PR-15.875-2300-1-67

Torque transmission through PR-15.875-2300-1-67

In operation, the chain transfers rotational movement from one drive element to another. The rollers engage with the sprocket teeth, while the plates and pins carry the tensile load. This type of chain is used where a fixed mechanical connection is required without changing the transmission principle. The chain does not regulate speed and does not compensate for incorrect alignment by itself. Correct tension, sprocket condition, lubrication, and installation length are all part of normal service checks.

Tail rotor drive work with PR-15.875-2300-1-67 installed

The PR-15.875-2300-1-67 operates as part of the helicopter tail rotor drive system. In that position, the chain helps maintain synchronized rotation between transmission elements under changing load. If the drive shows noise, uneven movement, or abnormal wear, the chain is only one part of the inspection. Maintenance should also include sprockets, shafts, bearings, chain tension, lubrication condition, and the surrounding drive housing. A new chain installed on worn sprockets may not give the expected service result.

Mi-8 aircraft application of chain PR-15.875-2300-1-67

The chain is used on Mi-8 family helicopters as a tail rotor drive chain. Open supplier listings identify the item as PR-15.875-2300-1-67 / ПР-15,875-2300-1-67 and describe it for the Mi-8 tail rotor drive. The base chain designation PR-15.875-2300-1 refers to a single-row precision roller chain, while the final “67” identifies the fixed link count used for the aircraft application. For supply, the exact aircraft catalog reference should be checked before ordering.

Identification and ordering checks for PR-15.875-2300-1-67

Before ordering, the chain designation should be compared with the helicopter parts catalog and product documentation. The product may appear as PR-15.875-2300-1-67, PR-15875-2300-1-67, or PR-15.875-2300-1 in shortened form. The link count matters and should not be omitted when ordering the aircraft drive chain. A clear request should include the helicopter type, drive system location, full designation, and documentation requirement. The product is also known under alternative designation ПР-15,875-2300-1-67.
