Plastic Bearings with Inner Stud (Threaded Hole) Specification

This is a bearing with an internally threaded hole. There are various methods to mount bearings, including attaching flanges, fixing with collars at both ends, using retaining rings, pressing into the shaft or housing, etc. For our main products, plastic bearings, the common method is to press fit the outer diameter to secure the bearing. Among these different mounting methods, as shown in the photo, it is also possible to equip the bearing with an internal threaded hole and fix it with a screw. Depending on the bearing size, it is possible to manufacture thread sizes and pitches in the dimensions you specify. If you have any issues with mounting[…..]

Plastic Bearings for Cleaning with Hydrofluoric Acid

This is a plastic bearing that can be used for hydrofluoric acid cleaning of semiconductors and LCDs. We are the only company in Japan that manufactures ball bearings from PCTFE (Polychlorotrifluoroethylene). Plastic Bearings for Cleaning with Hydrofluoric Acid Our bearings have a specification of PCTFE (Poly Chloro Tri Fluoro Ethylene) for the main body and SiC (Silicon Carbide) for the balls. Hydrofluoric acid, used in the cleaning of semiconductors and LCDs, corrodes many metals, plastics, and ceramics. We manufacture PCTFE bearings that are resistant to hydrofluoric acid. PCTFE: Poly Chloro Tri Fluoro Ethylene (Polychlorotrifluoroethylene) is a hard plastic that has proven to be particularly resistant to hydrofluoric acid. Depending on[…..]

Acid-Resistant Plastic Bearings for Use in Highly Acidic Environments

In cleaning systems for semiconductor and LCD industries, there is an aggressive acidic atmosphere that corrodes conventional metal bearings. As a solution in such cases, plastic bearings are employed.
