73LP Chainsaw Chain - 3/8" Pitch .058"/1.5mm Gauge Full-Chisel Saw Chain on Bulk Spool
Professional-Grade 73LP Semi-Chisel / Full-Chisel Saw Chain - 3/8" .058" Bulk Roll for Chainsaw Dealers & OEM Cutting Applications
73LP 3/8 .058"/1.5mm Chain saw chain
The 73LP Chainsaw Chain is a professional-specification saw chain engineered to the 3/8" pitch and .058" (1.5mm) gauge standard, supplied on a large-capacity bulk spool for dealer distribution, OEM chain cutting, and high-volume replacement chain supply. The 73LP designation identifies the chain's drive link count per foot configuration and cutter geometry, making it a widely recognised specification in the professional chainsaw market compatible with a broad range of gasoline and electric chainsaws accepting 3/8" pitch chains. Manufactured from high-carbon chromium steel with precision-ground cutter teeth and hardened rivets, this chain delivers aggressive cutting speed through hardwood and softwood timber while maintaining edge retention across extended cutting cycles. The .058" (1.5mm) gauge drive links are matched to guide bars with a .058" groove width - one of the most common bar gauge specifications across mid-range and professional chainsaw platforms - ensuring correct chain-to-bar fit without shimming or groove modification. Supplied on a bulk spool, the chain can be cut to any required loop length by dealers and repair shops, enabling a single spool to fulfil replacement chain orders across multiple bar lengths and saw models - significantly reducing inventory complexity for parts distributors and equipment dealers.


Technical Profiles & Materials
Case-Hardened Steel Wrist Pin:
1. High-Carbon Chromium Steel Cutters - Precision Ground & Heat Treated The cutting teeth are manufactured from high-carbon chromium steel alloy and individually precision-ground to a consistent cutter geometry before heat treatment. Chromium content increases surface hardness and corrosion resistance compared to plain carbon steel cutters, extending the intervals between required chain sharpening during commercial logging and land-clearing operations. The heat treatment process achieves a cutter hardness that balances aggressive cutting performance with the toughness needed to survive incidental contact with soil, embedded grit, and wire - the most common sources of premature cutter edge damage in field conditions.
2. Hardened Steel Drive Links & Rivets with .058" Gauge Precision The drive links are stamped and hardened to maintain the .058" (1.5mm) gauge dimension within tight tolerance across the full chain length. Dimensional consistency in drive link gauge is critical for correct engagement with the guide bar groove - undersized links cause chain rattling and bar groove wear, while oversized links cause binding and overheating. Hardened rivets connect the link plates with a press-fit that resists lateral play development under the cyclic tensile and bending loads of high-speed chainsaw operation.
3. Bulk Spool Format - Cut-to-Length Dealer Supply Configuration The chain is supplied wound on a rigid green polypropylene spool in bulk roll format, enabling dealers and repair shops to cut custom loop lengths for any bar size from a single spool inventory item. The spool format protects the chain from kinking, tangling, and corrosion during storage and transport. This supply configuration eliminates the per-loop packaging cost of pre-cut chains and enables competitive per-link pricing for high-volume distributors and OEM assembly operations.

Products Application

Professional Logging & Commercial Timber Operations
Commercial logging crews and timber harvesters demand saw chain that maintains aggressive cutting speed through full shifts of heavy hardwood and softwood felling. The 73LP chain's precision-ground full-chisel cutters deliver the fast, clean cut performance that experienced operators expect, while the chromium steel construction extends sharpening intervals - reducing the time lost to chain maintenance during high-volume daily timber production. Bulk spool supply allows logging operations to cut replacement chains on-site to exact loop lengths required for their specific bar and saw combinations.

Firewood Processing & Rural Land Clearing
Landowners, farming operations, and rural property managers processing large volumes of firewood or clearing land of fallen and standing timber benefit from the versatility of the 73LP bulk chain. A single spool supplies replacement chains across multiple chainsaw models operating on the property - eliminating the need to stock separate pre-cut chain SKUs for each saw. The semi-chisel cutter option provides safer operation for less experienced operators while maintaining effective cutting speed through mixed wood types and dirty or grit-contaminated timber.

Chainsaw Parts Dealers & OEM Chain Distributors
For chainsaw parts dealers and saw chain distributors, bulk spool supply of 73LP chain is the most inventory-efficient format available. A single spool covers replacement chain demand across the full range of bar lengths compatible with 3/8" .058" specification - from 12-inch homeowner bars to 36-inch professional bars - without requiring a separate SKU for each loop length. This dramatically reduces warehouse space requirements, simplifies reorder management, and enables competitive per-link pricing that supports healthy dealer margins on one of the highest-turnover chainsaw consumable products.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
