1610 Taper Lock Bushings

The 1610 Tapered Locking Bushing has a 20mm hole and is designed to fit any tapered locking pulley or pulley. These bushings are precision machined to tight tolerances and are available in a variety of sizes and materials. In addition to high-quality design and durability, the 1610 Tapered Locking Bushings are also available in metric sizes.
Manufactured to precise tolerances, this line of bushings is designed for power transmission applications. Each bushing has a cap screw for extra security. We carry these bushings and many others in a wide range of materials. These products are an excellent choice for your next power transmission project. They come in a variety of sizes, including 1” and 2” holes.

1. Clean all oil, dirt, and paint from the shaft, bushing holes, bushing exterior, and bores of components (sprockets, pulleys, etc.).
2. Insert the bushing into the assembly. Match hole patterns, not threaded holes (each hole is threaded on 1 side only).
3. Thread the set screw or cap screw into the half-threaded hole shown below. Install the assembly on the shaft.
4. Alternately set the torque setting or cap screw* to the recommended torque setting in the table below.
5. Fill all unoccupied holes with grease.


1. Remove any retaining or cap screws.
2. Insert the set screw or cap screw into the above hole.
3. To reinstall, complete all 5 (5) installation instructions.

In terms of insulation, the W-sleeve consists of 2 layers. The outermost layer consists of porcelain. The innermost insulation system consists of concentric capacitors. The outermost layer consists of several layers and is used for electrical testing. Although this is a solid insulation system, it requires extensive metal fittings and flexible seals. It is recommended for voltages of 26 kV or lower.
Changes in PF indicate that moisture has penetrated and degraded the casing. Also, if the PF value doubles, the bushing needs to be replaced. Another degradation indicator is the change in capacitance, measured in milligrams (pF). A 10% increase from its nameplate value indicates that the bushing needs to be replaced. So, what are the symptoms of a damaged W bushing?
Hot Loop Test: This test is performed on the bushing to evaluate its ability to conduct current. Using a conductive ring around the porcelain, the test can determine if the dielectric loss has occurred through the sleeve. It can also detect cracked porcelain, deteriorated cement joints, gasket leaks, and faults within the condenser layers. Additionally, this test checks the oil level in the oil-filled bushing.
