Say Goodbye to V-Jewel Bearings with Screw V-Jewel Bearings

Jewel bearings are an essential component in high precision instruments such as watches, gyroscopes, and acceleration sensors. But, have you ever heard of a screw v-jewel bearing? If not, then you are in for a treat. In this blog post, we’ll provide an in-depth overview of screw v-jewel bearings and explore how replacing traditional v-jewel bearings with screw v-jewel bearings can increase your instrument’s accuracy and reduce friction. This cost-efficient solution is gaining popularity in the industry and we want to share with you why.

To understand the benefits of screw v-jewel bearings, let's first look at how a conventional v-jewel bearing works. A v-jewel bearing consists of two sections, a pivot and bearing bush. The pivot's tip is shaped like a v and sits atop a jewel bearing bush that has a groove to accommodate the pivot. The pivot sits inside the groove and rotates inside the bush making contact with the jewel and seating the pivot within the bush. The bearing rotates against the jewel bearing, which provides a smooth and low-friction surface for the instrument to function accurately. However, many issues arise with v-jewel bearings. For example, if the pivot drops too deep within the bearing, it will cause friction, inconsistent accuracy, and wear on the bearing surface, leading to inaccuracies in measurement.

Screw v-jewel bearings solve many of these problems by adopting a screw mechanism to adjust the pivot's vertical position within the bearing. The screw allows the pivot's position to be adjusted accurately, which means that the bearing will not experience any friction, thereby increasing the instrument's accuracy. Additionally, screw adjustments make this mechanism more portable and durable. Screw v-jewel bearings have a longer lifespan than traditional v-jewel bearings because the pivot's adjustment screw helps maintain its correct position within the bearing. 

The screw adjustment system allows for easier pivot positioning and quick fine-tuning, which significantly reduces production time. Since screw v-jewel bearings require fewer labor hours compared to the traditional v-jewel bearings, they offer a cost-efficient solution for manufacturers. Additionally, thread adjustments provide durability, making it an ideal solution for industries where rugged and tough applications are common.

Replacing traditional v-jewel bearings with screw v-jewel bearings doesn’t require extensive mechanical training or technical skills. The retrofit process is quite simple; just follow the steps and techniques provided by the manufacturer. Screw v-jewel bearings are a drop-in replacement suitable for almost any machine with traditional v-jewel bearings. Therefore, retrofitting is easy.
