Import 150 Dobby Chain Sleeve — Buy in Bulk from Supplier in China

The 150 dobby chain sleeve is a precision-engineered wear component for dobby weaving machines, designed to guide and protect the chain mechanism that controls the heald frames. This sleeve is manufactured to ensure smooth chain travel, reduce friction, and minimize operational noise in high-speed textile looms. Its core function is to maintain consistent chain alignment, which directly impacts weaving precision and fabric quality.

Typically produced from durable, abrasion-resistant materials such as case-hardened steel or specialized polymer composites, these sleeves are built to withstand continuous friction and temperature fluctuations in a mill environment. The '150' designation commonly refers to a standard size or compatibility class within dobby systems. Industry-standard tolerances for such sleeves are tight, often within ±0.05mm, to ensure proper fit and function. They are usually supplied as a direct replacement part, matching the original equipment manufacturer's specifications for popular dobby models.

Textile mills and weaving workshops are the primary buyers, sourcing these sleeves as critical spare parts to maintain loom uptime and prevent costly production halts. When sourcing from Zhejiang Dongbin Rubber Machine Screw Co., Ltd. in Zhoushan, China, buyers should confirm the exact compatible dobby machine models, the material grade, and the hardness rating. The supplier's location in the Shantan Industry Zone suggests access to established metalworking and precision manufacturing infrastructure, which is relevant for verifying production capabilities.

Zhejiang Dongbin Rubber Machine Screw Co., Ltd. is based in the Shantan Industry Zone, Dinghai District, Zhoushan, Zhejiang, China. The company's name indicates a specialization in rubber processing machine screws, which suggests a core competency in precision metal component manufacturing. This background is directly relevant to producing durable textile machinery parts like the dobby chain sleeve.

The supplier's profile tier is listed as 'imported' with a 'harbor' trust level, and the response rate data is currently at zero. This means there is no verified performance history for response time on this platform. Buyers should initiate direct contact to assess communication reliability and request specific documentation, such as material certifications or quality control reports, before placing an order.
