Hunan ChengGang Conveyor Machinery Technology builds conveyor idlers, rollers, pulleys, brackets and belt-cleaning components in our own 22,000㎡ plant in Liuyang, Hunan — with 20+ years of manufacturing behind every roller we ship.
ChengRoll is the export brand of Hunan ChengGang Conveyor Machinery Technology Co., Ltd. We are not a trading company: tube cutting, shaft machining, bearing assembly, welding, coating and final inspection all happen inside our own plant, so a drawing you approve is a drawing we build.
Our components are specified to GB, DIN, JIS and BS standards and exceed the requirements of GB/T 10595-2009 in the performance areas that decide service life — runout, rotational resistance, dust ingress and seal retention. Every roller leaves with a traceable ID, and every shipment leaves with inspection records.

We are a long-term qualified supplier to leading equipment makers, steel and power groups, and to the Brazilian mining company Vale. Components are exported to more than 20 countries and regions.
Each line below has its own models, specifications and selection notes. If you are not sure which component fits your system, send us the belt width and duty condition — our engineers will specify it for you.

26 models — troughing, return, impact, self-aligning, spiral, rubber disc, garland, UHMWPE, nylon, HDPE, stainless, heavy-duty and more.

17 constructions — steel cord, EP, PVC, PU, rubber, nylon, chevron, corrugated sidewall, pipe, elevator and ship-loader belts.
Explore belts →
Idler brackets and conveyor frames matched to your trough angle, belt width and load rating, in carbon steel or stainless.
Explore brackets →
Belt cleaners, scrapers, impact beds and buffer beds that protect the belt at the loading point and cut carry-back.

Open resource library →1,000,000 rollers a year from a 22,000㎡ plant with automated lines — tiered capacity expansion for large or repeat orders.
From incoming steel tube to final runout and seal check, with a unique ID tag on every unit so quality stays traceable.
Extreme-environment builds — high temperature, heavy load, corrosive, abrasive — in carbon steel, stainless or composite with rubber/ceramic coating.
Localized service network across 20+ countries with 24/7 technical response, installation drawings and on-site guidance.
Conveyor components fail for boring reasons: wrong seal for the dust, wrong lagging for the belt tension, wrong steel for the climate. Our process is built to catch those before production starts.
Abrasion, rock cuttings, acid/alkali and continuous duty — coated idlers built for millions of load cycles.
Salt-spray corrosion and dynamic balance; overload-tested rollers for continuous shiploader operation.
High-temperature stability to 500 °C with ceramic anti-adhesion coating and ISO 1940 vibration control.
Radiant-heat-resistant assemblies with reinforced shafts and lifecycle ID management.
Carbide-tipped cleaners and negative-pressure dustproof designs for abrasive, dusty sites.
Corrosion-resistant material and coating combinations matched to the process atmosphere.
Issued by ZRIC (Shenzhen Zhongren International Certification), a CNAS-accredited body. The scope covers the production of belt conveyor components — idlers, idler brackets and pulleys. Every certificate number above is publicly verifiable with the issuing body. 7 patents and 100+ industry honours.
Send us belt width, duty condition and quantity. Our engineers will specify the right idler or pulley and quote within 24 hours.
