Import Bascolin Nozzle 105015-6150, Dlla150sn615 — Buy in wholesale FOB from Supplier in China

The Bascolin Nozzle 105015-6150, designated DLLA150SN615, is a conventional (mechanical) diesel injector nozzle designed for pump-line-nozzle or in-line pump fuel injection systems rather than modern common rail architecture. Manufactured by China Balin Power Co., Ltd. in Putian, Fujian, this nozzle follows the SN (single spring, normal diameter) series convention, where 150 denotes the nominal spray angle and 615 identifies the specific flow and geometry variant. The 105015-6150 part number aligns with Denso legacy numbering for aftermarket replacement applications in commercial diesel engines, particularly Japanese-origin truck and bus engines from the 1990s-2000s era.

The SN series nozzles typically feature a single-spring valve opening mechanism with a sac-less or mini-sac hole-type tip, depending on the specific application and emissions target. The spray hole count for this nozzle family commonly ranges from 4 to 6 holes, with hole diameters of 0.20-0.28 mm depending on the engine displacement and power density target. Operating pressures are substantially lower than common rail systems, typically 180-220 bar at the nozzle tip, with opening pressures set by shim adjustment during calibration. The nozzle body and needle are conventionally manufactured from alloy tool steel with nitrided or chrome-plated surfaces for wear resistance, rather than the tungsten carbide needle tips seen in high-pressure common rail designs.

This nozzle serves the aftermarket repair and engine rebuild sector for legacy commercial vehicles, agricultural machinery, and stationary diesel engines still operating on mechanical injection systems. Target buyers include diesel injection workshops, heavy equipment rebuilders, and parts distributors in markets where older vehicle fleets remain in service. The DLLA150SN615 cross-references to applications where the 105015-6150 Denso number was originally specified. When sourcing from China Balin Power Co., Ltd., confirm whether the nozzle is supplied with calibration shims, the exact engine models supported, and whether the supplier provides opening pressure setting data. The listing does not state MOQ, price, or lead time, all of which require direct supplier confirmation.

China Balin Power Co., Ltd. is based in Hualin Industrial Zone, Putian, Fujian Province, China. The supplier profile indicates a harbor trust tier with no response rate or response time data currently recorded, meaning prospective buyers have no platform-verified communication history to assess reliability. The company address provided includes full postal detail (351100), which supports due diligence for site visits or third-party factory audits. No information is available on year of establishment, registered capital, or number of employees.

The company's product focus spans fuel injection system components for both legacy mechanical and modern electronic diesel systems. Their catalogue explicitly lists the DLLA150SN615 alongside numerous SN-series counterparts including DLLA150SN555, DLLA160SN564, and DLLA154SN625, indicating maintained tooling for this older nozzle family. Other product lines include head rotors, plungers, delivery valves, common rail valves, and repair kits. The profile does not claim any OEM approvals, ISO certifications, or specific client relationships. Buyers should independently verify manufacturing capability for the SN series, as maintaining precision grinding and lapping equipment for declining-volume legacy products requires different factory investment than high-volume common rail production.
