Model codes are configuration references. Final mount, length, gauge and matching drive-link count must be approved for the actual equipment.
.325″ Bar Construction for Professional Cutting
Precision groove machining, rail treatment and controlled heat treatment support stable chain guidance. The range is intended for medium-power professional saws used in forestry, logging, tree cutting and general wood processing. A .325-inch chain must match the selected groove and nose arrangement.
The specification table lists 62Si2Mn silicon-manganese alloy steel; 60Si2Mn spring steel is also described in the construction features. Specify the required grade on the order for the actual model. Retaining both designations makes the material choice explicit rather than replacing a defined grade with an unspecified steel placeholder.
16-, 18- and 20-Inch Configuration Details
The 16-inch models are 325(063)-G1662-11P-4L at .063 inch / 62 DL, 325(058)-E1664-10P-4L at .058 inch / 64 DL, and 325(058)-E1666-12P-4L at .058 inch / 66 DL. The last entry retains the Husqvarna CS4510 application reference as listed for technical checking.
The 18-inch chart gives 325(063)-G1868-1P-4L at 68 DL and 325(058)-E1872-10P-4L at 72 DL. The 20-inch 325(058)-E2076-12P-6L requires 76 DL. Mount and nose differences explain why a length alone cannot establish the loop count or gauge.
STIHL, Husqvarna and Echo Bar References
General equipment references include STIHL MS231 / MS251 / MS261 / MS271 / MS291, Husqvarna 445 / 450 / 455 Rancher / 460 / 550XP and Echo CS-400 / CS-590. The detailed table also includes MS251 and 52 cc / 58 cc application entries. Preserve these as references, not universal fitment guarantees.
Before replacing a bar, compare the mounting slot, oil holes and tensioner interface. Then check the selected .050-, .058- or .063-inch groove and required chain count. An apparently similar .325-inch bar can have a different mount or require a different loop.
OEM Replacement-Bar Purchasing
Custom length, logo, packaging and wholesale quantities can be specified for a distributor or chainsaw brand. Provide the complete model or mounting drawing and the required rail and nose configuration. A packaging or branding request does not establish engineering compatibility.
For matched bar-and-chain sets, record gauge and DL count for each model separately. The detailed chart preserves all application fields, so a buyer can compare individual 16-, 18- and 20-inch configurations rather than receiving only a broad length-range statement.
Buyer Questions about .325″ Chainsaw Guide Bar
What chain fits a .325-inch guide bar?
Use the approved .325-inch chain with the exact groove gauge and drive-link count for the selected model. The range includes .050, .058 and .063-inch options. Bar mount and nose configuration must also match the equipment.
Which lengths are individually listed?
The chart lists 16-, 18- and 20-inch models, within the broader 12–24-inch range. The counts are 62, 64, 66, 68, 72 and 76 DL. Use the full model code to select gauge and count rather than assuming all bars of one length are identical.
Is this bar range intended for professional work?
Forestry, logging, firewood and professional maintenance are listed applications. Suitability for one saw still requires the correct mount, pitch, gauge, nose and chain count. Confirm the material grade and any custom requirements on the ordered model.
