The Oiless Pillow Block is a sliding bearing unit that incorporates oil-free spherical bearings and possesses numerous excellent features.
The adoption of oil-free bearings offers excellent wear resistance, heat resistance, water resistance, and weather resistance, demonstrating high performance even in areas where lubrication is not possible or under harsh conditions. ■ Easy handling with complete unitization The structure is simple, and since there is an inner ring on the inner diameter surface of the oil-free spherical bearing, installation is easy and similar to rolling types, regardless of the surface roughness of the mounting shaft. ■ Rational self-alignment The fitting surfaces between the oil-free spherical bearing and the bearing housing are precisely machined with a spherical machining machine, eliminating any point contact on the sliding surfaces, making it extremely rational and stress-free, fully utilizing the bearing's performance. ■ Maintenance-free It is highly effective in areas that require constant lubrication, such as food machinery, places where oil-free operation is desirable, locations where user lubrication is not expected, high places, and hazardous areas where lubrication work is difficult. Of course, by combining appropriate lubrication, the bearing life can be extended. ■ Under harsh conditions such as high temperatures and underwater It can be used in high temperatures (up to 250°C), which often pose problems for general bearings, and even underwater. Additionally, it exhibits excellent performance in intermittent operations and oscillating movements, where oil film formation is difficult.
