SUS440C stainless steel bearings that are resistant to rust, corrosion, and high temperatures. Each series is available in standard stock.
"Features" 1. It can be used in high-temperature environments compared to SUJ2 bearing steel. 2. A type with a retaining ring is also available in the lineup.
"Rust-free and gentle on the human body," this is a pure titanium bearing that adapts to all special environments.
Features 1. By using two types of pure titanium with excellent corrosion resistance for the inner and outer rings, it can be used in harsher corrosive environments than SUS304 stainless steel bearings. 2. It is safe for the human body, as it does not cause allergic reactions, making it applicable for artificial joints and other medical uses. 3. It is a non-magnetic bearing due to the combination of pure titanium and ceramic balls. Additionally, the combination with ceramic balls provides insulation properties. 4. It has minimal reduction in toughness at low temperatures, allowing for use in low-temperature environments. 5. With a specific gravity of 4.5, it is lower than other materials (SUJ2: specific gravity 7.8), contributing to weight reduction.
By using ceramics for the inner and outer rings and fluororesin for the retainers, it is possible to use them in harsh corrosive environments.
"Features" 1. It is completely non-magnetic because it uses ceramics. 2. It uses a fluororesin holder, allowing it to be used without grease even in environments where grease cannot be used due to high temperatures, etc. 3. The operating temperature is up to 300°C.
This is a bearing that encapsulates fluorine-based heat-resistant grease in SUS440C stainless steel, which has superior heat resistance compared to SUJ2 bearing steel.
"Features" 1. The operating temperature is up to 250°C (excluding seal types). 2. SUS440C stainless steel has a smaller reduction in hardness and dimensional changes under high-temperature environments compared to SUJ2 bearing steel. 3. SUS440C stainless steel excels in oxidation resistance, which is significantly affected in high-temperature environments compared to SUJ2 bearing steel. 4. The inclusion of fluorine-based heat-resistant grease enables lubrication at high temperatures.
It is suitable for high temperatures and vacuum environments where grease cannot be used.
"Features" 1. The operating temperature is up to 300°C (excluding seal types). 2. Smooth rotation can be achieved with low torque (excluding seal types). 3. This is a grease-free bearing. By applying a special coating to the retainer, it can be used in environments where grease cannot be used.
Due to fastening with a stop screw, the set collar for fixing or positioning the bearing is no longer necessary, improving the workability of assembly.
"Features" 1. Prevents creep of the shaft and inner diameter through secure installation with set screws. 2. Eliminates the generation of wear particles due to creep. Suitable for environments that require cleanliness, such as clean rooms. 3. Excellent corrosion resistance.
The outer wheel is a W-shaped bearing. It can be used on rails with an inner V shape or an outer V shape, and can be utilized as a guide wheel for various applications.
"Features" 1. The precision-ground W shape and the integrated bearing structure ensure high accuracy. 2. The internal structure of the bearing is a multi-row angular contact type, allowing it to bear radial and axial loads, and it also has excellent load capacity against moment loads. 3. The materials include SUJ2 bearing steel and SUS440C stainless steel.
By incorporating ceramic balls, it achieves an even longer lifespan than heat-resistant stainless steel bearings.
"Features" 1. The operating temperature is up to 250°C (excluding seal types). 2. It is a hybrid type that incorporates ceramic balls into the inner and outer rings made of SUS440 stainless steel. 3. The ceramic balls reduce internal heat generation, extending the lifespan of the grease. 4. The long lifespan reduces running costs.
It is possible to manufacture optimal bearings by combining materials according to their intended use.
In addition to the inner and outer ring materials, we can also prepare various materials for each component that makes up the bearing and are capable of manufacturing them. ■ Examples of materials (1) Inner and outer rings - SUJ2 (heat stabilization treatment possible) - SUS440C (heat stabilization treatment possible) - SUS304, SUS316L, SUS630 - Titanium, Hastelloy equivalent materials - Ceramics, Resin (2) Balls - SUJ2, SUS440C, SUS304 - Ceramics, Special coatings (3) Retainers - SPCC, S55C, SUS304 - Special coatings, Polyamide resin - Fluororesin, Solid lubricants (4) Shields - SECC, SUS304 (5) Seals - Nitrile rubber, Acrylic rubber - Fluororubber, Fluororesin
