TGL Nylon Replacement Coupling Sleeves, S32/S38/S42/S48/S65

TGL Nylon Replacement Coupling Sleeves

Replacement internally toothed nylon sleeves for selected TGL S-series configurations. This listing supplies the selected nylon sleeve only. Steel hubs, shaft bores, keyways, keys, set screws and complete coupling assemblies are not included. The isolated-sleeve family photographs illustrate the construction; they are not independently verified photographs of every selected tooth count or an indication of pack quantity.

Selected Sleeve Specifications

Outside diameters and tooth counts below follow the exact source SKU labels. Inch equivalents are rounded to three decimal places.

Compatibility Checks

Match the sleeve model, outside diameter, internal tooth count, tooth profile and mating-hub dimensions. Outside diameter or a similar-looking sleeve alone does not prove compatibility. Sleeve width, inside tip/root diameters, tooth module, allowable misalignment and operating clearances are not independently specified in the supplied sleeve data. No interchangeability with the existing NL series or another manufacturer's coupling is claimed.

Material and Operating Limits

The source describes the part as nylon. Exact polymer grade, reinforcement content, hardness and tested material properties are not supplied. Assembly-level temperature, torque, speed, maintenance and certification claims are not transferred to these replacement sleeves. Confirm the required operating conditions for the selected sleeve and complete drive before use.

Installation and Inspection

Isolate the drive before removing the existing sleeve. Inspect the matched steel hubs and their teeth for wear, damage and alignment. Compare the old sleeve's dimensions and tooth geometry with the selected replacement. Do not force an incompatible sleeve onto the hubs. Check seating and clearance, then test the complete assembly in accordance with the equipment's requirements.

Original Photographs and Supply Scope

The following original photographs show isolated nylon sleeves and their arrangement with steel hubs. Assembly pictures are included for context, not as a promise that hubs or fasteners are supplied. Product geometry and the original component callout lines are retained. Chinese captions are translated into English. Supplier logos, invoice promotions, unverified certification and absolute performance claims are excluded.
