented profile integrates two precision pockets at standardised centres on a single UHMWPE base.
Design Principle
The T2 profile machines two parallel chain pockets on a wider base (35-50 mm typical), maintaining precise inter-chain spacing — critical for product carriers that span both chains. Eliminates the alignment errors of two separate single-row guides.

Real-World Applications
Bottle carrier conveyors
Two parallel chains carry shared pucks or bottle nests — T2 guarantees that both chains sit at identical heights so the carrier remains level under load.
Heavy-duty pallet accumulation
Pallet handling on double-strand chain benefits from T2's integrated double pocket, which eliminates the cumulative tolerance error of paired single-row guides.
Tyre & rubber processing
Curing carrier lines with twin-strand chains use T2 for hot environments and heavy loads.
Lumber & panel conveying
Sawmill outfeed and panel transfer lines with parallel chain rails benefit from T2's wide stable base, which resists tipping under offset loads.
Automotive carrier lines
Powertrain assembly carriers riding on twin chains use T2 for repeatable carrier position and silent operation.
Why a Patented UHMWPE Profile vs Alternatives
| Solution | Engineering Performance Summary |
|---|---|
| UHMWPE patented profile (our solution) | Self-lubricating · 0.10-0.15 friction · Silent · 25,000-40,000 hr life · No grease · -50 to +80 °C |
| Generic UHMWPE flat strip | No chain pocket, requires external chain guides → assembly complexity, alignment errors |
| Steel side rails (greased) | Requires daily / weekly lubrication · 0.20-0.30 friction · Noisy · 5,000-8,000 hr life · Oil contamination · Energy +10 % |
| Stainless-steel side rails | 5-10× cost · Same friction issues · Heavier · Used only when hygiene mandates exclude polymer (rare) |
| PA6 cast nylon profile | Higher temperature (+120 °C) but absorbs moisture (swells), 2× friction of UHMWPE, shorter wear life |
| Phenolic / paper laminate | Brittle under impact, cannot absorb chain slap, obsolete technology in modern conveyor design |
Material — Verified 8.62 Million Mw UHMWPE
All patented profiles are machined from our in-house UHMWPE compound with verified molecular weight of 8.62 × 10⁶ Da (CTIC report no. CTICAAD39240944050802BR, ISO 1628-3 method). This molecular weight is at the high end of commercial UHMWPE grades and delivers the abrasion resistance, impact strength and low coefficient of friction that the patented geometry was designed to exploit.
- Tensile strength 32.8 MPa (SGS report TJIN2007009852MR_CN)
- Elongation at break 240 %
- Coefficient of friction (dry) 0.10 – 0.15
- Compressive yield ~ 22 MPa
- Service temperature -50 °C to +80 °C continuous
- FDA compliance 21 CFR 177.1520 (CTB220513031CX)
- RoHS 2011/65/EU 26-substance scan, all below detection (SCT-20141027-036N)
Frequently Asked Engineering Questions
What chain centres are standard for the T2 profile?
Standard inter-chain centres are 35, 50, and 65 mm. Custom centres machined to your DWG within 20-30 days.
What chain pitches does T2 support?
T2 is stocked for 08B-2 (12.7 mm) through 16B-2 (25.4 mm) duplex chains. Larger pitches (20B-2, 24B-2) machined to order.
Can I mix chain types on a T2 profile?
The two pockets can be machined to different sizes (e.g. 12B-1 + 10B-1) for asymmetric drive systems. Specify both chain specs in your quote.
How does T2 compare to two separate single-row guides?
T2 eliminates the cumulative tolerance error of paired mounting — the two pockets are machined in one CNC setup so chain-to-chain parallelism is held to ±0.1 mm over 6 metres. Two separate guides typically accumulate ±0.5-1.0 mm of error after mounting.
Is T2 heavier / bulkier than two single-row guides?
Roughly equal in material volume, but T2 occupies less space (one rail vs two) and installs in half the time (one mounting line, half the bolts).
What overall heights are available?
15 / 20 / 25 / 30 / 35 mm standard. Higher profiles available for deep chain pockets on large pitches.
Patent reference and inventor?
CNIPA design patent ZL 2019 3 0404443.0, certificate no. 5555555, inventor Feng Jian (冯健), granted 2019, valid through 2029.
FDA / food-grade availability?
Yes — natural-colour FDA UHMWPE is the default stock material.
Lead time and MOQ?
7-15 days for stock profiles · 20-30 days for custom CNC. 1 piece for stock SKUs · 50 pieces for custom CNC.
Can you ship to my country?
FOB Qingdao · 80+ countries · 4 continents. Most common ports: Hamburg, Antwerp, Long Beach, Santos, Veracruz, Felixstowe, Gdańsk.
