A U-shaped snap ring is a type of retaining ring that features a U-shaped design. It is used to secure components onto shafts or inside bores, preventing lateral movement or displacement. The U-shape allows for flexibility and easy installation or removal, making it a popular choice in various mechanical applications where securing components without the use of fasteners or adhesives is essential.

The inner diameter of the U-shaped snap ring is the outer diameter of the wear-resistant tile plus the thickness of the wear-resistant tile, and the length varies from 20mm to 70mm. It will be 5mm more in semicircle. The extra part during installation will hold the wear-resistant tile and then spot weld. Compared with the butt-type semicircular snap ring, it is stronger after holding the wear-resistant tile and welding.

Design:

The U-shaped profile provides a spring-like action that allows the snap ring to compress when installed and expand to secure the component in place.

Unlike standard round snap rings, the U-shape allows for more flexibility and easier installation, particularly in confined spaces.

Material:

Typically made from spring steel, stainless steel, or other high-strength materials to withstand tension and wear.

For applications in high-temperature environments, materials like Inconel or other heat-resistant alloys may be used.

Snap rings for tubes erosion shields

Snap rings are used in conjunction with boiler tubes erosion shields, which is a clip that easily installs boiler tubes erosion shields to the tube.

Snap rings drawing

The snap ring and Boiler Tubes Erosion Shields are overlapped and welded, generally about 190-200 degrees Erosion Shields is a 180-degree semicircle), but also leave a welding position for easy welding and fixing. Generally, each piece of Boiler Tubes Erosion Shields needs to be equipped with 2-4 snap rings with a pitch of 200-500mm.

The anti-wear snap ring is also called clamp, buckle, tube clamp, etc.

The main role of the anti-wear tile snap ring: the role of fixing the anti-wear tile to avoid problems such as the anti-wear tile falling off during installation.

The types of common anti-wear tile rings can be divided into: U-shaped lap type snap ring, butt-type semicircular snap ring.

Compared with the butt-type semicircular snap ring, it is stronger after holding the wear-resistant tile and welding.

C-Shaped Snap Ring

C-shaped snap ring

C-shaped snap ring is the most common snap ring. Mainly based on the size of anti-friction tile, the diameter and thickness are similar to the matching anti-friction tile, and the length varies from 20mm to 70mm. It is mainly connected to the wear-resistant tile by spot welding when installing the wear-resistant tile, so as to fix and prevent the wear-resistant tile from falling off.
