PJB Bearings: Satisfying expanding needs

Bearings, which are integrated into various devices and rotate while supporting loads, are important parts that play active roles as “behind-the-scene players” essential to our lives.
Our company produces bearings of various specifications for diverse industrial fields, including robotics and other leading-edge industries, in small lots of diverse products.
Of these, we focus on extra-miniature/miniature/small bearings, flanged bearings, extra-thin-section bearings and large stainless-steel bearings and meet extensive needs.

The food & beverages field

Bearings used for machinery that comes into contact with food need to be extra safe and corrosion-resistant.
Our company produces stainless-steel bearings filled with grease for food-contact applications on an exclusive assembly line.
These bearings, which are more corrosion-resistant than those made of bearing steel, are used for food processors, food blenders, coffee mills, food/beverage fillers and the like. For sealing, it’s also possible to use fluoro rubber (FKM) seals, which are highly resistant to heat, oils and chemicals.

The medical and nursing field

Extremely high precision is required for bearings used in medical equipment.
Extra-thin-section stainless-steel bearings are used for medical equipment that needs to move efficiently in small spaces, including surgical assistance robots, in-vitro fertilization devices and peristaltic pumps, as well as for leading-edge technologies, such as lifting beds and robot suits for nursing.
For sealing, it’s also possible to use fluoro rubber (FKM) seals, which is highly resistant to heat, oils and chemicals.

The industrial robot field

Another field where high-precision bearings are essential is industrial robots, where outstanding technological advances are being made.
The extra-miniature, miniature, small and extra-thin-section bearings in which our company specializes are used for robot arms and grippers that require precise movements, contributing to the production of smaller, lighter-weight devices.

PJB Bearings: Contributing to “the fourth industrial revolution”

Drivers of “the fourth industrial revolution” are the Internet of Things (IoT, a network where all different things are connected to the Internet and work in a coordinated manner), information and communication technology (ICT), artificial intelligence (AI), and robots used as intelligent mechanical systems.
High-precision bearings are important parts that support the IoT and robots, which are key next-generation technologies. With high-precision miniature bearings, extra-thin-section bearings and stainless-steel bearings, our company provides support in situations that require energy and space savings and next-generation technologies in communications, advanced medical care and robotics, in order to contribute to an IoT society that links people with things and things with other things.
