• Metal bearings

Contributes to cost reduction through simplification of equipment design and improvement of work efficiency. "Features" 1. Corrosion Resistance By using SUS440C stainless steel for the bearings and housing, it excels in corrosion resistance and maintains a clean environment. 2. Self-Aligning Function (SSA Type, SSXCA Type) The self-aligning function allows for easy alignment adjustment during installation, reducing the load on the bearings caused by misalignment or shaft deflection. 3. Fit Since both the bearings and housing are made of SUS440C stainless steel, there is no difference in expansion and contraction under temperature variations, allowing for proper fit. 4. Installation Ideal for areas requiring precise positioning due to its precise finishing. Additionally, the SSXCA type and SSXC type use set screws for fastening to the shaft, making installation easy.

• Metal bearings

The corrosion resistance of stainless steel can also significantly extend the maintenance period. "Features" 1. Corrosion Resistance Since it uses SUS440C stainless steel, it is suitable for corrosive environments, clean rooms, and food machinery. 2. Self-aligning Function It aligns the misalignment of the shaft caused by deflection of conveyor rollers and improper installation, reducing abnormal loads on the bearings. 3. Dust Resistance It is suitable for environments with a lot of dust, powder, and cleaning liquids, as shields and seals can be used. 4. Compatibility It has the same major dimensions as JIS standard series 6200, 6300, 1200, and 1300 (with some exceptions), making replacement easy.

• Metal bearings

"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.

• Metal bearings

"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.

• Metal bearings

"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.

• Metal bearings

"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.

• Metal bearings

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.

• Metal bearings

This is a high corrosion-resistant bearing that achieves high corrosion resistance and high hardness, enabling a long lifespan in all corrosive environments. "Features" 1. It has superior corrosion resistance compared to SUS440C stainless steel bearings. 2. It can be used in larger load and faster rotational ranges than SUS304 stainless steel bearings. 3. It comes standard with fluorine-based chemical-resistant and heat-resistant grease, making it suitable for use in high temperatures and corrosive environments. 4. It is a hybrid type that uses silicon nitride ceramic balls (Si₃N₄).

• Metal bearings

It is suitable for corrosive environments that are difficult to handle with conventional SUS440C stainless steel bearings. "Features" 1. Superior corrosion resistance compared to SUS440C stainless steel bearings. 2. Non-magnetic 3. For light loads and low-speed rotation
