Product Description:

The 0125916-005 Ratchet Drive is manufactured by Danaher. The drive is designed for clockwise rotation with a left shaft. The ratchet drive is designed to provide precise count increments with each drive shaft actuation. The ratchet drive operates through a 36° to 60° arc, delivering an efficient internal return spring mechanism. It is suitable for applications in industrial automation and other precise counting systems.

The 0125916-005 Ratchet Drive includes six cumulative pictures (0.188” (4.78mm) high by 0.156” (3.96mm) wide) in the figures are white on a black background, so they can be clearly seen. Reset is manual, only requiring a knob to operate it. It does not require lubrication, which is required internally. The drive mounts to a base so it may be fairly well held. The case is made of Zamak, the wheels and pinions are made of acetal resin, and the shafts are chrome-plated steel rods with brass gears. Ratchet drives offer faster and more efficient tightening and loosening of fasteners, particularly in narrow spaces, as they allow continuous rotation without repositioning the tool. Other benefits include greater mobility with different-sized sockets, better user comfort and ergonomics due to less strain, and increased durability for long-term usage.

The 0125916-005 Ratchet Drive is consistent with specifications that include improved operational reliability as well. It includes a max travel limited mechanism to prevent over-travel. Essentially, this will perform consistently. The maximum travel potential of the drive mechanism is limited by an internal return spring. It weighs 9oz. (255g). Ratchet drives are used in a variety of applications, including hand tools like socket wrenches for tightening and loosening nuts and bolts in tight locations, and machinery like winches, hoists, and jacks to prevent reverse motion and hold weights.

Frequently Asked Questions about 0125916-005:

Q: Does the 0125916-005 Ratchet Drive require lubrication for smooth operation?

A: No, lubrication is not required for the 0125916-005 Ratchet Drive. Its components are designed to function smoothly without the need for additional lubrication, simplifying maintenance and reducing operational costs.

Q: How does the internal return spring benefit the 0125916-005 Ratchet Drive?

A: The internal return spring ensures the ratchet drive returns to its initial position after each cycle. This feature supports consistent, reliable operation and prevents over-travel or mechanical failure during use.

Q: What is the purpose of the maximum torque specification in the 0125916-005 Ratchet Drive?

A: The maximum torque of 2 oz-in prevents excessive force from being applied to the mechanism. This ensures smooth operation and reduces wear on internal components, improving the lifespan of the drive.

Q: Why is acetal resin used for the wheels and pinions in the 0125916-005 Ratchet Drive?

A: Acetal resin is used for the wheels and pinions because of its durability, low friction, and resistance to wear. These qualities contribute to smooth, long-lasting performance in the ratchet drive mechanism.

Q: How does the Zamak case construction affect the 0125916-005 Ratchet Drive's performance?

A: The Zamak case provides strong, durable protection for the internal components. It helps prevent damage from external impacts while maintaining the drive's structural integrity during operation.
